I'm pretty sure that 10bit hybrid results will be better too.

I'm very interested in your RAM downgrade results to 2133 MHz (default for Skylake) to see how lower could be in SW decoding and maybe HW too compared to 3000 MHz.
Yes, those would be great to test + No Hyperthreading
I wonder if i5 6600K can handle 10bit well too.

Can you retest this too, in order to complete the picture:

1) LG_4K_View-the-Feeling.mp4 - 4K@30fps - 25Mbps

The platform is very young and those fluctuations are expected.

I'll keep the previous results of clip 1 in order to be inline with the others.

Unless you want to rerun the tests for the rest too or you tell me that the others didn't change.

@Yups

Using latest DXVA Checker v3.70 and your HD 530, if you go to "Check Decoders" -> "Select Format" and you choose VP8 or VP9, are there any other decoders besides LAV ?

I'm interested in Intel MFT VP8/VP9 decoders that using previous DXVA Checker v3.60 were enumerated by choosing VP8 and VP9 formats.

Also, if you have a VP8 or even VP9 sample (any sample) can you check with your system and latest DXVA Checker v3.70, if any Intel MFT decoders appear when you choose "Select Media File..." and test a VP8/VP9 file ?

Thanks!

Are upcoming 4K Bluray discs 10bit or 8bit?

10 bit (UltraHD TV and UltraHD streaming are also often 10 bit already)

No decoder listed. I don't have VP8/9 samples.

But the image shows clearly Intel's VP9 decoder

If you select VP8 format, does Intel's VP8 MFT decoder appears ?

I'll upload two samples later, one VP8 and one VP9 to test the "Select Media File"

VP8 shows exactly the same.

Weird...It should say VP8 according to the previous version of DXVA Checker and according to the installed decoders.
Unless of course it is somehow common.

I did it for HEVC but got no HEVC_VLD_Main10 for LAV:

Does it only show native DXVA? Then you might need a recent nightly version of LAV.

Guys isn't time to test HW accelerated HEVC encode?
It is present on Skylake and NV Maxwell Gen 2 GPUs (yes even my GTX 970 which doesn't support HEVC decode)..
One way to test will be ffmpeg which supports using NVENC for Nvidia support and QuickSync for Intel..
We should make standard binary and command line args with a standard video input too similar to h264 benchmark (Tech ARP - x264 HD Benchmark Ver. 5.0.1)..
Then let the benchmarks begin..

I have been thinking of this concept since last August when I purchased my Core i7 4790.

But most people are interested in SW encoding and particularly SW quality encoding, not speed.

So, a very specific benchmark test regarding speed of HW encoding and expecially HEVC, which is so immature right now, it doesn't make a lot of sense to me.

But you are free to open such a thread, I don't think there is something like that in this forum.

I know only a quality comparison thread between x264 and x265.

It's kinda useless since SW encoding provides better quality and nobody wants to encode in real-time on PC.
