Derek Buitenhuis is the senior principal video engineer at Vimeo, although he's been deeply involved with ffmpeg and VideoLAN (among other open source projects). Derek talks about how the only stakeholders really interested in next-generation video codecs like AV1 or VVC (and even last-gen like VP8/VP9 and HEVC) are megacorporations or people actually involved in developing the standards themselves. Derek's argument is that the bandwidth savings you get with extra efficiency aren't that great compared with the other costs you have to pay; H.264 is good enough for most people and businesses today.
