Actually this function is not really good:

If we have, say, video fragments whose duration is 2s, and audio
fragments whose duration is 3s, then demux will read more video
fragments (than audio ones) from the stream_filter module.

Other parts of the patch have to be changed as well to fix that issue.

I'm going to work on that but it's not trivial.
