some rtp servers assume client is dead if they don't hear from them...
so we send a Receiver Report to the provided URLContext or AVIOContext (we don't have access to the rtcp handle from here)
void ff_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.

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