Description
This is a followup of:
http://ffmpeg.org/pipermail/libav-user/2012-February/001256.html
Running
ffmpeg -r 12 -i test-%04d.png -codec msmpeg4 -mbd rd test.avi
on the attached png file leads to a segfault.
A quick debugging session shows that an array index in ff_msmpeg4_encode_block becomes -1 at line 930 of msmpeg4.c (version 0.10)
