-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm trying to watch Avatar (a rip from the BD that I made myself with makemkv) with mplayer. I have added a load of options to try to improve the playback quality, as it was extremely jerky and stuttering before - now it's watchable, but still not perfect. The command-line I use is: mplayer title00.mkv -channels 6 -vo vdpau -vc ffh264vdpau -lavdopts threads=3:skiploopfilter=all:fast I have disabled compositing in kwin - that makes a difference. I have tried using xv instead of vdpau, and the quality is virtually the same, which raises the question of whether vdpau is actually doing its job. The exact nature of the jerkiness is that it runs reasonably smoothly for about a second, then does a little freeze in the picture and jumps - all within about half a second. Sound remains smooth. This repeats. This is unnoticeable during most scenes, but really distracts you from the large, sweeping panoramic views. I am using mplayer from the Ubuntu Lucid repo - I will try the SVN if you think it might help. I am using pure ALSA as my sound output, but with a custom plugin that downmixes 5.1 surround to 4.0 (for my 4.0 surround system). I am pretty sure there is no interference from pulseaudio anywhere along the line. My CPU is an "Intel(R) Core(TM)2 Duo CPU E7300 @ 2.66GHz" My GPU is an "nVidia Corporation G96 [GeForce 9500 GT]" - actually branded PNY. I am using the proprietary nvidia driver from the Ubuntu Lucid repo - again, if there is a newer one and you think it might help, I'll try grabbing that. I have tried enabling the cache and framedrop, all making no difference. My monitor's resolution is somewhat lower than 1080p, so it has to scale the video down. However, even if I try to watch it fullsize (with some of it falling off the edge of the monitor obviously), it still jerks along. Playing lower-resolution films (though I have not tried any other h264 videos) does not exhibit this problem. I have not tried any other HD videos either. Anyone got any clue? Is my computer too poor to play it, or is it a software issue? If it's a hardware issue, do you think it's the GPU or the CPU that needs an upgrade? Thanks a lot, Muzer. - -- - -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GCS/CM/IT d>++ s+:- a--- C+++ UL+++>++++ P+>+++ L+++>+++++ E---->--- W+++ N o? K? w--- O+ M-- V- PS PE? Y-- PGP+++ t+ 5?
