Personally I believe we should better follow Baptiste's approach and
rewrite RM demuxer completely from scratch - current one is rather a
hack based on guesses before anything much was known about this format.

For example, there is such thing as interleaver. It tells demuxer how to
permute input data (like all those crazy swaps for sipro) but for now
it's completely ignored. Another thing is this multirate stuff. And yet
another thing is timestamps (and what they are good for anyway?).

But in lack of free time even such improvement as multirate support
would be extremely good.
