[Live-devel] void RTPInterface::sendPacket

[Ross Finlayson]

>why it have to send a UDP packet and over TCP socket?

For most streams, RTP and RTCP packets are sent via UDP only. 
However, for some RTSP streams, RTP and RTCP are sent via TCP instead 
- if the RTSP client has requested this.

In one special case - a RTSP server that streams to multiple clients 
from the same input source ("reuseFirstSource==True") - it is 
possible for a single "RTPInterface" to stream via both UDP and TCP 
(to different clients).
