Let me guess, you use ctrl-c to quit, right? This will cause ffmux_mp4
to not write headers (which is done on end-of-stream), and thus the file
will effectively be garbage.

Use a finite sound source that properly introduces end-of-stream, like a
file or a sinesrc that emits EOS after a while. The resulting file will
play fine.
