Good idea, will do.

You mean because the codec in ASF/RM could be h264? I don't thnk it
leads to conflicts, don't forget that if there is a dynamic payload
handler, its s->parse_packet func will always be used before any
generic functions in rtp_parse_packet(). This will always work. ASF
does use the RTP headers in the end, so calling rtp_parse_packet() for
barsing of these bits is OK. RM doesn't use this codepath at all (it
uses ff_rdt_parse_packet()), so no worries there either.
Anyway, I might be wrong of course, but if I am, we'll see bugs coming
in at some point. :-). No bugs, then it probably works. (Don't take
this wrong, I have some outstanding bugs and missing features in the
ASF/RDT code, but these are relatively minor.)
