[GStreamer](https://gstreamer.freedesktop.org/) (RTSP library) bindings for Rust.
2022-02-03 21:51:10 +00:00
Documentation can be found [here](https://gstreamer.pages.freedesktop.org/gstreamer-rs/stable/latest/docs/gstreamer_rtsp/).
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/).

## 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.
