When calling:

mencoder -lavdopts threads=8 -ofps 25 -ovc lavc -lavcopts vcodec=ffv1 -demuxer lavf -vfm ffmpeg -noskip -vf scale,format=i420 -forcedsubsonly -nosub -nosound "test.avi" -force-avi-aspect 1.81818 -of avi -o "ffv1Test.avi"

I get a lot of output:

[ffv1 @ 015e6f80]Provided packet is too small, needs to be 31555584

and at the end I get:

[ffv1 @ 015e6f80]Provided packet is too small, needs to be 31555584

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

The call should be correct, so I assume this is a bug of some sort.

Uploaded the test.avi I used in the call to:

and yes, I'm aware that in this case I could use ffmpeg with:
[code]ffmpeg -y -i "test.avi" -an -sn -threads 8 -vsync 0 -r 25000/1000 -pix_fmt yuv420p -vcodec ffv1 "ffv1Test.avi"code
