Anyone involved in the audio/video codec debate cannot say we do not see this coming: A slight relaxation of H.264 codec royalties by the patent pool holders as reported by TheRegister.
Obviously this is an reaction to WebM, the format Google is pushing and which comes with a license condition that is way much lenient than H.264, even after considering this latest concession.
Is it good enough to start adopting H.264. No. The concession is there to encourage adoption on the web at the expense of the other, extremely important activity around H.264, the creation of H.264 contents. That is still not free.
WebM is still important for the future of videos and audios on the web in particular, the general audio/video landscape in general.
TheRegister always like to point out that Steve Jobs jibes with the patent pool when it comes to free format such as Ogg/Theora and WebM. May be we will be seeing a battle in the future. But I am willing to bet you that if WebM gains traction, Jobs will put it into Safari, regardless of his reservation about WebM.
