No XVMC with 8500 and 100.14.03 Beta
I just purchased a brand new Gigabyte GeForce 8500GT for my home theatre PC. It didn't work under FC6 Linux with the 9755 drivers I had installed, so I was pleased to hear of the 100.14.03 Beta driver's release.
I installed the beta, and while things worked much better than with the "vesa" driver I had been using, XVMC doesn't seem to be available.
It looks good in the Xorg.0.log file:
(II) Loading extension XVideo
(II) Loading extension XVideo-MotionCompensation
But doesn't work with mythtv or mplayer (Here's the mplayer output):
mplayer -vo xvmc -vc ffmpeg12mc dvd://
VIDEO: MPEG2 720x480 (aspect 3) 29.970 fps 7500.0 kbps (937.5 kbyte/s)
vo_xvmc: X-Video extension 2.2
vo_xvmc: No X-Video MotionCompensation Extension on :0.0
Error opening/initializing the selected video_out (-vo) device.
The problem is specific to the 8500GT; I put my old 6800 nvidia card back in and xvmc worked again.
Unfortunately, I need xvmc for hdtv playback in mythtv, so it would be great if this got fixed..
