To clarify, I meant the _internal_ format we would use within ffmpeg.
Module loaders imho cannot be represented within the existing
demuxers+decoders framework. So we would (possibly) have loaders which
fill an AVModule/AVPattern/whatever, defined functions which extract
(and maybe unpack) pattern data and feed the renderer, manage
instrument/sample data etc. And of course reusing code where
