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. Cheers, Markus Markus Buchhorn, ANU Internet Futures Group, |Ph: +61 2 61258810 markus.buchh...@anu.edu.au, mail: Bldg #108 CS&IT |Fx: +61 2 61259805 Australian National University, Canberra 0200 Aust.|Mob: 0417 281429
