2019 Macbook Pro cannot play Youtube Peru 8k?

[avxkim]

No problem on my own build Ryzen 1600 with nvidia 1070 windows 10. I guess apple graphic drivers aren't the best.

GPU has zero % utilization when viewing this 8k video, only CPU has like 40-50% as activity monitor says.

I have a 2018 13-inch MacBook Pro with the Intel Iris Plus 655 GPU and it plays smoothly with no stutter at all. Even got an external 1080p Dell monitor connected with the internal display as well. On an 100Mbps connection.

If my 2018 Intel GPU can play it, surely the 2019 can.

This is using Google Chrome at 4320p (8K).

That's not true at all, at least on windows 10. Firefox as well as Chrome take full advantage of GPU acceleration for video playback. Please Check screenshot attached.
If I drop video quality to 4k GPU utilization drops to 30-40% meanwhile CPU its only 5%.

Hello guys ..this is Cyrus and this would be my first post.

I use my Late 2013 MBP maxed out as my primary computer.
I have come across this video since I had the kernel_task high CPU usage issue.

I see also of ppl have the same issue ..claiming they have issues running this on their latest andgretest hardware.

I can confirm , this video ran smoothly since mnts now on my machine until 10.15.4.

The difference i notice..if i play the video for 10 - 15 mins...Kernel_task would hit the roof ..
but after the update ..the video dsnt play more than 3 mins and stutters and the "chome helper" reached 1000%++CPU usage.

any thoughts ?

Same for me... Windows 10, Chrome, i7-4790k, 32GB RAM, RTX 2070

CPU utilization is minimal... but GPU utilization is directly related to Youtube playback resolution:

78% - 8K
69% - 4K
36% - 1440p
21% - 1080p

Probably because Macs are trying to do it without using hardware acceleration as per my comments in the MacBook Air 2020 thread(s)

Google stopped using h.264/h.265 and now use VP9 for anything above 1080p, which Apple refuse to support in hardware acceleration. The hardware does it, macOS does not. Complain to Apple that they need to get with the program and support VP9 hardware acceleration.

Isn't google just as much to blame since they didn't want to pay the royalties?

No not really, because VP9 is free for everyone. Which means browsers like Firefox can freely support it, Linux can freely include it, etc.

There is zero reason Apple aren't supporting it (as well as h.265) other than to be pig headed because they're part of the h.265 committee. There's zero reason they can't support both, and the CPUs in their computers since 2016 have hardware acceleration support for both. Apple just do not expose the VP9 acceleration in macOS. If you run windows on the same machine, you'll get it.

The losers here are the Apple end users. Everyone else on non-apple machines can play YouTube accelerated if they have the hardware for it.

And we're not talking a small processor/battery usage saving here either. The difference is an order of magnitude or more (i.e., 10x or more) less processing power required if the hardware acceleration instructions, inbuilt into every intel CPU since 2016, are used.

Every other OS vendor supports either both (except for totally open source/free Linux or other free projects that can't due to the royalty fees required in h.265) - or VP9.

so should i be worried that my 2019 16 2.4/64/5500M stops every few seconds?

edit - with switching turned off and CPU is at around 70% usage... is that normal?

No. If only it was as simple as Google refusing to pay h.264/h.265 royalty. Youtube still provides 1080P videos to Safari via h.264, so we know they are still paying royalty on that.

But VP9 vs h.265 is not a close race at all. VP9 is just more efficient than h.265, both to decode and to encode, both in software and on the hardware.

Google will have to pay for royalty, waste more storage space, waste more bandwidth, bloat Chrome up even more (as if it's not already bloated) and only so that Mac users will be able to enjoy contents above 1080P, of which there are not a lot?

It doesn't sound like a reasonable proposition.

Also, to add insult to injury, VP9 hardware acceleration on AMD graphics is borked because AMD is again being very lazy with their drivers. As a result, the 16" MBP doesn't have hardware acceleration for 8K VP9 even in Bootcamp.

Not that I'm complaining, since there are not a lot of 8K contents either, but it's something to note.

Yes, you should be afraid. You should be very afraid. Sparta will burn to the ground!

...or just don't watch 8K videos. I think they are nice as benchmarks now, but there is barely anything recorded in 8K anyways. Now... if it's 4K, and you can't view it, then yeah, please do complain.

seems like people with older models play this fine...?

seems like people with older models play this fine...?

Which people? I'm seeing people claim false things in this thread that I could challenge but I'd ignore. For instance, someone said the video played fine on his 2018 MBP 13". That's false... unless they're running Bootcamp. MacOS simply allows no access to hardware accelerated VP9, so there is absolutely no way for VP9 to be ran on the GPU in Mac OS. It's an issue at the OS level, not something you can solve without Apple intervening.

But... even if you have Bootcamp, most AMD graphics DO NOT have VP9 hardware acceleration for anything beyond 4K60. Unless you happen to run either the 5700 or 5700 XT in eGPU enclosure. So tl;dr: your 15" MacBook since 2015 has not been able to get 8K hardware accelerated VP9 decode at all, no matter if it's on Bootcamp or Mac OS.

Everybody who has said that they have this 8K video running "smoothly" probably does not realize that they are forcing the video on to their CPU, regardless of whether it's in Bootcamp or in Mac OS.

This is where we can blame Apple for another thing: they keep insisting on AMD graphics even though drivers are horribad. I can't even seem to get DisplayPort 1.4 working properly on my 16" MacBook Pro and I have to resort to "downgrading" to DisplayPort 1.2 for it to work properly with my monitor. This happens both in Mac OS and Bootcamp so it's partially not Apple's fault (it's AMD's fault for providing such shoddy drivers), but... if Apple had gone with nVidia graphics instead, none of this would have happened. Apple's feud with other companies is slowly causing their computers to fall behind.

Note: you'll still be able to do 8K videos just fine, even with VP9, just that VP9 will force your CPU to work overtime.

P.S.: sorry, but I think people miss facts too much in this thread and they are worrying too much. I'll say this again: don't worry about 8K, especially not at 60fps. Unless you're a cinematographer, then in which case, you know to record your videos in h.265 (HEVC) format and enjoy full hardware acceleration on your Mac.

A 13" macbook pro running it completely smoothly at 8K60fps resolution/frame rate on its relatively weak CPU only, without access to hardware VP9 decoding in macOS sounds like complete bollocks. Especially that report of a pretty old 2013 model previously running it fine at 8K before an update.

Is everyone completely sure that they are selecting 8K60fps and playing it while monitoring the 'dropped frames' statistic in the 'stats for nerds' accessed by right clicking the video.

Or has Apple finally allowed access to hardware accelerated VP9 decoding in a very recent update?

 

[Hieveryone]

Works great on my 2019 15" base model



Kidding, it stutters just like everyone else's

But I don't really care. I don't watch these 4k/8k/250k videos. They're nice though.
