|
||||||
|
|
||||||
|
[GStreamer](https://gstreamer.freedesktop.org/) (App library) bindings for Rust.
|
||||||
|
Documentation can be found [here](https://gstreamer.pages.freedesktop.org/gstreamer-rs/stable/latest/docs/gstreamer_app/).
|
||||||
|
|
||||||
|
These bindings are providing a safe API that can be used to interface with
|
||||||
|
GStreamer, e.g. for writing GStreamer-based applications and GStreamer plugins.
|
||||||
|
|
||||||
|
The bindings are mostly autogenerated with [gir](https://github.com/gtk-rs/gir/)
|
||||||
|
based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
|
||||||
|
API metadata provided by the GStreamer project.

|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
To build the GStreamer bindings or anything depending on them, you need to
|
||||||
|
have at least GStreamer 1.14 and gst-plugins-base 1.14 installed. In addition,
|
||||||
|
some of the examples/tutorials require various GStreamer plugins to be
|
||||||
|
available, which can be found in gst-plugins-base, gst-plugins-good,
|
||||||
|
gst-plugins-bad, gst-plugins-ugly and/or gst-libav.
|
||||||
|
|
||||||
|
<a name="installation-linux"/>
|
||||||
|
|
||||||
|
### Linux/BSDs
|
||||||
|
|
||||||
|
You need to install the above mentioned packages with your distributions
|
||||||
|
package manager, or build them from source.
|
||||||
|
|
||||||
|
On Debian/Ubuntu they can be installed with
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev \
|
||||||
|
gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
|
||||||
|
gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \
|
||||||
|
gstreamer1.0-libav libgstrtspserver-1.0-dev libges-1.0-dev
|
||||||
|
```
|
||||||
|
|
||||||
|
The minimum required version of the above libraries is >= 1.14. If you
|
||||||
|
build the gstreamer-player sub-crate, or any of the examples that
|
||||||
|
depend on gstreamer-player, you must ensure that in addition to the above
|
||||||
|
packages, `libgstreamer-plugins-bad1.0-dev` is installed. See the `Cargo.toml`
|
||||||
|
files for the full details,
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ apt-get install libgstreamer-plugins-bad1.0-dev
|
||||||
|
```
|
||||||
|
|
||||||
|
Package names on other distributions should be similar.
|
||||||
|
Please submit a pull request with instructions for yours.
|
||||||
|
|
||||||
|
<a name="installation-macos"/>
|
||||||
|
|
||||||
|
### macOS
|
||||||
|
|
||||||
|
You can install GStreamer and the plugins via [Homebrew](https://brew.sh/) or
|
||||||
|
by installing the [binaries](https://gstreamer.freedesktop.org/data/pkg/osx/)
|
||||||
|
provided by the GStreamer project.
|
||||||
|
|
||||||
|
We recommend using the official GStreamer binaries over Homebrew, especially
|
||||||
|
as GStreamer in Homebrew is [currently broken](https://github.com/orgs/Homebrew/discussions/3740#discussioncomment-3804964).
|
||||||
|
|
||||||
|
#### GStreamer Binaries
|
||||||
|
|
||||||
|
You need to download the *two* `.pkg` files from the GStreamer website and
|
||||||
|
install them, e.g. `gstreamer-1.0-1.20.4-universal.pkg` and
|
||||||
|
`gstreamer-1.0-devel-1.20.4-universal.pkg`.
|
||||||
|
|
||||||
|
After installation, you also need to set the `PATH` environment variable as
|
||||||
|
follows
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ export PATH="/Library/Frameworks/GStreamer.framework/Versions/1.0/bin${PATH:+:$PATH}"
|
||||||
|
```
|
||||||
|
|
||||||
|
Also note that the `pkg-config` from GStreamer should be the first one in
|
||||||
|
the `PATH` as other versions have all kinds of quirks that will cause
|
||||||
|
problems.
|
||||||
|
|
||||||
|
#### Homebrew
|
||||||
|
|
||||||
|
Homebrew only installs various plugins if explicitly enabled, so some extra
|
||||||
|
`--with-*` flags may be required.
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ brew install gstreamer gst-plugins-base gst-plugins-good \
|
||||||
|
gst-plugins-bad gst-plugins-ugly gst-libav gst-rtsp-server \
|
||||||
|
gst-editing-services --with-orc --with-libogg --with-opus \
|
||||||
|
--with-pango --with-theora --with-libvorbis --with-libvpx \
|
||||||
|
--enable-gtk3
|
||||||
|
```
|
||||||
|
|
||||||
|
Make sure the version of these libraries is >= 1.14.
|
||||||
|
|
||||||
|
<a name="installation-windows"/>
|
||||||
|
|
||||||
|
### Windows
|
||||||
|
|
||||||
|
You can install GStreamer and the plugins via [MSYS2](http://www.msys2.org/)
|
||||||
|
with `pacman` or by installing the
|
||||||
|
[binaries](https://gstreamer.freedesktop.org/data/pkg/windows/) provided by
|
||||||
|
the GStreamer project.
|
||||||
|
|
||||||
|
We recommend using the official GStreamer binaries over MSYS2.
|
||||||
|
|
||||||
|
#### GStreamer Binaries
|
||||||
|
|
||||||
|
You need to download the *two* `.msi` files for your platform from the
|
||||||
|
GStreamer website and install them, e.g. `gstreamer-1.0-x86_64-1.20.4.msi` and
|
||||||
|
`gstreamer-1.0-devel-x86_64-1.20.4.msi`. Make sure to select the version that
|
||||||
|
matches your Rust toolchain, i.e. MinGW or MSVC.
|
||||||
|
|
||||||
|
After installation set the ``PATH` environment variable as follows:
|
||||||
|
|
||||||
|
```console
|
||||||
|
# For a UNIX-style shell:
|
||||||
|
$ export PATH="c:/gstreamer/1.0/msvc_x86_64/bin${PATH:+:$PATH}"
|
||||||
|
|
||||||
|
# For cmd.exe:
|
||||||
|
$ set PATH=C:\gstreamer\1.0\msvc_x86_64\bin;%PATH%
|
||||||
|
```
|
||||||
|
|
||||||
|
Make sure to update the path to where you have actually installed GStreamer
|
||||||
|
and for the corresponding toolchain.
|
||||||
|
|
||||||
|
Also note that the `pkg-config.exe` from GStreamer should be the first one in
|
||||||
|
the `PATH` as other versions have all kinds of quirks that will cause
|
||||||
|
problems.
|
||||||
|
|
||||||
|
#### MSYS2 / pacman
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ pacman -S glib2-devel pkg-config \
|
||||||
|
mingw-w64-x86_64-gstreamer mingw-w64-x86_64-gst-plugins-base \
|
||||||
|
mingw-w64-x86_64-gst-plugins-good mingw-w64-x86_64-gst-plugins-bad \
|
||||||
|
mingw-w64-x86_64-gst-plugins-ugly mingw-w64-x86_64-gst-libav \
|
||||||
|
mingw-w64-x86_64-gst-rtsp-server
|
||||||
|
```
|
||||||
|
|
||||||
|
Make sure the version of these libraries is >= 1.14.
|
||||||
|
|
||||||
|
Note that the version of `pkg-config` included in `MSYS2` is
|
||||||
|
[known to have problems](https://github.com/rust-lang/pkg-config-rs/issues/51#issuecomment-346300858)
|
||||||
|
compiling GStreamer, so you may need to install another version. One option
|
||||||
|
would be [`pkg-config-lite`](https://sourceforge.net/projects/pkgconfiglite/).

||||||

<a name="getting-started"/>
|
||||||
|
|
||||||
|
## Getting Started
|
||||||
|
|
||||||
|
The API reference can be found
|
||||||
|
[here](https://gstreamer.pages.freedesktop.org/gstreamer-rs/stable/latest/docs/gstreamer/), however it is
|
||||||
|
only the Rust API reference and does not explain any of the concepts.
|
||||||
|
|
||||||
|
For getting started with GStreamer development, the best would be to follow
|
||||||
|
the [documentation](https://gstreamer.freedesktop.org/documentation/) on the
|
||||||
|
GStreamer website, especially the [Application Development
|
||||||
|
Manual](https://gstreamer.freedesktop.org/documentation/application-development/).
|
||||||
|
While being C-centric, it explains all the fundamental concepts of GStreamer
|
||||||
|
and the code examples should be relatively easily translatable to Rust. The
|
||||||
|
API is basically the same, function/struct names are the same and everything
|
||||||
|
is only more convenient (hopefully) and safer.
|
||||||
|
|
||||||
|
In addition there are
|
||||||
|
[tutorials](https://gstreamer.freedesktop.org/documentation/tutorials/) on the
|
||||||
|
GStreamer website. Many of them were ported to Rust already and the code can
|
||||||
|
be found in the
|
||||||
|
[tutorials](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/tree/main/tutorials)
|
||||||
|
directory.
|
||||||
|
|
||||||
|
Some further examples for various aspects of GStreamer and how to use it from
|
||||||
|
Rust can be found in the
|
||||||
|
[examples](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/tree/main/examples)
|
||||||
|
directory.
|
||||||
|
|
||||||
|
Various GStreamer plugins written in Rust can be found in the
|
||||||
|
[gst-plugins-rs](https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs)
|
||||||
|
repository.
