Release notes for GStreamer OpenMAX IL wrapper plugin 1.9.1

The GStreamer team is pleased to announce the first release of the unstable 1.9 release series. The 1.9 release series is adding new features on top of the 1.0, 1.2, 1.4, 1.6 and 1.8 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework. The unstable 1.9 release series will lead to the stable 1.10 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 in the next days.

This module contains a plugin that wraps available OpenMAX IL components and makes them available as standard GStreamer elements.

Other modules containing plugins are:

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
