I wonder how this stacks up quality wise to x264. I thought it was a bit suspect that a few months back Cisco announced they would release this under a permissive open source licence only after H.264 was accepted as Mandatory To Implement in WebRTC, while also continuing to argue for H.264 vs VP8 using the highly regarded (though GPL/dual-licenced) x264 encoder.
Also, how can this possibly be legit according to the patent license? Or do the patent owners turn a blind eye, like Microsoft in China, and Adobe with student piracy with their eyes on not losing control?
