Applications using ANY rtp specific function from rtp.h are broken, this stuff
is not public API, whoever added it should be shot!
rtp.h should be removed! It cannot even break ABI, and anyone who uses it,
well they have to fix their code anyway. Bumping the major version wont make
it any easier for them, use of the code in rtp.h was always wrong.
If one wants to get a list of file handles, there should be a
not a rtp_get_file_handles() which will crash with non rtp
libavformat is not a collection of incompatible random APIs from different
(de)muxers and protocols but a common generic one. Which allows users to
switch between 2 protocols by replacing just the url used. rtp_* breaks this

your change of AVRtpPayloadTypes -> static broke the ABI if one assumes
everything in rtp.h to be part of the public API/ABI
removing rtp.h from the installed headers cannot break the ABI
but as said rtp.h should never have been installed, i do not know why it
was added to the installed headers ...

Many that live deserve death. And some that die deserve life. Can you give
it to them? Then do not be too eager to deal out death in judgement. For
even the very wise cannot see all ends. -- Gandalf
