It looks like all participants video stream might be send in a single RTP-stream. My guess is that it shouldn't be that hard to dissect this stream and show. [1] The hardest thing might be to track who is speaking. There is a bit called "the marker bit" as part of RTP protocol that signals the start of voice in a stream after a time of silence that might be useful.See second answer on Stack Overflow [2]
