Hi, I have AG 3.1 almost working on my lenovo T500 with in-built webcam (running FC10), but I'm stuck on the video out.
I have video/audio working perfectly in other applications e.g. skype. I followed the single-node setup instructions for FC10 provided on www.accessgrid.org. The network I'm on isn't multicast so I go through a unicast bridge. Audio in/out both work. Video in works, but video out has never worked. In order to get video out working, I got access to an IP address with "weaker" firewall (I read that firewalls can prevent audio/video working properly) and that changed things somewhat, but video out still doesn't work. Previously (before changed firewall) I would get the window with the video streams (where you can mute/unmute) and my video stream wouldn't be listed even though the light on the (in-built) webcam was red and was supposedly transmitting. Now (with changed firewall) the webcam light goes on for a second and then goes out, and the window with the video streams closes (it happens so quickly, it doesn't get populated with streams). I've run Venue Client in debug mode, and this appears to be where things are dying: V4L2: start V4L2: format cifdecimate: 2 V4L2: setting input port to 0 V4L2: failed to set format! requested 352x288, got 320x240 V4L2: trying resolution under ...

If the answer is: inbuilt webcams and AG don't play well (you've got buckleys) then I would appreciate if someone could recommend a good (and reasonably priced) external webcam that will work well with a linux machine running AG.
