YouTube HDR... finally

[Kuschelmonschter]

YouTube HDR content is finally available!

You will find a playlist here. However, these clips will be played as SDR on Sonys for now.

With youtube-dl you can find vp9.2 encodings for those clips:

330          webm       256x144    144p60  156k , vp9.2, 60fps, video only, 2.38MiB
331          webm       426x240    240p60  256k , vp9.2, 60fps, video only, 3.87MiB
332          webm       640x360    360p60  485k , vp9.2, 60fps, video only, 7.35MiB

334          webm       1280x720   720p60 1991k , vp9.2, 60fps, video only, 28.18MiB
335          webm       1920x1080  1080p60 3201k , vp9.2, 60fps, video only, 49.70MiB
336          webm       2560x1440  1440p60 11166k , vp9.2, 60fps, video only, 170.23MiB
337          webm       3840x2160  2160p60 20122k , vp9.2, 60fps, video only, 335.45MiB

Those are webm however which the native Video app won't play.

We will see whether we will get support for it soon, even for the early 2016 models with the old MediaTek SoC from last year. At least Sony promised that back at CES:

Spoiler

YouTube will also start streaming in HDR quality later this year, using a new VP9-Profile 2 codec that brings HDR support to Google’s VP9 video format. Sony’s Motoi Kawamura, Head of TV Product Planning for Sony Europe, confirmed to FlatpanelsHD that the 2016 models will support VP9-Profile 2 and be capable of streaming YouTube in HDR. We saw a demo at CES and it looked very good.

I mean settings inside video to choose video quality.

Logitech touchpad does not respond on any click. Just pointer moving, Enter and Escape key

[Kuschelmonschter]

Video quality cannot be manually selected with 2.0 anymore.

I am just watching SONY 4K hdr demo video for 4k tv-2160p.(Video ID: Bey4XXJAqS8)

What I see is an HD symbol on the top right. This means no 2160p.

And there is no option to change on More options

They are improved

Funny. It's like if for once Google heard my wishes.. Today many videos are playing at 2160p@30fps. Videos that usually played at 1440p@60fps included. Apart from the usual  "The World in HDR". That's still 1440p@60fps.

Anyway, also the logo 4K finally shows in many videos. But they may take a bit to reach 2160p from 1440p.

'Optimal Resolution' in nerd stats tells you what you can reach. That's always the maximum on the given device for the given video...

Yeah, but I am talking also about the real Resolution (as usual the video doesn't show inthe screenshot..):

Which after rebooting the TV is up to 3840 x 2160@60 in The World in HDR:

Please note how it also says 4K in both videos. They are back to 4K. I mean, even better than before, because I don't remember getting 2160p@60fps ever. Now it finally does it.

BTW so much for our friend saying "its a web view! It's unefficient because of Cobalt! Blah-Blah Blah-Blah BlahBlah! :D).

[Jecht_Sin]

And these are the performances.. I have used an interval of 5 seconds in "top" to get more stable values. Also the geek stats are always  active, to check the resolution since sometime it may vary.

2160p@30fps:

The CPU idle time at 60fps actually fluctuates between 20% to 50%. The microstuttering at 2160p@30fps is actually gone. It seems still present at 2160@60fps but it looks much smoother. This with the TV that rebooted an hour ago.

Oh, and as soon as I use the UI for something else (like simply changing the volume) the videos stutter. Especially the ones at 2160@60fps.

...annnndd I have just managed to freeze the app! It started stutttering like crazy and now it's just stuck. Closed it from the "app history" now it doesn't play any video anymore. This happened to me already days ago. I must reboot the TV... Oh well.

[Kuschelmonschter]

I can see The World in HDR now also at 2160p60. And I have never seen that before.

CPU usage has improved but is still more than 3 times as high as YouTube 1.3. Stuttering has improved but playback is still not always 100% smooth.

So I can confirm pretty much all your findings...

[Jecht_Sin]

Yeah, let's say at 2160p@60 they are watchable. Although at this point I'd rather have them at 30fps. At the end they seem smoother since I have no micro stuttering.

The good news is that now Google can improve the experience under the hood. When I've seen the 4K appearing yesterday in a typical 4K video I didn't believe my eyes. It took a TV reboot and now all 4K videos I checked play at 2160p, 60fps video included. And smooth enough. With 1.3.11 as we discussed already the 1080p@60 videos were getting stuck for seconds at the beginning.

Hopefully Sony/Mediatek will fix the profile vp9.2 as well, because as I wrote in the new thread I strongly doubt the lack of HDR in YouTube is a Google's fault (for once). It seems to me the vp9 Codec in Android 7.0 is faulty instead. And I have no idea how Plex manages to make it working.
