X-Video Bitstream Acceleration

X - Video Bitstream Acceleration ( XvBA ) is a proprietary programming interface for Radeon graphics card manufacturer AMD, on the decoding of video streams and post-processing of the decoded material can be largely shifted to Linux -based operating systems from the CPU to the graphics card (hardware acceleration).

By XvBA should be possible to outsource the following calculations to the graphics card: motion compensation, inverse discrete cosine transform and the Variable Length Coding with the video formats MPEG -2, MPEG -4 AVC ( H.264) and VC-1, AVC and VC-1 In addition, the deblocking.

Since November 2009 supports a proprietary driver named xvba video software with support for Video Acceleration API going to outsource about XvBA hardware acceleration for AMD Radeon graphics cards series.
