Safari And YouTube 4K video

[snow755]

Hi

any one running Safari. On a 4K iMac are you able to watch 4K videos in safari ? On Mac OS Big Sur ?

 

[Kylo83]

no

 

[head_bigg]

Have Apple still not added this in?

 

[darthaddie]

No they don't play in 4k. Its more to do with the VP9 codec and licensing than Apple wanting to support it. I don't think its gonna come soon enough.

 

[jaack]

No but it's working on Apple TV & iOS (Youtube App) so I expect Safari might follow soon?

It only goes up to 1080p for me on the iOS app on iPhone & iPad Pro

 

[RedlegsFan]

Well, I guess its still Firefox for me, at least on my iMac... ugh...

 

[ScreenSavers]

Still Chrome for me...

4k, 8k video playback and extension support are 2 reasons why chrome is still my go-to browser. 8k youtube videos play buttery smooth on my 7-year-old pc running i7-4770k and rtx 2080 ti w/ my symmetrical 1.5gbps internet. I rarely use google search anymore. Duckduckgo ftw. I think safari is getting there but not quite there yet for me to replace chrome.

I think they might start supporting 4K using AV1 codec instead of VP9 (like on tvOS?). But could not find any AV1 video that would play as 4K in Safari on Big Sur. Let me know if you find some. I’m working on an extension that detects 4K in Safari (“4Ktube”). Once Safari can play some 4K videos, I plan to update the extension to warn only about unsupported VP9 videos.

may be they can add that stuff in later updates

There is a play list of AV1 videos https://www.youtube.com/playlist?list=PLyqf6gJt7KuHBmeVzZteZUlNUQAVLwrZS

Also did you go to www.youtube.com/testtube to switch to AV1?

If they can support it on iOS/ tvOS, then they can support it in Safari. I really hope they do because lack of 4K YouTube is a major drag. For my use, there would be no need to have a separate browser.

No luck here. Also this shows no AV1 support:

HTML5 audio/video tester - File type player - MIME type tester

A free online HTML5 audio and video tester to test file type and MIME type

tools.woolyss.com

And I could not find any mentions of av01 in the system files.

This is Safari or YouTube app?

Doesn't work in Safari... Only in Chrome. YouTube only encodes 4K videos with the VP9 codec but Safari/Apple Doesn't support VP9 as a codec, even if the hardware is capable.

I believe YouTube are now starting to encode 4K videos in AV1, which is an open source codec. This codec is supported by Apple. Who knows if/when YouTube will re-encode VP9 videos into AV1 videos.

 

[Ritsuka]

There isn't a VP9 or AV1 decoder on macOS yet in the first beta. So no changes at the moment.

Yep YouTube app

Are you running iOS 14 beta? The best I can get is 1080P HDR in the YouTube app on iOS 13.5.1.

Yeah I'm running the iOS 14 beta

 

[ek9max]

I can't seem to get 4k on my iphone 11 pro max on Ios 14 beta either. Tried on youtube app and safari.

Oh I went to the same. video and it worked. I bet that video is working in AV1 and not VP9.

 

[cezar.cretzu]

i think it has to do with HDR videos only. was reading this somewhere and indeed all 4k hdr videos play 4k in youtube app on ios 14
