xvba-va-driver 0.7.8-1ubuntu3 (amd64 binary) in ubuntu vivid

 X-Video Bitstream Acceleration (XvBA), designed by AMD for its ATI/AMD Radeon
 GPU, is a future extension of the X video extension (Xv) for the X Window
 System on Linux operating-systems. XvBA API allows video programs to offload
 portions of the video decoding process to the GPU video-hardware. Currently,
 the portions designed to be offloaded by XvBA onto the GPU are motion
 compensation (mo comp) and inverse discrete cosine transform (iDCT), and VLD
 (Variable-Length Decoding) for MPEG-2, MPEG-4 AVC (H.264) and VC-1 encoded
 video.

 This driver only works with the proprietary fglrx driver from AMD.
