It works, although not from the very first frame. It starts out of sync,
but then jumps, and then synchronizes more or

Please note that the two working methods shown in the Makefile have
severe disadvantages.
the first method (producing good.mp4) needs to decode and re-encode the
video, thus slow and loss of quality.
the second method (producing good2.mp4) needs to decode the video and
