Web : Record webcam and send it to a remote server

I need to allow my website users to record short clip (audio and video, less than 1 min) from their webcam and send it directly on my remote hosted server. I read a lot about webRtc, html5 implementation etc, but i need a solution working on all recents browsers (IE and safari included...) and on all plateform (windows, OSX ). Do i necessary need to develop 2 solutions, one with html5 support, and if not available, a fallback with a flash plugin or there is an existing solution (free would be great) which already handle it for us ? I've read about addpipe, which sounds good but they stopped their videos records support.
