hi,
on my 12.04.1 ubuntu playing a .avi file in totem which contains XVID MPEG-4 uses between 50% and 70% for the process.
both cores show 50-70% cpu usage, somehow.
using mplayer cpu usage drops to 30% for the process below:
Code:
/usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
since this is a amd x2 cpu isnt that too much? or does mpeg-4 need this kind of processing power?
i just installed the ati/amd driver for the gfx card via the ubuntu drivers dialog.
snippet from Xorg.0.log, looks like its running:
