.m4a != .aac. .m4a, afaik, is Quicktime/Apple's MPEG-4 AAC, which we
playback. .aac is actual raw MPEG-4 AAC. The metadata is probably
something id3v2-like. We don't playback this. I have a sample file, but
didn't look at it yet. We need to frame this before feeding it to the faad
plugin, because the faad plugin (unlike, for example, mad) expects
packeted data to be fed to it. It's that part that's missing/untested.
Maybe it works, but I suppose it doesn't. Quicktime packets data in the
container so that works automatically.
