# gstreamer-rs [![crates.io](https://img.shields.io/crates/v/gstreamer-rtp.svg)](https://crates.io/crates/gstreamer-rtp) [![pipeline status](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/badges/master/pipeline.svg)](https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/commits/master) [GStreamer](https://gstreamer.freedesktop.org/) bindings for Rust. Documentation can be found [here](https://gstreamer.pages.freedesktop.org/gstreamer-rs/stable/latest/docs/gstreamer_rtp/). 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. ## Table of Contents 1.

[Contribution](#contribution) ## 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 ```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. ### 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}" ``` ### 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}" ``` ## 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/master/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/master/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. ## LICENSE gstreamer-rs and all crates contained in here are licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option.
