# gstreamer-rs [](https://crates.io/crates/gstreamer-allocators) [](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/commits/main)
|
||||
|
||||
[GStreamer](https://gstreamer.freedesktop.org/) (Allocators library) bindings for Rust.
|
||||
Documentation can be found [here](https://gstreamer.pages.freedesktop.org/gstreamer-rs/stable/latest/docs/gstreamer_allocators/).
|
||||
|
||||
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 1.8 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.
|
||||
|
||||
<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 >= 1.8. 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 and
|
||||
that the version is >= 1.12. See the `Cargo.toml` files for the full
|
||||
details,
|
||||
|
||||
```console
|
||||
$ # Only if you wish to install gstreamer-player, make sure the version
|
||||
$ # of this package is >= 1.12.
|
||||
$ 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.
|
||||
|
||||
#### 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
|
||||
```
|
||||
|
||||
If you wish to install the gstreamer-player sub-crate, make sure the
|
||||
version of these libraries is >= 1.12. Otherwise, a version >= 1.8 is
|
||||
sufficient.
|
||||
|
||||
#### 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
|
||||
|
||||
```console
|
||||
$ export PKG_CONFIG_PATH="/Library/Frameworks/GStreamer.framework/Versions/Current/lib/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"
|
||||
```
|
||||
|
||||
<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.
|
||||
|
||||
#### 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
|
||||
```
|
||||
|
||||
If you wish to install the gstreamer-player sub-crate, make sure the
|
||||
version of these libraries is >= 1.12. Otherwise, a version >= 1.8 is
|
||||
sufficient.
|
||||
|
||||
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/).
|
||||
|
||||
#### 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](https://sourceforge.net/projects/pkgconfiglite/))
|
||||
and set the `PKG_CONFIG_PATH` environment variable
|
||||
|
||||
```console
|
||||
$ export PKG_CONFIG_PATH="c:\\gstreamer\\1.0\\x86_64\\lib\\pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"
|
||||
```
|
||||
|
||||
<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 [](https://crates.io/crates/gstreamer-allocators-sys) [](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/commits/main)
|
||||
|
||||
[GStreamer](https://gstreamer.freedesktop.org/) (Allocators 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.
