I have a similar question - although I haven't poked around in the code yet.
I've got a Shared WhiteBoard app in the works. Fairly simple - essentially just a wrapper around wbd - which runs on Windows and Linux (although I haven't worked on the Linux startup part yet). Right now it just hardwires a multicast address and port to do the communication. What I'm thinking of doing is extracting the multicast address and port of the video stream and allocating a port that isn't being used on that address. Then keeping track of that somehow, so that a second white board in the same venue would get a still different port. So, first question - is there anything basically wrong with this approach? And second - are the hooks available and documented (pointers to code is fine) that will give me the current multicast address and port of the streams in a venue? Thanks!! -randy At 04:23 AM 10/8/2004, Socrates Varakliotis wrote: >Hi: > >I was looking into AccessGrid/Venue.py, around line 926.
