I might be missing something, but I don't see any particular RDT
handling code in rtsp_fetch_packet other than rdt_parse_packet. Do I
still need to do something?
Attached patches address all comments so far:
-Add in rtp_get_rtcp_file_handle function, preserving the deprecation
of rtp_get_file_handles
-Counter for the number of BYEs received, which is reset after a seek.
If nb_byes == nb_streams, we return EOF. As mentioned earlier, this is
probably not the correct behavior.
Autoexit does not trip under my tests, perhaps because with this
patch, the EOF never makes it back to ffplay. Instead,
av_read_frame_internal tries to return some (bogus?) final packets
(utils.c:1119).
