It depends a bit on what you want to do with the video streams afterwards, but basically
- you can capture rtp packets and work with the content at that level (see e.g. rcbridge and rtpreplicate)
- you can capture the rtp packets and unpack them to access the video data itself (see e.g. VP)
(http://if.anu.edu.au/AG.html has links to the above packages, with source code)
So in the first instance, any standalone application that can listen to a multicast socket and accept udp/rtp(+rtcp) packets would be a starting point.
The next interesting part, if relevant, is integrating it with the AG venue client or as appropriate to 'do something' from the AG user-interface. That really depends on what the application does, if it's a node service or a venue service, etc.
