Please use mp4mux instead of ffmux_mp4. You should consider ffmux_m4
unsupported.

The problem also happens with mp4mux though. The reason is that the code only
knows how to put a track-number/track-count pair into an 'trkn' atom, but has
no fallback for when there's only a track number or only a track count.

Not sure if there's an official or inofficial way to pack only one of the two
values into that atom? (just set the other one to 0 maybe?)
