What I meant was:
If you call melt (and valgrind) twice to produce two output files
from the same melt options (but different --malloc-fill) options,
are the output files different?
If not, the valgrind warning could be a false positive.

I don't know melt but from the debug output it looks as if your
ffmpeg command does something different (missing -vcodec
huffyuv?), no?
