Quickly looking at mp4 muxer code, it only asks 2 blocks to be in fifo
so it can calculate block length.

I think that in mp4 case it's enough if dts is incrementing within track
and it doesn't need to be interleaved according to dts along all tracks
(but I didn't check this yet).

But yes you have good point, and it would be nice to have sample that
has that kinda es that disappears for certain time.

Yep, all other muxers seem to ask just if there is any packet in fifos.
