Release notes for GStreamer 1.1.4

The GStreamer team is proud to announce a new bug-fix release in the 1.x stable series of the core of the GStreamer streaming media framework.

The 1.x series is a stable series targeted at end users. It is not API or ABI compatible with the stable 0.10.x series. It is, however, parallel installable with the 0.10.x series and will not affect an existing 0.10.x installation.

The 1.x series has been reworked for more flexible memory handling, improved caps negotiation and re-negotiation, better handling of dynamic pipelines, and increased performance in general. It also features countless other feature additions and enhancements.

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)
