# gstreamer-rs [![crates.io](https://img.shields.io/crates/v/gstreamer-app.svg)](https://crates.io/crates/gstreamer-app) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/badges/main/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/commits/main)
[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.

<a name="installation"/>
## 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.

# gstreamer-sys [![crates.io](https://img.shields.io/crates/v/gstreamer-app-sys.svg)](https://crates.io/crates/gstreamer-app-sys) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/badges/main/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/commits/main)
[GStreamer](https://gstreamer.freedesktop.org/) (App library) FFI bindings for Rust.
These bindings are providing unsafe FFI API that can be used to interface with
GStreamer. Generally they are meant to be used as the building block for
higher-level abstractions like:
* Bindings for GStreamer applications and plugins: https://gitlab.freedesktop.org/gstreamer/gstreamer-rs
* Various GStreamer plugins written in Rust: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
The bindings are 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.
