Google has a plugin for voice and video chat that can be used from within GMail. This is like Google talk, but it runs from within the GMail window instead of as a separate application. It is available here. The plugin is available for both Mac and PC. The problem: Yesterday I tried using this to chat with a friend who has a PC. Voice worked fine, but I couldn't figure out a way to activate the video (my Macbook has a built in iSight). Has anybody gotten video to work using the GMail videochat plugin? Thanks in advance.
