Description zippy 2015-07-05 01:18:02 UTC
if i boot with 'nouveau.debug=debug', VDPAU works flawlessly for all supported codecs. however, if i boot without it and try to play any video with VDPAU, my system slows down to a crawl. if i take too long to stop playback or to kill the offending program, i lose control of the system and i am forced to reboot.

i haven't experimented with other kernel parameters yet. any suggestions ?

GeForce 210
mesa 10.5.7
kernel 4.0.5

Is this a recent regression, or is this the first time you're trying it?
Comment 2 zippy 2015-07-05 04:49:12 UTC
the ctime on my firmware files is January 11, 2015, so it was around that time that i first got VDPAU to "work". nothing has changed since then, the behaviour is exactly the same.

i don't know if this is useful, but here is the difference in run times for debug on vs off, for a short mpeg2 video:

off (many dropped frames):
> time mplayer grb_2.mpg
real    0m40.529s
user    0m8.172s
sys     0m2.507s

on:
> time mplayer grb_2.mpg
real    0m32.866s
user    0m1.031s
sys     0m0.374s

i managed to play the full video with debug off without causing the system to become unresponsive.
