[MPlayer-users] Excessive * audio codec cpu usage

[Arpi]

Hi,

hmm. i think it won't show any valid values if other processes with high cpu
usage are running at the same time (like mencoder).

it emasures real time (not process time) and if the decoding process is
interrupted by scheduler and the other process work for some time, it will
look like the decoder eat that cpu...

i don't know any method to measure only the process' cpu time.
