[MEncoder-users] mpeg4 encoding problem

[Gerog Vits]

Hello!

Thank you for helping the clueless!
I have noticed this with pre5, pre6 and pre7 all
compiled from source.
My current kernel is 2.6.6.

I am using the following to capture:

nice -n -10 \
mencoder tv:// -tv \
driver=v4l2:device=/dev/video0:normid=0:input=0:freq=$(channel
"$1"):fps=25:width=720:height=576:alsa:adevice=hw.0,0
\
-oac mp3lame -lameopts cbr:br=128 \
-ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=5000:keyint=125:mbd=2 \
-endpos $2:$3:00 -o "$4" \
2>/mnt/archiv/tvrec/tvreclog.txt 1>/dev/null

This is the playback & errout.
I used -quiet, -speed, -nosound and -vo null to
quickly get the output without watching the whole
movie again. The error messages are the same as
watching in the normal way.
