I will probably get a Sapphire Nitro+ RX 470 with 8GB VRAM in the next two weeks, so I will tell you for sure what is going on with Polaris HW decoder.

if you plan on buying an throw away UHD screen than get a card with 4Gb vram.

Btw Sonys Camp HDR Demo is also a 8 thread sliced Encode.

Should be also added as a Sliced Encode sample.

Sliced Encodes should be seperated for SMP Decoding tests though.

ok, thanks.
i'll waiting your review about Polaris HW Decoder.

@huhn

Btw did you tried Strongenes older non Polaris optimized OpenCL Decoder does it still work or does it falls back to CPU only Decoding ?

Why? 4GB is plenty of VRAM and I think we do not need this amount of memory when playing 4k videos unless playing the games in 4k res.
And, the best card is 1050 or 1050 ti currently. There are good advantages in 1050 over 1060 or AMD new cards, as you may know.

sorry reality looks different.

with my tests they need more than 2GB vram. if you want to make sure playback is smooth get 4GB.

it's 32 bit only can only decode 8 bit. it is slower than my CPU in lavfilter. it isn't using openCL (i don't see GPU usages) for what ever reasons.

and most importantly it crashes when i try to open the filter settings.
the openCL version is from 2014...

Latest NV CUvid with 375.xx drivers support P016 output and HEVC 12 bit decoding(not tested yet).

The cuvid/nvdecode library in the latest 375.20 drivers has support for both 12bit decode and P016 output surfaces - of course, these won't be documented until the next sdk release, but I've been habitually testing for it to show up and then it finally did.
Can't wait to see how Main12 hardware decoding works on Feature Set H decoder on Windows & Linux.

The PureVideo VP8 decoder of Pascal GP107 (GTX 1050 & 1050Ti) has already added 10-bit VP9 HW decoding support!!!

Btw i wonder actually if the GP107 VPX again has more native decoding features then maybe the GP104 VPX in the Nvidia SDK its mentioned that Specific Features are again only available on Specific Cards only (They don't explicitly state which exactly yet where) and i guess they mean the 1050 GP107 VPX especially once again with that

So they maybe did it again and GP104/106 (1060,1070,1080) user have not the full capabilities of the 1050 GP107 VPX

Which then means we would see those features in Big Size first everywhere with GVxxx again including most probably AV1 support

We should take a closer look at

GP104 (1070/1080)
GP106 (1060)
GP107 (1050)

and if something there is maybe again Hybrid or this time even non existing at all

@wanezhiling

I guess this is what Nvidia stated in the SDK with Specific features only on specific Pascal Versions

the last released VPX get normally the most features Gxx06/Gxx07

and the previous rather Hybrid CUDA based solutions (and this is really interesting if you calculate the user reach and target and overall Performance Metrics of their Hybrid Decoder Research)

I wonder if the Mobile Versions actually derive from it or if it's the same there, though they already balanced some stuff on the 3D side different compared to the Desktop GPU so i wouldn't be surprised if the Mobile support looks different.


I almost was very surprised that it this time it wouldn't be the case but then i read the SDK List and saw those footnotes

Amazing.

Cruncher is right.

From the figures it looks like Nvidia added a fixed-fuction decoder for VP9 10bit, in GP107 (1050/ 1050 Ti).

Of course Nvidia can surprise us and someone with a 1060 card someday finds out with the release of a new driver that VP9 10bit is enabled for those cards too.

https://developer.nvidia.com/nvidia-video-codec-sdk



Nvidia updated the Video Codec SDK page with Video Codec SDK 7.1 and more information about what Pascal Feature Set H decoder supports.

Can someone with GP104 or GP106 install the latest Nvidia 375.95 or later drivers and run the latest DXVA Checker to see if those GPUs support VP9 Profile2?

http://us.download.nvidia.com/XFree8...rtedchips.html

The page says Pascal GPUs all have the same Feature Set H decoder.

Doesn't mean much read the footnotes and it also doesn't explain how the Decoding is actually implemented that's entirely up to Nvidia

Quote:
* HEVC 10/12 bit encoding SW support coming in Video Codec SDK 8.0
** Max resolution support is limited to selected Pascal chips
*** VP8 decode support is limited to selected Pascal chips
Thats important but they don't say exactly which they keep it in the dark

Even as a Member you cant seem to access

https://developer.nvidia.com/video-e...support-matrix

currently

It doesn't say anything about VP9 10bit Profile2 support, don't need to be snarky and a troll.

No luck, same 375.95 driver

Ok, thanks, looks like Nvidia Volta GPU family top to bottom will inherit VP9 10bit Profile2 hardware decoding from GP107.

You really don't understand how VPX works.

Though 1070/1080 GP104 is not so important GP106 1060 is more important

It looks like GP107 has the most advanced video decoder right now, even more than Kabylake because i have never seen anywhere that Kaby supports 12bit HEVC which is the only thing missing though.

On the other hand, we have to see also HW encoding capabilities especially for HEVC and of course speed.

My opinion is that Kaby is faster than Pascal in all formats supported by both.

Also desktop Kabylake supports HDCP 2.2, it's not like Kabylake for laptops.

We'll see in less than two months.
