Hello

I am new to this list, and here goes my problem report. I am running 
mencoder from shell on a dual PII, and I'm trying to use the 
multithreading with libavcodec. However, it doesn't seem to work as 
expected - in strace I see clone()'s, but neither top nor ps show new 
processes, and the whole work seems to still be done by only one thread  - 
again, judging by top.

Configuration: MPlayer-1.0pre5, Debian Sarge (pretty old), glibc 2.3.2, 
kernel 2.6.9, recording from a Hauppauge WinTV Express card. The command 
line looks like

mencoder tv:// -tv \
driver=v4l2:input=1:norm=pal:channel=108:chanlist=europe-west:width=320:\
height=240:outfmt=yuy2:device=/dev/video0:adevice=/dev/dsp:audiorate=32000:\
forceaudio:forcechan=1:buffersize=64 \
-ovc lavc -lavcopts threads=2:vcodec=mpeg4:vbitrate=1200:keyint=30 -oac \
mp3lame -lameopts br=128:cbr:mode=3:vol=8 -ffourcc divx -endpos 30 -o \
/video/test.avi

Which other information is needed?

Thanks
Guennadi
