Oh, sorry. I now see that the issue is that without a PAT/PMT
MPlayer will fallback to assuming it contains MP2 audio,
though it really is AAC.
So the real issue is that libmad decoder fails in bad ways
that cause hangs instead of e.g. just silence.
Not sure this is specific to libmad actually though, so not
sure how easy that would be to fix (and maybe not worth it).
