Hello, I am trying to create a simple RTSP Proxy which makes use of
PassiveServerMediaSubsession instead of OnDemandServerMediaSubsession.
What I am doing is just a test just to see if the result is acceptable
for our application ad is as follows:
The source of my video is an Axis Q7424-R server.
I create a RTSPClient and do all the RTSP requests (Describe, Setup and
Play) on one Media Session which contains only a Media Subsession with
the video stream.
Once the Client is beginning receiving the frames I setup a RTSP Server
and do following:
- create two Groupsock (one for RTP and one for RTCP)
- create a RTPSink of the appropriate type (in my case H264VideoRTPSink)
- create RTCPInstance
- create PassiveServerMediaSubsession
- add Subsession to the ServerMediaSession and add the
ServerMediaSession to the RTSPServer
- start the sink providing the source of the Client Media Session
Once I connect a client to my proxy everything works correctly except
that I receive the video with has a significant delay (1 or 2 seconds).
I noticed this opening with the same player (Axis Media Control) both
streams: the original and the proxied one.
If I proxy the same stream using the live555ProxyServer I do not have
the same delay, so probably I am doing something wrong, but what??
Thanks for helping...
Bill
