Sorry, I should have included the command line I was using:

First, I encoded the PNGs into a RAW AVI using:

# mencoder -mf on:w=640:h=480:fps=25:type=png -ovc rawrgb -o raw.avi \*.png

That produces an AVI that is 200+ MB (as expected). Then I tried to use the
Huffman YUV encoder on that AVI using the command line:

# mencoder raw.avi -ovc lavc -lavcopts vcodec=huffyuv -o huff.avi

This fails. Below is the output I get. Any help would be great.

Thanks,

ARB

# mencoder raw.avi -ovc lavc -lavcopts vcodec=huffyuv -o huff.avi
