Post a link to your 4k VP9 videos and I'll try to view them.

This is a link with all of my samples listed in a server with a max download of 1MB/s
ftp://helpedia.com/pub/multimedia/te...ecoders_clips/

Take a look here:
ftp://helpedia.com/pub/multimedia/te..._Ex_sample.mp4

It's a 8K sample with only 133MB footprint on your disk.

I would like also you to test this 4K clip with huge 700Mbps bandwidth.
It's only 787MB, take a look here:
ftp://helpedia.com/pub/multimedia/te...it_700Mbit.mkv

OK, here is a link of YouTube with 4K60fps in VP9 codec:
https://www.youtube.com/watch?v=ppy_gjBp71E

You have to manually select 4K60 fps from the "Settings"->"Quality" -> 2160p60 (4K)

Now, regarding your tests and your DXVA Checker screenshot, it seems that you have the full-featured video decoder of Pascal 1050/1050 Ti chips regarding features but the decoding speed of 1030 is between AMD RX 470 and Nvidia 960.

Something like that: (regarding decoding speed)
RX 470 < GT 1030 < GTX 960

Your 2GB VRAM is a no go for Netflix 4K streaming, which requires >3GB VRAM

Also, as others have already mentioned here, using madVR with 4K content requires >2GB VRAM, especially for the clips you mentioned to test like "Exodus" and "Life of Pi" clips which are HDR.

Did you find the "GPU Video Clock" ?

Thank you.
The GT 1030 is enough to play 4k HEVC HDR 60fps video.

why should there be a problem at FHD?

Wanted to update this to say that YouTube HDR clips are also playing in Edge in HDR if you turn on HDR mode in Windows (and you have an HDR TV/monitor, obviously).

In "Stats for Nerds", Codec is reported as VP9.2 and color is reported as smpte2084(PQ)/bt2020.

This as of Windows 10 Insider Build 16232. Not sure if it works on any earlier version.

Notably, on my 1060 this seems to be using hybrid acceleration and at 60fps drops frames like crazy. It can mange 24fps (at least) smoothly, though.

Only 1030/1050/1050 Ti cards have fixed-function HW decoder for 10bit VP9, used by YouTube for HDR clips.

And Kabylake from Intel of course.

I think 1060 doesn't even have a hybrid 10bit VP9 decoder.
It must be CPU only.

The 1060 DOES have a HW decoder.

We are talking about VP9 10bit.

Are you following the conversation ?

[v0lt]

@jmonier
GTX 1050 vs GTX 1060
The GTX 1060 does not have a VP9_VLD_10bit_Profile2, but it does exist in the GTX 1050. Need or do not need this feature, this is another question.

[NikosD]

Latest Nvidia drivers are out - 384.76 - and it seems that Nvidia kept its promise, eventually.

They added support of DX12 on Fermi cards, although it's just support not optimized drivers for DX12.

[NikosD]

OK, it seems that 384.76/384.80 drivers of Nvidia, enabled one more undocumented feature - besides DX12 support on Fermi - and that is Netflix UHD support on Pascal cards.

If someone has a 1030/ 1050 which have <3GB VRAM could try a Netflix UHD account and tell us if it works.

You need Netflix Windows Store (UWP platform) app or Edge browser, Windows 10 and HDCP 2.2 4K monitor.

It is the first time I see Video Decoding usage of Intel's iGPU outside of Intel's own tools (GPA monitor)

I can't find anything in GPA monitor

[NikosD]

Do you have GPA monitor installed ?

It's a special tool from Intel, it's not in the drivers.

You have to read the manual.

Yea but it doesn't show video engine load, only fps.

I tried out using the Skylake IGP for decoding with rendering and signal output via dGPU, and it worked like a charme on Linux with mpv and vaapi-copy (mpv btw. worked great in general with the IGP on Linux).
On Windows, we are still limited to the old QuickSync decoder in LAV Filters which doesn't support HEVC 10 bit and VP9, right? So Kabylake users with dGPU are cut off their best video functionality...

[NikosD]

I think that DXVA copy-back can do that using recent versions of LAV filters, but nevcairiel should reply for sure.

[nevcairiel]

You can do that if the GPU is active. It needs a connected screen for that.

Only D3D11VA-CB could do that, but nev stated it'd be really ugly for him to implement.
mpv has D3D11VA-CB support, but it's slow and it seems to be lacking support for using different devices.

It wouldn't be enough to simply add a second cable that connects the display with the IGP and dGPU at the same time, right? If I'm not mistaken, there needs to be an actual signal send to the display?
