Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning, specifically the variant used by Rust.

0.11.6 - 2018-08-27

Fixed

  • Build with NLL/two-phase borrows
  • Explicitly define [bin] section for discoverer example to fix a cargo warning

Added

  • Add unsafe gst::deinit() function
  • Ord/PartialOrd impls on gst::Seqnum
  • Getter for current pad mode
  • gst::Pad::sticky_events_foreach() for iterating over all sticky events in a thread-safe way

0.11.5 - 2018-07-24

Fixed

  • gst::Bus's sync handler must unref every message if gst::BusSyncReply::Drop is returned, otherwise they are all leaked

0.11.4 - 2018-07-19

Fixed

  • gst::Caps::subtract() does not leak its arguments anymore
  • gst::Caps::get_structure() gracefully returns None if the index is out of bounds instead of a g_return_val_if_fail()
  • gst::Structure::new() has to give away ownership of the info structure but didn't. For 0.11 we internally copy, in 0.12 it will take the info structure by value
  • Typefind tests don't fail anymore if the system has typefind factories without caps

Added

  • An additional assertion that ensures that miniobjects are actually writable before creating a mutable reference

0.11.3 - 2018-06-08

Added

  • gst::Bus::remove_watch() is now available to remove a bus watch again
  • fmt::Debug impls for AudioInfo and VideoInfo were added
  • fmt::Debug impls for mini objects also print the pointer value now to make it easier to track them in debug logs
  • PlayerVisualization has accessors for the name and description fields now, without which there is no sensible way to use them or to set a player visualization

0.11.2 - 2018-05-09

Fixed

  • Work-around various floating reference handling changes between 1.12 and 1.14 to be able to run with both versions without memory leaks or other reference count problems. This affects NetTimeProvider, BufferPool, DeviceMonitor, Stream, StreamCollection, and Player, NetClientClock, NetClock, PtpClock which were already previously fixed.

Changed

  • Change the appsrc need-data and all appsink callbacks to not require the Sync bound anymore and change from Fn to FnMut. They can only be called from a single thread at a time. This change is only done for the corresponding callbacks, not the signals.

0.11.1 - 2018-04-07

Fixed

  • Fix Structure::to_string() to not run into an infinite recursion but call the method on the contained StructureRef instead of on itself

0.11.0 - 2018-03-20

Changed

  • Updated everything to GStreamer 1.14.0
  • Event, Message and Query types were refactored to improve usability. Especially newly constructed queries allow to directly use the type-specific functions to be used without first creating a view
  • VideoFrameRef::copy_to_ref() and ::copy_plane_to_ref() are gone now and the original functions work with refs instead of full frames
  • PadProbeId and NotifyIds are not Copy/Clone anymore and are taken by value
  • GstPlayer has GstObject as parent class now

Added

  • GstPbutils, GstSdp, GstRtsp and GstRtspServer bindings
  • GstPromise, GstAudioStreamAlign and various other 1.14 API
  • GstVideoFilter and GstBufferPool bindings
  • Element::call_async()
  • Debug impl For Toc and TocEntry
  • Various new examples (RTP FEC, RTSP server, tag usage, ...)

Fixed

  • Memory leak in gst_video::convert_sample_async()

0.10.2 - 2018-02-18

Fixed

  • Fix building of messages with custom fields for types that don't have a GstStructure

Added

  • VideoFrameRef::copy_to_ref() and ::copy_plane_to_ref(), which work with VideoFrameRefs instead of full VideoFrames
  • Getters for the BaseSrc/Sink/Transform configured segment
  • Document the gstreamer-player-1.0 dependency in the README.md

0.10.1 - 2018-01-03

Fixed

  • Don't require &mut self for TagSetterExtManual::add()

Added

  • A TagSetter example application
  • Bindings for gst_video::convert_sample() and ::convert_sample_async()
  • Bindings for gst_video::VideoRectangle
  • Debug impl for Sample and ::with_buffer_list() constructor
  • A borrowing version of VideoFrame: VideoFrameRef
  • Bindings for GstVideoFilter

Changed

  • Deprecated Sample::get_info() in favour of ::get_structure()
  • Player has gst::Object as another parent class now

0.10.0 - 2017-12-22

Fixed

  • Various clippy warnings
  • Memory leak of the tag list in Toc::merge_tags()
  • Property getters use Values of the correct type
  • Event::get_structure(), Message::get_structure() and Query::get_structure() can return None for the structure
  • Various other nullability fixes all over the API, changing functions to accept Option<> or returning Option<>, or only plain types
  • Functions taking paths/filenames now actually take Paths instead of &strs
  • Element::remove_pad() is not giving away a new reference to the pad anymore, which caused a memory leak of all pads ever removed
  • Precision handling in ClockTime's Display impl
  • Video/AudioInfo are only Send, not Sync

Added

  • Various enums now also derive useful traits like Copy, Clone and Hash in addition to PartialEq, Eq and Debug
  • TagList::merge() and insert() for combining tag lists
  • EventType gained many useful functions to work with event types and a PartialOrd impl to check expected event order of event types where it matters
  • MessageRef/EventRef/QueryRef implement ToOwned
  • Bindings for Registry and PluginFeature
  • Event::set_running_time_offset() for adjusting the offset while events pass through the pipeline
  • Event/Message GroupIds and Seqnums now have a newtype wrapper around u32 instead of the plain value, making usage of them slightly more typesafe. Also add an "invalid" value for both, as exists in latest GStreamer now.
  • FormattedValue, GenericFormattedValue and related types were implemented now, which allows more convenient and type-safe usage of formatted values (time, bytes, etc)
  • Bindings for force-keyunit and still-frame events were added
  • MappedBuffer/BufferMap now implement various other useful traits, including AsRef<[u8]>, AsMut, Deref, DerefMut, Debug, PartialEq and Eq
  • Add VideoMultiviewFramePacking enum, and use it in Player
  • Bindings for the GStreamer Net library, including PTP/NTP/network client clocks and the GStreamer NetClock provider for network synchronization of pipelines
  • IteratorError implements std::error:Error
  • Plugin::add_dependency() and ::add_dependency_simple() was added
  • Rank and TypeFindProbability implement PartialOrd/Ord now
  • Bindings for TypeFind, TypeFindFactory and the typefind helpers
  • StreamCollection::iter() for iterating over all contained streams
  • ErrorMessage type that can be used e.g. in a Result for passing an error message from somewhere to upper layers to then be posted on an element the same way gst_element_error!() would've done

Changed

  • Sample::new(), TagList::add(), Structure::set() and similar functions take the values (ToSendValue impls) by reference instead of value. They were not consumed by the function before.
  • The Debug impls of various types, including Event/Buffer/Message/Query/Structure were improved to print all the fields, similar to what GST_PTR_FORMAT would do in C
  • Switched to lazy_static 1.0
  • Gap event and Duration tag are using ClockTimes now, as well as various Player signals
  • Segment is now based on a generic type FormattedSegment that can take any format (time, bytes, etc) or a GenericFormattedValue for more type-safety and convenience. Also functions for "casting" between a generic segment and a segment with a specific format exist on this now
  • AppSrc and AppSink now have a builder for the callbacks, making it unnecessary to always provide all callbacks even if only one is actually needed
  • Various functions that returned bool for errors, are now returning a Result
  • Player configuration is now a custom type with more convenient API
  • Player VideoInfo uses a Fraction instead of (u32,u32) for the framerate and pixel-aspect-ratio
  • VideoFrame API has more consistent API between writable and read-only variants
  • Buffer::copy_into() was added, and ::copy_region() now takes a BufferCopyFlags parameter instead of always using the default flags
  • ChildProxy::set_child_property() takes a &ToValue now to follow the API of Object::set_property() and improve usability
  • Proxy/GhostPad default pad functions use the correct specific pad type now instead of a generic Pad
  • Bus::add_signal_watch_full() takes a Priority for the priority instead of u32
  • Clock::(un)adjust_with_calibration() takes no clock parameter anymore

Removed

  • FormatValue was removed in favour of GenericFormattedValue and the connected traits and specific format impls

0.9.1 - 2017-11-26

Fixed

  • Export FlowError/FlowSuccess, ClockError/ClockSuccess, PadLinkError/PadLinkSuccess too

0.9.0 - 2017-11-26

Added

  • Bindings for (outputting to) the GStreamer logging system
  • Bindings for the GStreamer base library
  • Bindings for all the Pad functions to override pad behaviour, and pad task functions
  • Bindings for StaticCaps and StaticPadTemplate
  • Bindings for deep-notify signal on Object
  • Support for directly creating Error/Warning/Info Messages and posting them from an element with context information (file, line, module, etc.) similar to the C GST_ELEMENT_ERROR macro
  • Support for setting custom fields in Messages/Events during construction
  • Support for creating Buffers out of anything that is AsRef<[u8]> or AsMut<[u8]>
  • Support for using the Read trait on Adapter
  • Functions for getting all sink/src/all pads of an Element, and all children of a Bin
  • Builder for Caps and Structures in addition to the existing functions
  • AppSrc/AppSink implement BaseSrc/BaseSink and URIHandler
  • Rust ports of the basic tutorials 1 to 8 from https://gstreamer.freedesktop.org/documentation/tutorials/
  • "Getting started" and "Installation" sections to the README.md
  • "dox" feature for generating documentation for all available configurations

Fixed

  • StackTraceFlags are only available since 1.12
  • Worked around macOS requiring a NSRunLoop running on the main thread in all examples and tutorials, to be able to show a window or anything else

Changed

  • ClockTime is now a wrapper around Option<u64> to handle the CLOCK_TIME_NONE case better. This wrapper implements all the arithmetic and other traits as needed and ensures that no accidential calculations with CLOCK_TIME_NONE can happen

  • "Values with format", like in Duration/Position/Convert queries or Seek events now return a FormatValue type. This contains the actual Format together with the value and does any required conversions. This also makes it harder to accidentially mix e.g. values in bytes and time

  • PadProbeId does not implement Clone/Copy anymore

  • Property notify watches return a custom type instead of ulong

  • Error/Warning/Info Messages can only be created with specific kinds of glib::Error now. Using arbitrary ones does not work

  • Iterator bindings were completely rewritten and provide the item type as a generic type parameter now, greatly simplifying its usage

  • All glib::Values are now glib::SendValue instead, e.g. in Caps and Structures, as their content must be possible to send to different threads safely

  • Message::get_src() can return None

  • Allow None as Caps in AppSrc/AppSink

  • Allow everything implementing Into<Option<&str>> to be used as a pad name

  • Moved copy() from GstRc directly to MiniObject

  • Success/Error enums (like FlowReturn, PadLinkReturn, StateChangeReturn) now implement an into_result() function that splits them into a Result with the good and bad cases. Also mark them as #[must_use] to make it harder to accidentially ignore errors.

  • Error enums implement the Error trait

  • Many examples use the failure crate for error handling now, cleaning up the error handling code quite a bit

  • Lots of other code cleanup, compiler/clippy warning cleanup, etc.

0.8.2 - 2017-11-11

Fixed

  • Implement StaticType of BufferRef instead of Buffer. Buffer aka GstRc already implements StaticType if BufferRef does, and without this it was not possible to use Buffers in GValues.
  • Free memory of the appsink/appsrc callbacks with the correct type. It was crashing because of using the wrong type before.
  • Fix documentation URLs in Cargo.toml.

Added

  • Installation instructions and links to documentation for getting started to README.md.

0.8.1 - 2017-09-15

Added

  • Implement Send+Sync for Query, Message and Event, and their corresponding Ref types.

Fixed

  • Constructor for gst_player::Player now works properly with GStreamer 1.12 when passing a video renderer or signal dispatcher. There was a reference counting bug.
  • Instead of returning &'static references from functions, return references with a generic, unbound lifetime instead. See https://github.com/rust-lang/rust/pull/42417#issue-233404573
  • Various "unused external crate" warnings and clippy warnings everywhere.

Changed

  • Remove Cargo.lock from GIT, it's not very useful for library crates.
  • Run everything through latest rustfmt-nightly.
  • Use while-let (instead of loop and if-let) and CLOCK_TIME_NONE (instead of u64::MAX) in the examples.

[0.8.0] - 2017-08-31

  • Initial release of the autogenerated GStreamer bindings. Older versions (< 0.8.0) of the bindings can be found here. The API of the two is incompatible.
