A NVIDIA VDPAU Back-End For Intel's VA-API

"Gwenole Beauchesne is the developer working for Splitted Desktop Systems who had written the VA-API patches back in December for MPlayer and FFmpeg. However, his latest Video Acceleration API hacking has led him to write a VDPAU back-end for VA-API. By allowing VDPAU (the Video Decode and Presentation API for Unix) to operate underneath VA-API, it's now possible for video playback to be accelerated using VA-API on NVIDIA hardware. NVIDIA had introduced VDPAU to their drivers last year in order to bring PureVideo features to Linux. Our VDPAU benchmarks very pleasing with the ability to use a $20 CPU and $30 GPU to play HD videos with ease. This NVIDIA API has already worked its way into the code for MPlayer, FFmpeg, MythTV, Xine, and support for VLC is underway."
