On2 Flix Live makes broadcast–quality video webcasting on the Flash Platform available to enterprises and content delivery networks. It is the first application on the market that is capable of encoding live feeds in On2 VP6, the advanced video technology in Macromedia Flash Player 8 from Adobe. The application is powered by the On2 Live SDK for Flash, which delivers live Flash video at the highest image quality while also maintaining low streaming latency. Working closely with Adobe, On2 designed the On2 Live SDK for Flash to deliver live streaming video directly to Adobe’s Flash Media Server 2.0 using Adobe’s RTMP (Real Time Messaging Protocol).

Nice to know, although I’m not sure what using it entails. Encoding is usually done client–side in the player, but the blurb states that it

Includes pre–build Flash players

so I’m wondering if you get a custom build of the player that is capable of encoding to VP6, before sending the stream back to FMS2?
