gstreamer-rs 
GStreamer (Video library) bindings for Rust. Documentation can be found here.
These bindings are providing a safe API that can be used to interface with GStreamer, e.g. for writing GStreamer-based applications.
For background and motivation, see the announcement blogpost.
The bindings (since 0.8.0) are autogenerated with gir based on the GObject-Introspection API metadata provided by the GStreamer project. Older versions before 0.8.0 were manually written and the repository can be found here. The API of the two is incompatible.
A crate for writing GStreamer plugins in Rust can be found here: https://github.com/sdroege/gst-plugin-rs
Table of Contents
Installation
To build the GStreamer bindings or anything depending on them, you need to have at least GStreamer 1.8 and gst-plugins-base 1.8 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.
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
$ 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
Package names on other distributions should be similar. Please submit a pull request with instructions for yours.
macOS
You can install GStreamer and the plugins via Homebrew or by installing the binaries provided by the GStreamer project.
Homebrew
$ brew install gstreamer gst-plugins-base gst-plugins-good \
gst-plugins-bad gst-plugins-ugly gst-libav
GStreamer Binaries
You need to download the two .pkg files from the GStreamer website and
install them, e.g. gstreamer-1.0-1.12.3-x86_64.pkg and
gstreamer-1.0-devel-1.12.3-x86_64.pkg.
After installation, you also need to install pkg-config (e.g. via Homebrew)
and set the PKG_CONFIG_PATH environment variable
$ export PKG_CONFIG_PATH="/Frameworks/GStreamer.framework/Versions/Current/lib/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"
Windows
You can install GStreamer and the plugins via MSYS2
with pacman or by installing the
binaries provided by
the GStreamer project.
MSYS2 / pacman
$ pacman -S 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
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_64-1.12.3.msi and
gstreamer-1.0-devel-x86_64-1.12.3.msi.
After installation, you also need to install pkg-config (e.g. via MSYS2 or
from here)
and set the PKG_CONFIG_PATH environment variable
$ export PKG_CONFIG_PATH="c:\\gstreamer\\1.0\\x86_64\\lib\\pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"
Getting Started
The API reference can be found here, 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 on the GStreamer website, especially the Application Development Manual. 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 on the GStreamer website. Many of them were ported to Rust already and the code can be found in the tutorials directory.
Some further examples for various aspects of GStreamer and how to use it from Rust can be found in the examples directory.
