>Youtube happily provides 4k video in H.* formats elsewhere. Do they? Because if I put a 4K video through youtube-dl -F, I get this: 248 webm 1920x1080 1080p 1392k , webm_dash container, vp9@1392k, 24fps, video only, 193.77MiB 137 mp4 1920x1080 1080p 2650k , mp4_dash container, avc1.640028@2650k, 24fps, video only, 368.92MiB 271 webm 2560x1440 1440p 3453k , webm_dash container, vp9@3453k, 24fps, video only, 480.62MiB 313 webm 3840x2160 2160p 10434k , webm_dash container, vp9@10434k, 24fps, video only, 1.42GiB

Youtube will happily stream this in H.264 if WebM isn't available. https://support.google.com/youtube/answer/2853702?hl=en https://support.google.com/youtube/answer/2853702?hl=en > HTML5 streaming: Many browsers support HTML5 and either the H.264 video codec or WebM format. As others pointed out, this could be about AV1. Which still is bull crap because YouTube hapily delivers video in H.* or VP9 when needed. And it looks like the only reason Google stopped encoding in H.* to everyone's hand whether it's good or bad. This definitely has nothing to do with "opensource codecs".

  YouTube doesn't create H.264 versions for 1440p or higher. If there's no VP9 support, the best resolution you'll get is 1080p. Some Apple devices are (or used to be?) affected by this. For example, on Mac, Firefox or Chrome have been able to play 8K YouTube videos for a long time while Safari couldn't go past 1080p. This was "fixed" a few months ago, but only because Apple added VP9 support. I don't think H.264 will disappear from YouTube anytime soon. They'll continue to use it as a fallback for devices that can't play VP9 or AV1 files. In fact, I wouldn't be surprised if VP9 was dropped before H.264 when AV1 support (and YouTube's encoding capabilities) improve. At the end of the day, Google/YouTube doesn't have to use a paid and proprietary codec like H.265 and Roku doesn't have to support VP9 or AV1 with hardware (or software) decoding. But since H.264 support is still there, the hardware should be able to play 1080p YouTube videos without a problem.
