Open Media Acceleration, a.k.a. OpenMAX, is the royalty-free set of programming interfaces for audio/video/image processing. OpenMAX is maintained by the Khronos Group and provides some similar functionality to video APIs like VDPAU and X-Video for hardware processing.
The new plug-in release by Collabora supports the stable GStreamer 1.x API/ABI with a generic OpenMAX IL implementation as well as special support for the OpenMAX features of the Raspberry Pi.
This release can work while being installed alongside the GStreamer 0.10.x series plug-in and new to this release is also supporting MPEG2 video files with OpenMAX.
More information on this OpenMAX IL Wrapper for the new stable GStreamer series can be found via the mailing list announcement.
