Public bug reported: Beginning with Ubuntu 14.04 mesa will be shipping with vdpau drivers that can be used by e.g. radeon / radeonsi OSS drivers. This allows low power systems, like AMD E350, Kabini and so on to playback Full HD h264, vc1, mpeg4 and mpeg2 videos.
Sady the wolrd is not only progressive. LiveTV is most of the time broadcasted as 1080i h264 or 576i mpeg2, which means, that it has to be deinterlaced after decoding. In current mesa vdpau (as is in 10.1) code only simple Bobbing [a] is implemented. This low quality method produces one full frame out of every field. This introduces flickering first and last line, when not taking care to cut those correctly. Grigori Goronzy (zgreg) has developed a high quality / state of the art Temporal deinterlacer [1][a] for mesa, which introduces far better quality than simple bobbing would do. This deinterlacer was already included into mesa master and was furthermore tested since more than 4 months via a special ppa in combination with xbmc [2]. This ppa was used by some thousand unique people. We would really like to see this deinterlacer in Ubuntu 14.04. This would make the new version a great basis for every htpc out there. I will attach the current patches, fetched via git format-patch out of mesa git tree.
