--- Comment #1 from Christian König deathsimple@vodafone.de --- Video works perfectly on my 7870.

Are you sure that's not an unrelated bug?

Please try running it without any desktop effects. Best way to narrow it down would be a pure X server without anything else started.

This is my pure X server so I fear it's not going to happen. Anyway I just got two more crashes with KDE (one with desktop effects ON and one with desktop effects OFF) and then it worked for a couple of times. Anyway it's way too slow (I get "Your system is too SLOW to play this!" in mplayer).

--- Comment #3 from darkbasic darkbasic@linuxsystems.it --- I switched from libav/mplayer2 to ffmpeg/mplayer git and the crash seems gone. Bye bye libav.

Being stable I did some more tests and unfortunately performance sucks so I renamed the bug report.

Benchmarking the video output: ffh264 software decoder + gl/xv/vdpau

~ $ mplayer -benchmark -nosound -lavdopts threads=16 PlanetEarthBirds.mkv -vo gl

BENCHMARKs: VC: 3.403s VO: 7.530s A: 0.000s Sys: 0.672s = 11.605s BENCHMARK%: VC: 29.3238% VO: 64.8892% A: 0.0000% Sys: 5.7870% = 100.0000%

~ $ mplayer -benchmark -nosound -lavdopts threads=16 PlanetEarthBirds.mkv -vo xv

BENCHMARKs: VC: 7.878s VO: 2.162s A: 0.000s Sys: 1.040s = 11.080s BENCHMARK%: VC: 71.0951% VO: 19.5154% A: 0.0000% Sys: 9.3896% = 100.0000%

~ $ mplayer -benchmark -nosound -lavdopts threads=16 PlanetEarthBirds.mkv -vo vdpau

BENCHMARKs: VC: 0.863s VO: 43.888s A: 0.000s Sys: 0.550s = 45.300s BENCHMARK%: VC: 1.9042% VO: 96.8823% A: 0.0000% Sys: 1.2135% = 100.0000%

With both -vo gl and -vo xv it took ~11.080s while with -vo vdpau it took 45.300s. -vo vdpau is *4x* slower.

Benchmarking the video decoder: ffh264/ffh264vdpau + vo null

~ $ mplayer -benchmark -nosound -lavdopts threads=16 PlanetEarthBirds.mkv -vo null

BENCHMARKs: VC: 8.855s VO: 0.002s A: 0.000s Sys: 0.493s = 9.350s BENCHMARK%: VC: 94.7024% VO: 0.0262% A: 0.0000% Sys: 5.2714% = 100.0000%

~ $ mplayer -benchmark -nosound PlanetEarthBirds.mkv -vo null -vc ffh264vdpau

It seems I can't use the null video output with the hardware decoder ffh264vdpau: I get tons of "Too many buffered pts". It does support only -vo vdpau, not even xv or gl. Such a pity. (is it a known limitation/bug?)

Let's do a more complete benchmark: ffh264+xv vs ffh264vdpau+vdpau

We already saw ffh264+xv took 11.080s, let's see how ffh264vdpau+vdpau performs.

~ $ mplayer -benchmark -nosound PlanetEarthBirds.mkv -vo vdpau -vc ffh264vdpau

BENCHMARKs: VC: 0.869s VO: 44.581s A: 0.000s Sys: 0.374s = 45.824s BENCHMARK%: VC: 1.8955% VO: 97.2876% A: 0.0000% Sys: 0.8169% = 100.0000%

As expected it's still 4 times slower because the bottleneck is obviously the vdpau video output and not the ffh264vdpau decoder.

Being 4x slower vdpau is completely useless right now :( Please note that I disabled desktop compositing before doing the tests.

...

Is it fixed in 3.16-rc6?

That fix should be in all kernels since 3.14. It was named "drm/radeon: fix UVD IRQ support on SI".

--- Comment #10 from Andy Furniss adf.lists@gmail.com --- That looks normal, I have that sample and it's 1444 frames / 60Hz = 24 seconds.

You can't really turn off vsync for vdpau and mplayer doesn't do gl interop.

Cpu times can mislead if cpufreq on_demand is in use as you don't know what freq the cores are in.

UVD/powerplay is tuned for playback (at least on recent GPUs) if using with eg. ffmpeg you can get more perf by forcing GPU clocks to high.
