Safari Users Unable to Play Newer 4K Video On YouTube in Native Resolution (macrumors.com)

It appears Google recently turned on VP9 codec on YouTube for delivering 4K video. However, because of this, Safari users are unable to watch videos uploaded to the service since early December in full 4K resolution. From a report: Specifically, YouTube appears to be storing video on its servers using either the more efficient VP9 codec or the older H.264 codec. Safari only supports the latter, which explains why recently uploaded 4K videos are only able to be viewed in up to 1440p. Funnily enough, the same videos can be streamed by Safari in native 4K as long as they're embedded in another website, suggesting that the VP9 codec support requirement only applies to videos viewed directly on YouTube's website. Until Apple updates Safari to support the VP9 codec, Mac users who want to access newer 4K video on YouTube in native 2160p resolution are advised to use a different browser.John Gruber of DaringFireball writes, "I'm curious what Google's thinking is here. My guess: a subtle nudge to get more Mac users to switch from Safari to Chrome. 4K playback is going to require H.264 support if they want it to work on iOS, though."

Do any iOS devices even have native (hardware decoding) support of h.265 let alone VP9?

Re:iOS

The iPhone 6 (A8 processor) and newer can natively encode/decode H.265 in hardware. However there is no API for 3rd parties to access it currently for some reason. The only place in practice it gets used is in FaceTime calls between users with the capable hardware.

Edge supports VP9

Windows 10 "Anniversary Update" includes Edge 14, which supports VP9. That leaves Apple as the holdout supporting only codecs that require payment of a royalty to a patent pool.

Who needs 4k video?

4k is good for video editing, it is good if you watch blockbuster movies on a bigass screen, but for YouTube videos on your computer, really? It is a tech demo, there is little use for it.
To enjoy 4k, you need a monitor that supports it, that is large enough relative to the viewing distance, enough bandwidth and processing power. You also need a 4k source. Few people produce 4k video : it is more expensive, more difficult and the result is only marginally better.
If you manage to check all the boxes, then the browser is the least of your worries.

One day, maybe 4k will actually bring something, but it is a bit too soon. Still, it's interesting how far ahead Apple is when it comes to removing stuff (floppy drive, ethernet port, headphone jack, ...) but not so much when it comes to actually support the technology of the future.

I think you'll find these boxes are checked more and more.

On the consuming side, 4K monitors are coming down in price very quickly and are at the point where it's reasonable for the layperson to get one. 4K makes a notable difference on a 24" monitor at the common 2-3' distance -- anyone who says otherwise has bad eyesight or hasn't used one yet. Bandwidth-wise 4K uses about 20-30mbit, which is a lot of users these days. With H.265 they should be able to drop that number considerably for most videos.

On the production side, 4K video is already becoming increasingly more common on YouTube as the latest inexpensive professional and amateur cameras -- even phones and gopros -- all support 4K. Editing really isn't much different versus 1080p -- it's not like they're using rendering farms to create special effects.
