[MPlayer-users] Framedrop problem with VDPAU DI

[Dom H]

Ubuntu 10.04 LTS
gpu G210 + driver 285.05.09
mplayer from daily snapshot ppa
powermizer to max perf
compositing disabled



Playing back a BBC HD recording, if I set deint to 2 or 3 something
odd happens (deint=4 causes framedropping straight away as expected)
The video will play back smoothly

[h264_vdpau @ 0x89322a0]illegal short term buffer state detected
A:38769.3 V:38769.3 A-V: -0.000 ct: -1.005   0/  0  1% 39%  2.3% 1 0 50%

until it reaches a specific point in the video where the frames
dropped counter (3rd number from the end?) will suddenly start
increasing rapidly (~20/s) and the video starts to slow slightly and
audio will start to drift out of sync (even though A-V still says ~0)

AO: [pulse] 48000Hz 6ch floatle (4 bytes per sample) <- Adverts stop,
program starts and switches 2ch>5.1
A:38986.9 V:38986.9 A-V:  0.000 ct: -0.941   0/  0  0% 93%  1.9% 1621 0 50%

The thing is, if I seek (say 30s forward and then back again to just
after the point of the problem) sync is restored and the frame drop
counter stays at zero and everything carries on as normal until maybe
say 10mins time it happens again. I can seek back, sync will restore
and it will play the same section without dropping frames. It does
this 3-4 times over a 45min program. If the gpu can't handle deint=2/3
then I wouldn't expect seeking to fix the issue. Basically as soon as
1 frame is dropped, things spiral out of control, like some sort of
memory leak.
