Ok, I played several types of videos in xbmc today. h.264, mpeg2, xvid, 59.94p, 30fps, 29.97p, 29.97i, 23.97p.
I cannot get tearing to occur on the oss driver at all. And I have *vertical blank sync* - none. Playback is much better, only a few skips/judders, good av sync. I am happy with this.
Is *vertical blank sync* now obsolete/redundant on oss?
It took some digging to find a possible justified reason:
http://xorg.freedesktop.org/wiki/RadeonF.../#index2h2
anti-tearing flags- EnablePageFlip, SwapBuffers
in my xorg.0.log i have:
[ 24.996] (II) RADEON(0): KMS Pageflipping: enabled
[ 24.996] (II) RADEON(0): SwapBuffers wait for vsync: enabled
Prior to OSS, I had horrible tearing with this APU on fglrx. It was especially bad on youtube. Now with oss that is gone. Good riddens!
So isn't *vertical blank sync* - none, the correct choice for this mesa/oss driver?
