[vlc] RTSP: How to Announce EOF event to the RTSP Client

[ravinder]

What you are saying is that RTCP should be sent with RTP/UDP as well as
MP2TS/UDP and vlc does that right? But, rtsp client is not sending TEARDOWN
in the case which I have explained in trailing mail, rather it is waiting
for MP2TS data. It will be helpful for me if you could clarify my other
doubts as well.

RTCP is not an optional part of RTP. Not even for MPEG2-TS. Some people
think 
that RTCP only does lip-synch, which is indeed not needed for TS. If you
don't 
send RTCP then de-jitter does not work, neither EOF detection, nor minor 
things like packet loss statistics.

No. The server needs to send RTCP compounds.
