Does RTP Packets using RTSP protocol contain both audio and video

Question

I am developing a client program which will display the media captured from IP camera. So I want to whether the RTP packets using RTSP protocol contain both audio and video if contains both how should I extract it?

Answer 1

RTSP stream does not carry video/audio itself, it provides a method to control independent RTP video and audio streams (they are in turn independent one from another).

One of the options though is when RTP streams are tunnelled through RTSP connection, in which case all communication might be taking place through single TCP connection.

Answer 2

You can read the SDP returned in the SETUP request to the RtspServer.

There should be a MediaInformation for each stream available.

That will tell you if there is audio or video etc...
