Release notes for GStreamer 1.5.90

The GStreamer team is pleased to announce the first release candidate for the stable 1.6 release series. The 1.6 release series is adding new features on top of the 1.0, 1.2 and 1.4 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework. The final 1.6.0 release is planned in the next few days unless any major bugs are found.

Binaries for Android, iOS, Mac OS X and Windows will be provided separately by the GStreamer project.

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 distributors
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)
