It was just a month ago that NVIDIA had introduced the Video Decode and Presentation API for Unix
that brought PureVideo-like features to Linux
and as our early benchmarks showed
this video API did an effective job at offloading video-related tasks to the graphics card that otherwise would be handled by the CPU. Last week we then took a $20 processor and $30 graphics card and managed to play HD videos on Linux
quite well when using VDPAU.
When NVIDIA had introduced VDPAU they did supply patches that added support for this API to the MPlayer
projects. The open-source community came along and provided VDPAU support for MythTV
late last month. This work done entirely outside of NVIDIA ended up working out quite well and now MythTV
takes full advantage of this NVIDIA creation.
The Xine community has now come along, however, and created their own VDPAU support. This Xine VDPAU implementation doesn't depend upon ffmpeg and currently supports H.264 and MPEG streams with OSD (On-Screen Displays) and de-interlacing also working.
Currently to take advantage of VDPAU with Xine you'll need to checkout the latest code from their Subversion repository and be using the NVIDIA 180.16 driver
or later. Additional information on the Xine video player is available from their web-site
While VDPAU continues to be adopted by different media players and users have been experiencing great results, AMD's competitor, which will be called X-Video Bitstream Acceleration
, still has yet to see the light of day.
