Release notes for GStreamer 1.3.3

The GStreamer team is pleased to announce the third release of the unstable 1.3 release series. The 1.3 release series is adding new features on top of the 1.0 and 1.2 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework. The unstable 1.3 release series will lead to the stable 1.4 release series in the next weeks, and newly added API can still change until that point.

This is hopefully the last 1.3 development release and will be followed by the first 1.4.0 release candidate (1.3.90) in 1-2 weeks. Which then hopefully is followed by 1.4.0 soonish in early July.

Binaries for Android, iOS, Mac OS X and Windows will be provided separately during the unstable 1.3 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 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)
