Comment (by mkver):
The H.264 track in your input file isn't in annex B format, but in mp4
format. So are the extradata. The thing is that the format of the
mp4-style extradata is different from the format that is used at the mp4
sample level; in other words, the output of the dump_extra bitstream
filter is a totally invalid stream. Use the h264_mp4toannexb bitstream
filter before dump_extra.
