[License](#license) +1. [Contribution](#contribution) + + + +## 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 +``` + +The minimum required version of the above libraries is >= 1.14. See +the `Cargo.toml` files for the full details, + +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. + +``` +$ 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 +``` + +Please, make sure the version of these libraries is >= 1.14. + +#### GStreamer Binaries + +You need to download the *two* `.pkg` files from the GStreamer website and +install them, e.g. `gstreamer-1.0-1.14.4-x86_64.pkg` and +`gstreamer-1.0-devel-1.14.4-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="/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 + +``` +$ 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 \ + mingw-w64-x86_64-gst-rtsp-server +``` + +Please, make sure the version of these libraries is >= 1.14. + +#### 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_64-1.14.4.msi` and +`gstreamer-1.0-devel-x86_64-1.14.4.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 + +``` +$ 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://slomo.pages.freedesktop.org/rustdocs/gstreamer/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. + +GStreamer itself is licensed under the Lesser General Public License version +2.1 or (at your option) any later version: +https://www.gnu.org/licenses/lgpl-2.1.html + + + +## Contribution + +Any kinds of contributions are welcome as a pull request. + +Unless you explicitly state otherwise, any contribution intentionally submitted +for inclusion in gstreamer-rs by you, as defined in the Apache-2.0 license, shall be +dual licensed as above, without any additional terms or conditions.
