I impliemented a LIVE555 RTSP server, and connected it by VLC as a client.
Our RTSP server will keep streaming to a client (and keep its RTSP
connection open) as long as it keeps receiving an indication that the
client is 'alive'. A client is considered to be 'alive' if the
server receives a RTCP packet from the client, and/or receives any
RTSP command (including "GET_PARAMETER").
VLC - as a RTSP/RTP client - does both of these: it frequently sends
RTCP RR (Reception Report) packets (because RTCP is a manditory part
of the RTP/RTCP protocol), and it also periodically sends
"GET_PARAMETER" commands.
Therefore, if a VLC client communicates with a LIVE555 RTSP server,
the connection should not end prematurely. (If it does, then the
cause must be something unrelated to VLC or LIVE555 - perhaps a
network or firewall problem.)
