I have been rolling my own MythTV packages for a few months now, as the OpenGL paches made by Mark Kendall never got included in the official -fixes branch of mythtv. Now Jean-Yves Avenard has posted a VDPAU patch for MythTV 0.21-fixes on his site that in essence provides what PureVideo/DirectX Video Acceleration is on the Windows platform. He also provided a Ubuntu/Mythbuntu repository for all of us running that distribution. MythTV and mplayer with VDPAU support can be yours by using this repository. Add to /etc/apt/sources.list:
deb http://www.avenard.org/files/ubuntu-repos testing/
Ohh, this is very much NON TESTED. Take it or leave it, but don’t complain on the official MythTV or Mythbuntu forums and mailing lists.
