Re: [Live-devel] Calculating rtptime for RTSP/PLAY-Response "RTP-Info" header

2008-08-07 Thread Chris Burns
The crux of my question concerns the *delta* that a reference implementation (Helix USM) applies to one of the rtptime=X values that is reported in the RTP-Info header. All of our testing (with ~30 different brand/model combinations) has shown that this is critical for many mobile phones to correct

2008-08-07 Thread Ross Finlayson
I'm specifically trying to work out how to create the "RTP-Info" header in a RTSP/PLAY-Response. Our server implementation does this automatically (see "RTSPServer.cpp", and search for "rtpInfo"). You shouldn't have to do anything yourself to generate this. Similarly, at the client end, the

Sorry, I should have been more clear in my question... I'm specifically trying to work out how to create the "RTP-Info" header in a RTSP/PLAY-Response. It looks quite simple. Grab the RTP-Time & SeqNum of the first RTP packet sent on each stream to the client, format it correctly and we're done

Hi Melvin You could... add the command line parameter as the parameter for debugging in VS2005, then start RTSP.exe from within VisualStudio and step through the code (I think F10 is the default for step, and F11 for step into), set a lot of breakpoints, dig in and prepare to learn a lot from s

Hello Mike In my particular case, I was looking for lost packets (RTSP over UDP) in order to figure out how I should deal with those in the codec and also what the RTCP packets were containing, since I couldn't figure out the weird data I was getting. The graphs don't tell me much either. N
