Catalyst 10.3 reports the XvMC extension to be present for my Radeon HD3200 GPU. Can I actually use it to decode MPEG2 or MPEG4 content? I tried by enabling xvmc decoder and output in MythTV but did not observe a notable decrease in CPU usage.
I failed to find relevant information on this in using the forum search, but I may have overlooked some bits.
And BTW, I do *not* want to use mplayer and any va-api tricks since I'm quite comfortable with MythTV's internal player (OSD, markers, overall integration).
I only know of mplayer and vlc (git) with vaapi support. xvmc should not really matter today as it only decodes mpeg2 and you will not see a diff when your cpu is not the slowest available. basically only for 1080p with bluray bitrates hw accelleration is a must have.
