AV1 doesn't require any proprietary hardware, and it's free for hardware vendors to implement too.
This is unlike H.265, which requires patent license fees for every chip made.
- kmeisthax 4y agoCorrection: H.264 requires patent license fees. H.265 requires three patent license fees, since two other competing patent pools promised a handful of patent owners a deal on cross-licensing if they left MPEG-LA. AV1 may not require a patent license, because Google designs the codec to only use unpatented or royalty-free patented inventions. However, there's still considerations of submarine patents - i.e. an unrelated entity that invented the same technology before Google. Parallel reinvention is not a defense against patent infringement - there is no inverse to prior art. This is the same reason why Microsoft refused to support VP8/WebM early on in IE - patent pools were supposed to provide an incentive against that sort of trickery. Then Velos Media and Access Advance came along and broke this, which is why the naysayers started piling on into AOM.
