I read that openRTSP can send GET_PARAMETER as keepAlive (or client
liveness indicator) but nothing in the source code show that (in
RTSPClient.cpp).
Not true. The "RTSPClient" class supports sending the
"GET_PARAMETER" command, using the "getMediaSessionParameter()"
member function. (However, our "openRTSP" demo application does not
use this.)
During our session, the timeout is sent by the video server in the
RTSP SETUP response and catched by openRTSP, but nothing append then
when the time expired.
Why no behavior has been developped ?
Is there any player that can be able to send GET_PARAMETER in place
of RTCP "RR" packet ?
I believe that the "VLC" media player will send a periodic
"GET_PARAMETER" RTSP command (*as well as* sending RTCP "RR" packets,
which is the proper, standard way in which a client indicates
liveness) if the server responds with a "timeout=" parameter.
