Release notes for
The GStreamer team is pleased to announce the first release of the unstable
1.7 release series. The 1.7 release series is adding new features on top of
the 1.0, 1.2, 1.4 and 1.6 series and is part of the API and ABI-stable 1.x release
series of the GStreamer multimedia framework. The unstable 1.7 release series
will lead to the stable 1.8 release series in the next weeks. Any newly added
API can still change until that point.
Binaries for Android, iOS, Mac OS X and Windows will be provided separately
during the unstable 1.7 release series.
This module, gstreamer, only contains core functionality.
For actual media playback, you will need other modules.
- contains a basic set of well-supported plugins
- contains a set of well-supported plugins under our preferred license
- contains a set of well-supported plugins, but might pose problems for
- contains a set of less supported plugins that haven't passed the
rigorous quality testing we expect, or are still missing documentation
and/or unit tests
- contains a set of codecs plugins based on libav (formerly gst-ffmpeg)
