And engender endless further discussions about what is "100% royalty free". I'll note that even MPEG-LA deciding to RF baseline H.264 doesn't mean it's 100% royalty-free (witness Nokia's lawsuits). You can never say "100%" with royalties/patents unless something is so old every possible patent has expired - and you're still not really safe on your encoder even then, unless you use an old, published encoder largely unchanged.

Nothing stops those that want to from implementing both, without or without the mandate. I don’t think this would make any material difference to what happens, but it makes the spec and reality a little closer. > > > > Finally, I wonder, what would it be like if we actually tried to get closer to interop: ALL endpoints — anything that can operate at one end of a WebRTC session, be it device, UA, gateway, compatible-endpoint, whatever — must be able to decode (actually, offer to receive) both, and must be able to encode at least one? I’d have to think about the consequences of doing decode-only, but it’s a loss less work than a decent encoder, for a start. This would result in interop if people actually did it. That option was floated when we did the survey. I rated it above many others myself (though not as good as vp8-only). IIRC it didn't do well; too many people in the A and not B or B and not A camps. -- Randell Jesup -- rjesup a t mozilla d o t com
