Solution 1

yes but i won't give a code example without you trying.

what you need to learn and implement:
1. learn to make and use UDP sockets
2. rtp is an application level wrapper than comes after UDP data layer, you'll need to interpret the initial binary bytes of the UDP payload to interpret rtp

We help, not bail out... :) ... Anyway, the current RTP standard is version 2 (http://tools.ietf.org/html/rfc3550), I would start out by reading a generic definition (http://en.wikipedia.org/wiki/Real-time_Transport_Protocol). You'll find the generic definition tells you just about everything you need to implement RTP, any clarification can be found in the standard. I implemented my RTP handler in one day.

Thanks Albert, Will go have a look at all this right now..

..and I'm not sure CIP itself (a video header) is transmitted when using RTP, since they contain mostly redundant data, you'll have to figure that out...
