All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
## [0.8.0] - 2017-08-31

(< 0.8.0) of the bindings can be found [here](https://github.com/arturoc/gstreamer1.0-rs).
The API of the two is incompatible.

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

# gstreamer-rs [![crates.io](https://img.shields.io/crates/v/gstreamer-app.svg)](https://crates.io/crates/gstreamer-app) [![Build Status](https://travis-ci.org/sdroege/gstreamer-rs.svg?branch=master)](https://travis-ci.org/sdroege/gstreamer-rs)
[GStreamer](https://gstreamer.freedesktop.org/) (Base library) bindings for Rust.
Documentation can be found [here](https://sdroege.github.io/rustdoc/gstreamer/gstreamer/).
These bindings are providing a safe API that can be used to interface with
GStreamer, e.g. for writing GStreamer-based applications.
For background and motivation, see the [announcement blogpost](https://coaxion.net/blog/2017/07/writing-gstreamer-applications-in-rust/).
The bindings (since 0.8.0) 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. Older versions before 0.8.0 were manually
written and the repository can be found [here](https://github.com/arturoc/gstreamer1.0-rs).
The API of the two is incompatible.
A crate for writing GStreamer plugins in Rust can be found here: https://github.com/sdroege/gst-plugin-rs
