Hi,
Thanks for your tips. I tried them, but unfortunately my ipod still
refuses to play the video...
The commands I used were:
mencoder $INFILE -sws 9 -of avi -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=300 -o /tmp/$INFILE_$$ -oac faac -vf
scale=320:-2,expand=320:240:0:0:1::,harddup -faacopts
mpeg=4:br=128:object=2 -srate 44100 -channels 2 -sub $SUBS -subalign 0
-subpos 75 -ofps 25 -ffourcc XVID -noodml
MP4Box -aviraw video /tmp/$INFILE_$$
MP4Box -aviraw audio /tmp/$INFILE_$$
mv /tmp/$INFILE_$$_audio.raw /tmp/$INFILE_$$_audio.aac
MP4Box -fps 25 -add /tmp/$INFILE_$$_video.cmp -add
/tmp/$INFILE_$$_audio.aac -ipod -mpeg4 -new $OUTFILE
mp4creator -list $OUTFILE
rm -f /tmp/$INFILE_$$*
I also tried the DX50 instead of XVID. The output text is attached as a
text file, with "..." whenever it was printing progress info. I have no
clue why my ipod isn't happy...

Sebastiaan
