yes, you are right - i can play 1080p h264 video just fine with -vo
vaapi:gl:tfp, with only 4-5% of CPU usage but when i use -vo vaapi:gl
i've got broken playback - like displaying a still frame for 3-4
seconds, the jumping through all this time to next frame, displaying
it again for 3-4 seconds and so on (cpu usage is still low).
FWIW, my system is a standard Ubuntu/lucid + the following patches:
<http://www.splitted-desktop.com/~gbeauchesne/libva/ironlake.patches/ubuntu.lucid/
>
And this worked fine here. I will try to have a better look.
XBMC
media center (that is using vaapi with ffmpeg) also plays video in a
broken way (mostly the same as described) and I thought I can
implement mplayer style TFP playback in XBMC as a temporary solution..
XBMC has another problem I reported, I also had a temporary fix but a
better one shouldn't be complicated either.
Just wanted to understand why mplayer explicit TFP usage option plays
perfectly while TFP solution in libva glx doesn't while the code looks
similar - is this because of extra FBO operations?.
Yes, the code is even similar with that of vdpau-video too. :) Though,
I need to update the libva-glx one with some other arrangements I made.
Regards,
Gwenole.
