Is the Adobe Flash plugin the only way two people can video-chat, using a web browser?

if two people want to video chat using a web browser and their camera's, is Adobe Flash the only plugin available? Yes, there are other 3rd party plugins, but those all have to be manually downloaded. So only using what is baked into the common browsers, is Flash the only way this is possible?

Also - HTML5 browsers** are acceptable .. so that开发者_开发技巧 might help someone answer this question. I understand there's so many browsers and browser versions, so lets just say the latest versions at the time of this post - no IE6, etc.

** Not sure if HTML5 spec for video is just for playback or both playback and interaction with camera's.

you can use the WebSocket technology to stream data to the browser. so this part of video chat would be covered.

the camera interaction is not implemented yet: you can check it here: http://caniuse.com/#search=camera
