Unfortunately just crowd video, (not that the crowd video isn’t inspiring) at fox live feed.

Has audio and crowd pictures
http://www.cnn.com/video/flashLive/live.html?stream=stream2
has video and audio of speakers(live feed starts after a 15 second commercial)
The CNN link has by far the best coverage.
I’ve switched over to CNN live stream: http://www.cnn.com/video/flashLive/live.html?stream=stream2
(Damn Fox. They always blow it on the live stuff!)
