[Mplayer-dvb] mplayer playback through dvb takes 100% cpu time

[Soeren Sonnenburg]

Hi.

I noticed a weirdness with mplayer and -vo mpegpes playback. If I don't
also use -ao mpegpes the CPU load goes up to 100% instead of like 10%,
i.e. both 

mplayer -ao mpegpes -vo mpegpes <file>
and 
mplayer -nosound -vo mpegpes <file> 

both take like 10% CPU but, 

mplayer -ao null -vo mpegpes <file>
or
mplayer -ao alsa9 -vo mpegpes <file>

eat up all CPU there is but plays (of course gives frame drops)

Is anyone else observing this or even better knows the cause of it ?

Soeren.
