This was the second switch in rtp_parse packet.
Normalizes time, if required, sets stream_index, etc.

open a new RTP parse context for stream 'st'.
'st' can be NULL for MPEG2TS streams to indicate that they should be demuxed inside the rtp demux (otherwise CODEC_ID_MPEG2TS packets are returned) TODO: change this to not take rtp_payload data, and use the new dynamic payload system.

| void rtp_send_punch_packets | ( | URLContext * | rtp_handle | ) |
Send a dummy packet on both port pairs to set up the connection state in potential NAT routers, so that we're able to receive packets.
Note, this only works if the NAT router doesn't remap ports. This isn't a standardized procedure, but it works in many cases in practice.
The same routine is used with RDT too, even if RDT doesn't use normal RTP packets otherwise.

returns 1 if we should handle this packet.
