[MEncoder-users] Encoding in vp6 with vfw - floating point exception

[sentenza]

Hello,

I try to encode video with vp6 codec. My OS is linux Debian 3.1 and I use
mplayer  1.0pre7try2-3.3.5 version.

For this I use the folliwing command line :
# mencoder Corbeil-reportage-1.mov -o test.flv -vf scale=320:240 -ovc vfw
-v4wopts codec=vp6vfw.dll -oac mp3lame

To use vfw options I followed
http://thread.gmane.org/gmane.comp.video.mplayer.user/38781/focus
to use vfw options.
That's OK.

But when I encode I have a floating point exception.
Here is the mencoder output:
