The properties that you're asking about - video width & height, video frame rate, audio sampling frequency, audio number of channels are almost always contained within the media data themselves, and are therefore accessed by your decoding software (or hardware), when it parses this media data.

Hi all, I am implementing an RTSP Client using the livemedia and much of work has been done successfully using the lib. Many thanks to developpers. What I need is to discover the properties of any stream, i.e. video width and height for audio and frequency/channels for audio in different formats

Hi, I'd like to write a simple RTP/RTCP server and client using the live555 libraries. I've previously managed to do the same with jrtplib, but it looks like the live555 libraries are more comprehensive since they offer RTSP and other functionality too. At the same time I'm not quite sure where
