Given that HEVC (H.265) support looks even worse (https://caniuse.com/hevc https://caniuse.com/hevc), it seems like realistic options are a) AV1 with H.264 fallback b) AV1 with H.265 for Apple and H.264 fallback. On one hand I'm glad that patent-infested HEVC won't take off, on the other hand, I believe my phone outputs videos in HEVC or H.264 only :(

  > AOM is being sued by the EU for not offering FRAND terms Can you expand on this? If I'm reading correctly, the issue is 'mandatory royalty-free cross licensing' which is supposed to bring down innovation? If yes, this sounds like some grade A bullshit.

  Anyone can set up a patent pool claiming to be for anything, and hope fools will buy it. This scam has been done to previous VPx codecs too. And anyone can sue anybody for anything. Until there's a judgement it doesn't mean much. But there is an alliance around AV1 patents, and it has strong backers to fight off the trolls: https://aomedia.org/membership/members/ https://aomedia.org/membership/members/

H.265 was held back by the insane licensing costs, hence why everyone uses H.264. Sad cost the file sizes of H.265 are legit as. I wonder why ffmepg can encode as H.265 if there's licensing fees?

  ffmpeg project doesn't ship binary; patents do not apply for study and research. Now shipping ffmpeg binary in some jurisdiction would need licensing. If you compile and use it yourself, the licensing in these jurisdictions is on you. Another factor for AVC against HEVC is, that at some resolution and bitrates, AVC still provides better results.

    Particularly when going for transparency to source material and when using the bloody fantastic piece of kit that is x264, agreed

What license is AV1 available under? Is it really "open" like they say?
