I wonder what code mp4creator uses. Theoretically I should've been
able to remux MP4 to MP4 using mp4creator exclusivelly. But as I said,
it extracted the video track from the MP4 and when I tried to merge it
in a new file it complained it's an unknown format. The very same
track it itself had extracted earlier. Go figure.
