Hi, gst-openmax is a GStreamer plug-in that allows communication with OpenMAX IL components. OpenMAX IL is an industry standard that provides an abstraction layer for computer graphics, video, and sound routines. It has been pushed specially by key industry players in embedded systems. After almost one year of development it's time for another pre-release (hopefully the last before the first release). The list of changes is huge, but I'll try to summarize them: * Massive stability improvements, specially while seeking and init/deinitalizing * Speech elements now actually work in real RTP calls * H.264 and AAC extradata handled properly * Error handling and safety checks implemented * A lot of code refactoring and cleanups * Improved unit tests * Many bug fixes Part of the old 'tunneling' branch has been merged, and another part has been rebased on top of the new master, however more work needs to be done. After the branch has been rebased, work on the code-style update can start, if GStreamer developers still wish to do that. A new official 'omap' (long-lived) branch has been created for Texas Intruments' OpenMAX IL implementation. The patches are distributed in the tarball. Also, there are patches to use gst-openmax on Android's OpenMAX IL implementation[1]. Work has been started to merge them into the master branch. [1] http://groups.google.com/group/prajnashi AFAIK the only thing missing for the first release is documentation, so I'll try to work on that, but maybe it can wait for 0.10.2, let's see. Thanks to all the people that contributed to the release. Tarballs can be found here: http://gstreamer.freedesktop.org/src/gst-openmax/pre/ Bugs resolved: * 548776: gstomx mpe4dec can not work with qtdemux * 569014: Dependency for check should be optional * 576114: omx_vorbisdec trumps oggdemux while accepting all applica... * 576499: build scripts use -Werror option, and build fails because...
