mplayer jekry performace if not root

tytus

The only time I get an acceptable performance form mplayer is when I run it as root. If I run it as non-root user the vidoe is jerky and freezes quite often. Is there anything that I can do to get acceptable performance form mplayer run as non-root?

Give us some more information, your post is too vague... could you give me output of what mplayer says when it starts up as your 'jerky' user?

Maybe you have no read access to /dev/rtc ? Did you add your user to the video group (I don't actually know whether that does anything, but adding yourself to the audio group gives you audio, so I did it anyway, maybe...)

Hm, can't see anything out of the ordinary... Maybe you have restrictions on your videocard, but being in the videogroup should solve that...

About RTC, some people say it doesn't make a difference for them, some do. It is not your problem, because you don't have it compiled, and as root you play fine.

You haven't by any chance fiddled with the /etc/security/limits.conf file, and renicing your processes? That might cause trouble (it's a long shot, but hey

).

A little less desperate action might be to move your .mplayer directory (in your home) to another name, so mplayer will make a standard new one. It might be getting some deprecated options from there, that don't work or are suboptimal for your machine (maybe from an old release). I have .mplayer_old[1-4] directories, so I can tell you: it sometimes works

Guess what... This solved the problem! I run diff between the old
.mplayer and the new one and here is the output (it may help
somebody):

hah, that explains it, cache on 128 is way too low... standard it's on 4096 I think.
Glad to be on the helping side for a change
