§gstreamer-rs

GStreamer 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 and GStreamer plugins.

The bindings are mostly autogenerated with gir based on the GObject-Introspection 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.

§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 libgstrtspserver-1.0-dev libges-1.0-dev

On Fedora:

dnf install gstreamer1-devel gstreamer1-plugins-base-devel \
      gstreamer1-plugins-good gstreamer1-plugins-bad-free \
      gstreamer1-plugin-libav gstreamer1-rtsp-server-devel \
      gst-editing-services-devel

More Fedora packages are available in RPMFusion:

dnf install gstreamer1-plugins-bad-freeworld gstreamer1-plugins-ugly

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,

$ apt-get install libgstreamer-plugins-bad1.0-dev

On Fedora:

dnf install gstreamer1-plugins-bad-free-devel

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.

We recommend using the official GStreamer binaries over Homebrew, especially as GStreamer in Homebrew is currently broken.

§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

$ 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.

$ 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.

§Windows

You can install GStreamer and the plugins via MSYS2 with pacman or by installing the binaries 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:

# 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

$ 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 compiling GStreamer, so you may need to install another version. One option would be pkg-config-lite.

§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. The Rust APIs are annotated with #[doc(alias = "c_function_name")], so you can search for a C function name in this documentation and find the corresponding Rust binding.

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.

Various GStreamer plugins written in Rust can be found in the gst-plugins-rs repository.
