i want them documented then when i understand the code i can say if it
needs a cleanup.

its unfair to ask me to review additions to the mess called our rt*p code.
i cant make much sense of large parts of our rt*p code currently ...

do you have some code that can saftely be commited? i mean something
that doesnt interfere with the current code, that way others could work
on it too even if it does not work yet
this also reminds me about mans ts demuxer ...

i cant say anything here, its impossible to suggest some design / talk
about it without
knowing the various protocols well, i do know RTP/RTSP a little i dont
know the MS/REAL variants at all

The whole highlevel structure is undocumented
i mean like
a diagram of what parts are part of initialization, and demuxing
like which function calls what and how packets are passed around
a little like demuxer->parser->decoder
but with much more details

If a bugfix only changes things apparently unrelated to the bug with no
further explanation, that is a good sign that the bugfix is wrong.
