Here's the problem: the lavc encoder is getting reinitialized in the
middle of the encode due to changing header properties in the source
file. Try using lavc for decoding (-vc ffmpeg12) and see if the
problem goes away. This is a bug that needs to be fixed, but I don't
know enough to deal with it.
