Where can I find the patch? (a link to ml archives would be ok).
I should not comment before reading the actual patch, but...
Judging from the comments above, I suspect this increases again the
confusion in the rtp demuxer: currently, the rtp demuxer is not supposed
to return a full frame, but uses a "parser" provided by libavcodec to
split the stream in frames. If I understand correctly what you wrote
above, your patch is changing this behaviour, but only for some payloads...
