This is only part of the problem, the real problem is that qtdemux thinks all
samples from the audio track have size=0.

The audio is DVI ADPCM and has the following properties:
samples per chunk = 1017
channels = 2
samples per frame = 30510
bytes per frame = 1024

And then it does:
(samples-per-chunk * channels) / samples-per-frame * bytes-per-frame

But samples-per-chunk * channels is much smaller than samples-per-frame, which
seems to indicate some issue in the way we are calculating those? Having the
bytes-per-frame multiplication before the division should lead to a non-zero
result but is it right? Anyone knows how DVI ADPCM should be packed into mov?
