[MEncoder-users] Mencoder bug on ARM

[alesan at manoweb.com]

Hi, I have compiled mencoder on a linksys NSLU2 (200MHz ARM
CPU, 32MB ram, 500GB hdd). I tried to encode few pictures in
a video:

# mencoder mf://*.jpg -mf w=720:h=540:fps=25:type=jpg -ovc
lavc -lavcopts vcodec=mpeg4 -o test2.avi

Illegal instruction


How can I proceed to debug this? The same works ok on a
standard PC.
In few words, I would like to batch encode images from my
digital camera:
http://lnx.manoweb.com/wifi/webcam/
and automatically upload the "time-lapse" videos on the
internet. Until now I used a x86-64 pc:

Thank you
