Ok; this afternoon I'll try to have a look at passing a ByteIOContext as an
argument (but first I have to understand why this can simplify things ;-).

BTW, you said that you also found other muxers with the same problem...
Can you post the list of such muxers (or the grep command you used)
somewhere? (in a roundup issue, or something)
In this way, the information does not get lost, and people searching for
some way to help can find a list of issues to fix.
