Theoretically parsers should be able to + fix this up, but it would probably require fairly invasive changes + in the parsers, so two new elements h264timestamper and + h265timestamper bridge the gap in the meantime and can reconstruct + missing PTS/DTS. + +Easy sender timestamp reconstruction for RTP and RTSP + +- it was always possible to reconstruct and retrieve the original RTP + sender timestamps in GStreamer, but required a fair bit of + understanding of the internal mechanisms and the right property + configuration and clock setup. + +- rtspsrc and rtpjitterbuffer gained a new + “add-reference-timestamp-meta” property that if set puts the + original absolute reconstructed sender timestamps on the output + buffers via a meta. This is particularly useful if the sender is + synced to an NTP clock or PTP clock. The original sender timestamps + are either based on the RTCP NTP times, NTP RTP header extensions + (RFC6051) or RFC7273-style clock signalling. + +Qt6 support + +- new qml6glsink element for Qt6 similar to the existing Qt5 element. + Matching source and overlay elements will hopefully follow in the + near future. + +OpenGL + Video library enhancements + +- Support for new video formats (NV12_4L4, NV12_16L32S, NV12_8L128, + NV12_10BE_8L128) and dmabuf import in more formats (Y410, Y212_LE, + Y212_BE, Y210, NV21, NV61) + +- Improved support for tiled formats with arbitrary tile dimensions, + as needed by certain hardware decoders/encoders + +- glvideomixer: New “crop-left,”crop-right, “crop-top” and + “crop-bottom” pad properties for cropping inputs + +- OpenGL support for gst_video_sample_convert(): + + - Used for video snapshotting and thumbnailing, to convert buffers + retrieved from appsinks or sink “last-sample” properties in + JPG/PNG thumbnails. + - This function can now take samples and buffers backed by GL + textures as input and will automatically plug a gldownload + element in that case. + +High bit-depth support (10, 12, 16 bits per component value) improvements + +- compositor can now handle any supported input format and also mix + high-bitdepth (10-16 bit) formats (naively) + +- videoflip has gained support for higher bit depth formats. + +- vp9enc, vp9dec now support 12-bit formats and also 10-bit 4:4:4 + +WebRTC + +- Allow insertion of bandwidth estimation elements e.g. for Google + Congestion Control (GCC) support + +- Initial support for sending or receiving simulcast streams + +- Support for asynchronous host resolution for STUN/TURN servers + +- GstWebRTCICE was split into base classes and implementation to make + it possible to plug custom ICE implementations + +- webrtcsink: batteries-included WebRTC sender (Rust) + +- whipsink: WebRTC HTTP ingest (WHIP) to a MediaServer (Rust) + +- whepsrc: WebRTC HTTP egress (WHEP) from a MediaServer (Rust) + +- Many other improvements and bug fixes + +New HLS, DASH and MSS adaptive streaming clients + +A new set of “adaptive demuxers” to support HLS, DASH and MSS adaptive +streaming protocols has been added. They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives. This approach is only compatible with Gtk3, + and like gtksink this element only supports Gtk3. + +- new h264timestamper and h265timestamper elements to reconstruct + missing pts/dts from inputs that might not provide them such as + e.g. RTP/RTSP/WebRTC inputs (see above) + +- mfaacdec, mfmp3dec: Windows MediaFoundation AAC and MP3 decoders + +- new msdkav1enc AV1 video encoder element + +- new nvcudah264enc, nvcudah265enc, nvd3d11h264enc, and nvd3d11h265enc + NVIDIA GPU encoder elements to support zero-copy encoding, via CUDA + and Direct3D11 APIs, respectively + +- new nvautogpuh264enc and nvautogpuh265enc NVIDIA GPU encoder + elements: The auto GPU elements will automatically select a target + GPU instance in case multiple NVIDIA desktop GPUs are present, also + taking into account the input memory.

Those + new elements are useful if target GPU and/or API mode (either CUDA + or Direct3D11 in case of Windows) is undeterminable from the encoder + point of view at the time when pipeline is configured, and therefore + lazy target GPU and/or API selection are required in order to avoid + unnecessary memory copy operations. + +- new nvav1dec AV1 NVIDIA desktop GPU decoder element + +- new qml6glsink element to render video with Qt6 + +- qsv: New Intel OneVPL/MediaSDK (a.k.a Intel Quick Sync) based + decoder and encoder elements, with gst-d3d11 (on Windows) and gst-va + (on Linux) integration + + - Support multi-GPU environment, for example, concurrent video + encoding using Intel iGPU and dGPU in a single pipeline + - H.264 / H.265 / VP9 and JPEG decoders + - H.264 / H.265 / VP9 / AV1 / JPEG encoders with dynamic encoding + bitrate update + - New plugin does not require external SDK for building on Windows + +- vulkanoverlaycompositor: new vulkan overlay compositor element to + overlay upstream GstVideoOverlayCompositonMeta onto the video + stream. + +- vulkanshaderspv: performs operations with SPIRV shaders in Vulkan + +- win32ipcvideosink, win32ipcvideosrc: new shared memory videosrc/sink + elements for Windows + +- wicjpegdec, wicpngdec: Windows Imaging Component (WIC) based JPEG + and PNG decoder elements. + +- Many exciting new Rust elements, see Rust section below New element features and additions -- this section will be filled in in due course +- audioconvert: Dithering now uses a slightly slower, less biased PRNG + which results in better quality output.

General improvements -- this section will be filled in in due course +- Rust support was added for all support configurations, controlled by + the rust variant; see above for more details +- All pkgconfig files are now reliably relocatable without requiring + pkg-config --define-prefix. This also fixes statically linking with + GStreamer plugins using the corresponding pkgconfig files. +- New documentation on how to build a custom GStreamer repository + using Cerbero, please see the README +- HTTPS certificate checking is enabled for downloads on all platforms + now +- Fetching now automatically retries on error for robustness against + transient errors +- Support for building the new Qt6 plugin was added +- pkgconfig files for various recipes were fixed +- Several recipes were updated to newer versions +- New plugins: adaptivedemux2 aes codectimestamper dav1d +- New libraries: cuda webrtcnice macOS / iOS -- this section will be filled in in due course +- Added support for running Cerbero on ARM64 macOS +- GStreamer.framework and all libraries in it are now relocatable, + which means they use LC_RPATH entries to find dependencies instead + of using an absolute path. If you link to GStreamer using the + pkgconfig files, no action is necessary. However, if you use the + framework directly or link to the libraries inside the framework by + hand, then you need to pass -Wl,-rpath, to the + linker. +- Apple bitcode support was dropped, since Apple has deprecated it +- macOS installer now correctly advertises support for both x86_64 and + arm64 +- macOS framework now ships the gst-rtsp-server-1.0 library +- Various fixes were made to make static linking to gstreamer + libraries and plugins work correctly on macOS +- When statically linking to the applemedia plugin using Xcode 13, you + will need to pass -fno-objc-msgsend-selector-stubs which works + around a backwards-incompatible change in Xcode 14.

Please see the + README for more details. Some advantages include: + - Faster build times, since parallel make works + - Faster bootstrap, since some tools are provided by MSYS2 + - Other speed-ups due to using MSYS2 tools instead of MSYS +- Faster download by using powershell instead of hand-rolled Python + code +- Many recipes were ported from Autotools to Meson, speeding up the + build +- Universal Windows Platform is no longer supported, and binaries are + no longer shipped for it +- New documentation on how to force a specific Visual Studio + installation in Cerbero, please see the README +- New plugins: qsv wavpack directshow amfcodec wic win32ipc +- New libraries: d3d11 Windows MSI installer -- this section will be filled in in due course +- Universal Windows Platform prebuilt binaries are no longer available Linux -- this section will be filled in in due course +- Various fixes for RHEL/CentOS 7 support +- Added support for running on Linux ARM64 Android -- this section will be filled in in due course +- Android support now requires Android API version 21 (Lollipop) +- Support for Android Gradle plugin 7.2 Platform-specific changes and improvements Android -- this section will be filled in in due course +- Android SDK 21 is required now as minimum SDK version -macOS and iOS +- androidmedia: Add H.265 / HEVC video encoder mapping -- this section will be filled in in due course +- Implement JNI_OnLoad() to register static plugins etc. automatically + in case GStreamer is loaded from Java using System.loadLibrary(), + which is also useful for the gst-full deployment scenario. + +Apple macOS and iOS + +- The GLib version shipped with the GStreamer binaries does not + initialize an NSApp and does not run a NSRunLoop on the main thread + anymore. This was a custom GLib patch and caused it to behave + different from the GLib shipped by Homebrew or anybody else. + + The change was originally introduced because various macOS APIs + require a NSRunLoop to run on the main thread to function correctly + but as this change will never get merged into GLib and it was + reverted for 1.22. Applications that relied on this behaviour should + move to the new gst_macos_main() function, which also does not + require the usage of a GMainLoop. + + See e.g. gst-play.c for an example for the usage of + gst_macos_main(). + +- GStreamer.framework and all libraries in it are now relocatable, + which means they use LC_RPATH entries to find dependencies instead + of using an absolute path. If you link to GStreamer using the + pkgconfig files, no action is necessary. However, if you use the + framework directly or link to the libraries inside the framework by + hand, then you need to pass -Wl,-rpath, to the + linker. + +- avfvideosrc: Allow specifying crop coordinates during screen capture + +- vtenc, vtdec: H.265 / HEVC video encoding + decoding support + +- osxaudiosrc: Support a device as both input and output + + - osxaudiodeviceprovider now probes devices more than once to + determine if the device can function as both an input AND and + output device. Previously, if the device provider detected that + a device had any output capabilities, it was treated solely as + an Audio/Sink. This caused issues for devices that have both + input and output capabilities (for example, USB interfaces for + professional audio have both input and output channels). Such + devicesare now listed as both an Audio/Sink as well as an + Audio/Source. + +- osxaudio: support hidden devices on macOS + + - These are devices that will not be shown in the macOS UIs and + that cannot be retrieved without having the specific UID of the + hidden device. There are cases when you might want to have a + hidden device, for example when having a virtual speaker that + forwards the data to a virtual hidden input device from which + you can then grab the audio. The blackhole project supports + these hidden devices and this change provides a way that if the + device id is a hidden device it will use it instead of checkinf + the hardware list of devices to understand if the device is + valid. Windows -- this section will be filled in in due course +- win32ipcvideosink, win32ipcvideosrc: new shared memory videosrc/sink + elements + +- wasapi2: Add support for process loopback capture for a specified + PID (requires Windows 11/Windows Server 2022) - The Windows universal UWP build is currently non-functional and will need updating after the recent GLib upgrade. It is unclear if anyone is using these binaries, so if you are please make yourself known. +- wicjpegdec, wicpngdec: Windows Imaging Component (WIC) based JPEG + and PNG decoder elements. + +- mfaacdec, mfmp3dec: Windows MediaFoundation AAC and MP3 decoders + +- The uninstalled development environment supports PowerShell 7 now + Linux -- this section will be filled in in due course +- Improved design for DMA buffer sharing and modifier handling for + hardware-accelerated video decoders/encoders/filters and + capture/rendering on Linux and Linux-like system. + +- kmssink + + - new “fd” property which allows an application to provide their + own opened DRM device fd handle to kmssink. That way an + application can lease multiple fd’s from a DRM master to display + on different CRTC outputs at the same time with multiple kmssink + instances, for example. + - new “skip-vsync” property to achieve full framerate with legacy + emulation in drivers. + - HDR10 infoframe support + +- va plugin and gstreamer-vaapi improvements (see above) + +- waylandsink: Add “rotate-method” property and “render-rectangle” + property + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives. This approach is only compatible with Gtk3, + and like gtksink this element only supports Gtk3.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.

On Windows CUDA or Direct3D11 + mode will be determined by the elements automatically as well. Those + new elements are useful if target GPU and/or API mode (either CUDA + or Direct3D11 in case of Windows) is undeterminable from the encoder + point of view at the time when pipeline is configured, and therefore + lazy target GPU and/or API selection are required in order to avoid + unnecessary memory copy operations. + +- new nvav1dec AV1 NVIDIA desktop GPU decoder element + +- new qml6glsink element to render video with Qt6 + +- qsv: New Intel OneVPL/MediaSDK (a.k.a Intel Quick Sync) based + decoder and encoder elements, with gst-d3d11 (on Windows) and gst-va + (on Linux) integration + + - Support multi-GPU environment, for example, concurrent video + encoding using Intel iGPU and dGPU in a single pipeline + - H.264 / H.265 / VP9 and JPEG decoders + - H.264 / H.265 / VP9 / AV1 / JPEG encoders with dynamic encoding + bitrate update + - New plugin does not require external SDK for building on Windows + +- vulkanoverlaycompositor: new vulkan overlay compositor element to + overlay upstream GstVideoOverlayCompositonMeta onto the video + stream. + +- vulkanshaderspv: performs operations with SPIRV shaders in Vulkan + +- win32ipcvideosink, win32ipcvideosrc: new shared memory videosrc/sink + elements for Windows + +- wicjpegdec, wicpngdec: Windows Imaging Component (WIC) based JPEG + and PNG decoder elements. + +- Many exciting new Rust elements, see Rust section below New element features and additions -- this section will be filled in in due course +- audioconvert: Dithering now uses a slightly slower, less biased PRNG + which results in better quality output.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.

On Windows CUDA or Direct3D11 + mode will be determined by the elements automatically as well. Those + new elements are useful if target GPU and/or API mode (either CUDA + or Direct3D11 in case of Windows) is undeterminable from the encoder + point of view at the time when pipeline is configured, and therefore + lazy target GPU and/or API selection are required in order to avoid + unnecessary memory copy operations. + +- new nvav1dec AV1 NVIDIA desktop GPU decoder element + +- new qml6glsink element to render video with Qt6 + +- qsv: New Intel OneVPL/MediaSDK (a.k.a Intel Quick Sync) based + decoder and encoder elements, with gst-d3d11 (on Windows) and gst-va + (on Linux) integration + + - Support multi-GPU environment, for example, concurrent video + encoding using Intel iGPU and dGPU in a single pipeline + - H.264 / H.265 / VP9 and JPEG decoders + - H.264 / H.265 / VP9 / AV1 / JPEG encoders with dynamic encoding + bitrate update + - New plugin does not require external SDK for building on Windows + +- vulkanoverlaycompositor: new vulkan overlay compositor element to + overlay upstream GstVideoOverlayCompositonMeta onto the video + stream. + +- vulkanshaderspv: performs operations with SPIRV shaders in Vulkan + +- win32ipcvideosink, win32ipcvideosrc: new shared memory videosrc/sink + elements for Windows + +- wicjpegdec, wicpngdec: Windows Imaging Component (WIC) based JPEG + and PNG decoder elements. + +- Many exciting new Rust elements, see Rust section below New element features and additions -- this section will be filled in in due course +- audioconvert: Dithering now uses a slightly slower, less biased PRNG + which results in better quality output.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives. This approach is only compatible with Gtk3, + and like gtksink this element only supports Gtk3. + +- new h264timestamper and h265timestamper elements to reconstruct + missing pts/dts from inputs that might not provide them such as + e.g. RTP/RTSP/WebRTC inputs (see above) + +- mfaacdec, mfmp3dec: Windows MediaFoundation AAC and MP3 decoders + +- new msdkav1enc AV1 video encoder element + +- new nvcudah264enc, nvcudah265enc, nvd3d11h264enc, and nvd3d11h265enc + NVIDIA GPU encoder elements to support zero-copy encoding, via CUDA + and Direct3D11 APIs, respectively + +- new nvautogpuh264enc and nvautogpuh265enc NVIDIA GPU encoder + elements: The auto GPU elements will automatically select a target + GPU instance in case multiple NVIDIA desktop GPUs are present, also + taking into account the input memory.

Theoretically parsers should be able to + fix this up, but it would probably require fairly invasive changes + in the parsers, so two new elements h264timestamper and + h265timestamper bridge the gap in the meantime and can reconstruct + missing PTS/DTS. + +Easy sender timestamp reconstruction for RTP and RTSP + +- it was always possible to reconstruct and retrieve the original RTP + sender timestamps in GStreamer, but required a fair bit of + understanding of the internal mechanisms and the right property + configuration and clock setup. + +- rtspsrc and rtpjitterbuffer gained a new + “add-reference-timestamp-meta” property that if set puts the + original absolute reconstructed sender timestamps on the output + buffers via a meta.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives. This approach is only compatible with Gtk3, + and like gtksink this element only supports Gtk3. + +- new h264timestamper and h265timestamper elements to reconstruct + missing pts/dts from inputs that might not provide them such as + e.g. RTP/RTSP/WebRTC inputs (see above) + +- mfaacdec, mfmp3dec: Windows MediaFoundation AAC and MP3 decoders + +- new msdkav1enc AV1 video encoder element + +- new nvcudah264enc, nvcudah265enc, nvd3d11h264enc, and nvd3d11h265enc + NVIDIA GPU encoder elements to support zero-copy encoding, via CUDA + and Direct3D11 APIs, respectively + +- new nvautogpuh264enc and nvautogpuh265enc NVIDIA GPU encoder + elements: The auto GPU elements will automatically select a target + GPU instance in case multiple NVIDIA desktop GPUs are present, also + taking into account the input memory.

Theoretically parsers should be able to + fix this up, but it would probably require fairly invasive changes + in the parsers, so two new elements h264timestamper and + h265timestamper bridge the gap in the meantime and can reconstruct + missing PTS/DTS. + +Easy sender timestamp reconstruction for RTP and RTSP + +- it was always possible to reconstruct and retrieve the original RTP + sender timestamps in GStreamer, but required a fair bit of + understanding of the internal mechanisms and the right property + configuration and clock setup. + +- rtspsrc and rtpjitterbuffer gained a new + “add-reference-timestamp-meta” property that if set puts the + original absolute reconstructed sender timestamps on the output + buffers via a meta.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.

Theoretically parsers should be able to + fix this up, but it would probably require fairly invasive changes + in the parsers, so two new elements h264timestamper and + h265timestamper bridge the gap in the meantime and can reconstruct + missing PTS/DTS. + +Easy sender timestamp reconstruction for RTP and RTSP + +- it was always possible to reconstruct and retrieve the original RTP + sender timestamps in GStreamer, but required a fair bit of + understanding of the internal mechanisms and the right property + configuration and clock setup. + +- rtspsrc and rtpjitterbuffer gained a new + “add-reference-timestamp-meta” property that if set puts the + original absolute reconstructed sender timestamps on the output + buffers via a meta.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives. This approach is only compatible with Gtk3, + and like gtksink this element only supports Gtk3. + +- new h264timestamper and h265timestamper elements to reconstruct + missing pts/dts from inputs that might not provide them such as + e.g. RTP/RTSP/WebRTC inputs (see above) + +- mfaacdec, mfmp3dec: Windows MediaFoundation AAC and MP3 decoders + +- new msdkav1enc AV1 video encoder element + +- new nvcudah264enc, nvcudah265enc, nvd3d11h264enc, and nvd3d11h265enc + NVIDIA GPU encoder elements to support zero-copy encoding, via CUDA + and Direct3D11 APIs, respectively + +- new nvautogpuh264enc and nvautogpuh265enc NVIDIA GPU encoder + elements: The auto GPU elements will automatically select a target + GPU instance in case multiple NVIDIA desktop GPUs are present, also + taking into account the input memory.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.

Theoretically parsers should be able to + fix this up, but it would probably require fairly invasive changes + in the parsers, so two new elements h264timestamper and + h265timestamper bridge the gap in the meantime and can reconstruct + missing PTS/DTS. + +Easy sender timestamp reconstruction for RTP and RTSP + +- it was always possible to reconstruct and retrieve the original RTP + sender timestamps in GStreamer, but required a fair bit of + understanding of the internal mechanisms and the right property + configuration and clock setup. + +- rtspsrc and rtpjitterbuffer gained a new + “add-reference-timestamp-meta” property that if set puts the + original absolute reconstructed sender timestamps on the output + buffers via a meta.

They provide improved performance, +new features and better stream compatibility compared to the previous +elements. These new elements require a “streams-aware” pipeline such as +playbin3, uridecodebin3 or urisourcebin. + +The previous elements’ design prevented implementing several use-cases +and fixing long-standing issues. The new elements were re-designed from +scratch to tackle those: + +- Scheduling Only 3 threads are present, regardless of the number of + streams selected. One in charge of downloading fragments and + manifests, one in charge of outputting parsed data downstream, and + one in charge of scheduling. This improves performance, resource + usage and latency. + +- Better download control The elements now directly control the + scheduling and download of manifests and fragments using libsoup + directly instead of depending on external elements for downloading. + +- Stream selection, only the selected streams are downloaded. This + improves bandwith usage. Switching stream is done in such a way to + ensure there are no gaps, meaning the new stream will be switched to + only once enough data for it has been downloaded. + +- Internal parsing, the downloaded streams are parsed internally. This + allows the element to fully respect the various specifications and + offer accurate buffering, seeking and playback. This is especially + important for HLS streams which require parsing for proper + positioning of streams. + +- Buffering and adaptive rate switching, the new elements handle + buffering internally which allows them to have a more accurate + visibility of which bandwith variant to switch to. + +Playbin3, Decodebin3, UriDecodebin3, Parsebin improvements + +The “new” playback elements introduced in 1.18 (playbin3 and its various +components) have been refactored to allow more use-cases and improve +performance. They are no longer considered experimental, so applications +using the legacy playback elements (playbin and (uri)decodebin) can +migrate to the new components to benefit from these improvements. + +- Gapless The “gapless” feature allows files and streams to be + fetched, buffered and decoded in order to provide a “gapless” + output. This feature has been refactored extensively in the new + components: + - A single (uri)decodebin3 (and therefore a single set of + decoders) is used. This improves memory and cpu usage, since on + identical codecs a single decoder will be used. + - The “next” stream to play will be pre-rolled “just-in-time” + thanks to the buffering improvements in urisourcebin (see below) + - This feature is now handled at the uridecodebin3 level. + Applications that wish to have a “gapless” stream and process it + (instead of just outputting it, for example for transcoding, + retransmission, …) can now use uridecodebin3 directly. Note that + a streamsynchronizer element is required in that case. +- Buffering improvements The urisourcebin element is in charge of + fetching and (optionally) buffering/downloading the stream. It has + been extended and improved: + - When the parse-streams property is used (by default in + uridecodebin3 and playbin3), compatible streams will be demuxed + and parsed (via parsebin) and buffering will be done on the + elementary streams. This provides a more accurate handling of + buffering. Previously buffering was done on a best-effort basis + and was mostly wrong (i.e. downloading more than needed). + - Applications can use urisourcebin with this property as a + convenient way of getting elementary streams from a given URI. + - Elements can handle buffering themselves (such as the new + adaptive demuxers) by answering the GST_QUERY_BUFFERING query. + In that case urisourcebin will not handle it. +- Stream Selection Efficient stream selection was previously only + possible within decodebin3. The downside is that this meant that + upstream elements had to provide all the streams from which to chose + from, which is inefficient. With the addition of the + GST_QUERY_SELECTABLE query, this can now be handled by elements + upstream (i.e. sources) + - Elements that can handle stream selection internally (such as + the new adaptive demuxer elements) answer that query, and handle + the stream selection events themselves. + - In this case, decodebin3 will always process all streams that + are provided to it. +- Instant URI switching This new feature allows switching URIs + “instantly” in playbin3 (and uridecodebin3) without having to change + states. This mimics switching channels on a television. + - If compatible, decoders will be re-used, providing lower + latency/cpu/memory than by switching states. + - This is enabled by setting the instant-uri property to true, + setting the URI to switch to immediately, and then disabling the + instant-uri property again afterwards. +- playbin3, decodebin3, uridecodebin3, parsebin, and urisrc are no + longer experimental + - They were originally marked as ‘technology preview’ but have + since seen extensive usage in production settings, so are + considered ready for general use now. + +Fraunhofer AAC audio encoder HE-AAC and AAC-LD profile support + +- fdkaacenc: + - Support for encoding to HE-AACv1 and HE-AACv2 profile + - Support for encoding to AAC Low Delay (LD) profile + - Advanced bitrate control options via new “rate-control”, + “vbr-preset”, “peak-bitrate”, and “afterburner” properties + +RTP rapid synchronization support in the RTP stack (RFC6051) + +RTP provides several mechanisms how streams can be synchronized relative +to each other, and how absolute sender times for RTP packets can be +obtained. One of these mechanisms is via RTCP, which has the +disadvantage that the synchronization information is only distributed +out-of-band and usually some time after the start. + +GStreamer’s RTP stack, specifically the rtpbin, rtpsession and +rtpjitterbuffer elements, now also have support for retrieving and +sending the same synchronization information in-band via RTP header +extensions according to RFC6051 (Rapid Synchronisation of RTP Flows). +Only 64-bit timestamps are supported currently. + +This provides per packet synchronization information from the very +beginning of a stream and allows accurate inter-stream, and (depending +on setup) inter-device, synchronization at the receiver side. + +ONVIF XML Timed Metadata support + +The ONVIF standard implemented by various security cameras also +specifies a format for timed metadata that is transmitted together with +the audio/video streams, usually over RTSP. + +Support for this timed metadata is implemented in the MP4 demuxer now as +well as the new fragmented MP4 muxer and the new non-fragmented MP4 +muxer from the GStreamer Rust plugins. Additionally, the new onvif +plugin ‒ which is part of the GStreamer Rust plugins ‒ provides general +elements for handling the metadata and e.g. overlaying certain parts of +it over a video stream. + +As part of this support for absolute UTC times was also implemented +according to the requirements of the ONVIF standards in the +corresponding elements. + +MP3 gapless playback support + +While MP3 can probably considered a legacy format at this point, a new +feature was added with this release. + +When playing back plain MP3 files, i.e. outside a container format, +switches between files can now be completely gapless if the required +metadata is provided inside the file. There is no standardized metadata +for this, but the LAME MP3 encoder writes metadata that can be parsed by +the mpegaudioparse element now and forwarded to decoders for ensuring +removal of padding samples at the front and end of MP3 files. + +“force-live” property for audio + video aggregators + +This is a quality of life fix for playout and streaming applications +where it is common to have audio and video mixer elements that should +operate in live mode from the start and produce output continuously. + +Often one would start a pipeline without any inputs hooked up to these +mixers in the beginning, and up until now there was no way to easily +force these elements into live mode from the start. One would have to +add an initial live video or audio test source as dummy input to achieve +this. + +The new “force-live” property makes these audio and video aggregators +start in live mode without the need for any dummy inputs, which is +useful for scenarios where inputs are only added after starting the +pipeline. + +This new property should usually be used in connection with the +“min-upstream-latency” property, i.e. you should always set a non-0 +minimum upstream latency then. + +This is now supported in all GstAudioAggregator and GstVideoAggregator +subclasses such as audiomixer, audiointerleave, compositor, +glvideomixer, d3d11compositor, etc. + +New elements and plugins + +- new cudaconvertscale element that can convert and scale in one pass + +- new gtkwaylandsink element based on gtksink, but similar to + waylandsink and uses Wayland APIs directly instead of rendering with + Gtk/Cairo primitives.
