[arch-general] 1080p playback
Greetings everyone, I've been having some issues playing 1080p movies, performance wise. I have a 8800GTS, the 640MB one, and a Core 2 Duo 6600 running at 2,4GHz. By default, with the regular mplayer, it uses 50% of the CPU (100% of one core?) and after a while the movie starts lagging, desynchronizing video/sound. If I seek forward or back the sync gets fixed so I'm guessing it's not the movie's fault. I tried installing mplayer-vdpau-nogui from AUR. The installation ended with some problems, but it was compiled. I found it under /var/aur/something and tried running ./mplayer -vo help but vdpau wasn't listed there. Wikipedia [1] says vdpau supports 8800GTS 640, but several other places says it doesn't. This card has VP1, so, from what I read, at least a part of the processing can be put on it, wonder if vdpau will ever support it. If vdpau really doesn't support it, is there a way for me to watch 1080p movies on my machine? Maybe some kind of patch to mplayer that makes it use both cores or something... Thanks in advance, Best regards, Paulo Santos [1] http://en.wikipedia.org/wiki/VDPAU

No need to patch mplayer for that. Try using: mplayer -lavdopts fast:skiploopfilter=nonkey:threads=2 -- Pierre 'catwell' Chapuis

8800GTS 640mb has a G80 core and doesnt support VDPAU accelleration, the G92 core which comes with the 512 varients does.

And it won't ever support it? It's a shame that such a good card can't be used for at least a bit of processing. I haven't tried Pierre's advice yet (thank you, by the way) because somehow I screwed up my mplayer. Once I get it to work again I'll give some feedback. I must be able to play 1080p on this kind of computer or I'll cry. It's only 2,5 years old. Best regards and thanks for the replies, Paulo Santos

I can play 1080p on my athlon 64 3200 as long as im not doing anything else. Its a shame, I have the same card.

It does! I can play 1080p (H264, mkv) on my old macbook (core2duo @ 2ghz) with no hardware acceleration. I'm using the parallel version of ffmpeg h264 decoder.
Greetings, I managed to get it to work, thanks to your tips. Following the instructions in MPlayer's website [1], I built mplayer with ffmpeg-mt (multi-threaded ffmpeg). Playing 1080p movies with two threads (-lavdopts threads=2) they play as smooth as they can get. Meaning that even without a vdpau compatible card, a decent enough CPU (2,4 GHz in my case) plays 1080p without cutting down on quality.

Does that mean I'd be able to watch 1080p movies on my Intel Centrino Duo 1,86Ghz + Intel GMA950? I can watch 720p without problems now, but when it comes to 1080p... the thing is impossible
