how is the presentationtime of two streams synchronised?
Please read the FAQ!
I have to synchronise the mpeg-4 es and a wave file. I am able to send the two streams together by creating single servermediasession and adding two separate servermediasubsession, but they are not synchronised. In case of mpeg-4 es video, the gettimeofday() is getting called when the constructor of MPEGVideoStreamFramer is called and in case of wave, in WAVAudioFileSource::doGetNextFrame(). I think due to this the video and audio is not getting synchronised. So in this case how should i synchronise the audio and video?
You *must* set accurate "fPresentationTime" values for each frame of each of your sources. These values - and only these values - are what are used for synchronization. If the "fPresentationTime" values are not accurate - and synchronized - at the server, then they cannot possibly become synchronized at a client.
