Apollo Lake has no 10-bit VP9 ability, Gemini Lake does.

Just found out an ancient post of you (late 2015) at benchmark thread.
You owned that time a Skylake NUC and ran a VP9 DXVA2 benchmark too

The clip would maybe just barely run, but probably not quite fluid.

Pentium N3700 is not Skylake, thats Braswell, ie. an Atom core.
But I probably still have that one somewhere.

You're quiet right - it is in notebooks and its graphic core accelerates movies h265 4:2:0 3840x2160 24Hz (and may be 30Hz) well. But 50Hz and of course 60Hz (i.e. from SATs) bad.

I can explain my mistakes and never repeat them again.

I saw two VP9 device decoders in an old DXVA Checker screenshot for Apollo and I thought that one of them was 10bit, but no - it was just VP9 from Intel.

And I saw the benchmarks regarding hybrid VP9 so I thought we were talking about Skylake, but no - it was Braswell.

Both my mistakes were minor and don't alter the main meaning of the content that they were referring to, so I can live with that

And both Wanez and Nevcairiel are excellent debuggers (along with huhn) so the rest of the people can be sure that everything is properly corrected

nevcairiel,

I've ran into a couple of DVD problems using Lav Filters 0.73.1

DVD Audio Sample (at the menu play all)
https://www.dropbox.com/s/u2eiarh9an...Audio.zip?dl=0

There is an audio glitch (audio is delayed / distorted) during the start of playback when the ending credits play after the episode preview, going back to 0.71.0 fixes the problem.

DVD Subs Sample (at the menu play all)
https://www.dropbox.com/s/5qpf6qbnti...0Subs.zip?dl=0

The last subtitle lines displayed are stuck on screen during playback, The Microsoft and PowerDVD decoders work without problems. I've included the subtitle files with the sample in case that helps track down the problem.


Winows 7 64bit Pro.
MPC-HC 1.8.3 64bit EVR Custom Presenter S/PDIF Output.

Thanks.

VP9 hybrid works fine for Skylake and LAV Filters with the help of DXVA Checker tool.

You have to go to the GPU menu below left of the first screen and then to "Driver settings" and enable VP9 acceleration by setting ON instead of AUTO the VP9 Decode setting.

It seems that Intel disables VP9 hybrid acceleration by default in their drivers.

After the new setting, VP9 hybrid acceleration works for any app (DXVA Checker, MPC-HC etc)

Can anybody test 50fps 4:2:2 H265 20180428-175510_4K ENC 3 RMAD VS LEG.ts (563MB) https://yadi.sk/d/m0s5ztpj3XnUyw on RTX2080 with NVIDIA CUVID hardware acceleration (according to https://developer.nvidia.com/nvidia-...#NVDECFeatures - I hope ** 4:2:2 is not natively supported on HW just forget to remove from NVDEC section after Turing out - it may be accelerated successfully)? Btw theoretically must LAV Video Decoder be changed to support hardware acceleration not only 4:2:0 according to * The Video Codec SDK, which exposes new decoder improvements and features of Turing will be released soon... before or after that release (in new driver?)?

4:2:2 decoding is not supported in hardware.

How I understand this is Turing supports 4:2:0 and 4:4:4, but not 4:2:2 (or else it would in the table along with 4:4:4, which is only available on Turing).

I understand the same but it seemed very strange. And I hope this is just mistake jn that page - I need 4:2:2 hardware acceleration for SAT feeds - record of one of them I've mentioned above. CPUs that can fluently play that (like i7 or top Ryzen) are very expansive but i.e. RT(X)2030 must be cheap enough...

nevcairiel said there isn't hardware acceleration for it and that's it. There's no mistake, he would know.

There is or there isn't?
I agree with one thing - before Turing there wasn't any hardware acceleration for non-4:2:0 by any desktop videocard for home use (may be special videocards was able decode 4:2:2 because some very expansive SAT set-top-boxes support 4:2:2 decoding in their hardware).

Ryzen 2400G and D3D11 mode

Hello,

I have a problem with my Ryzen 2400G and D3D11 mode. In DXVA2 mode, no problem, the video is perfectly fluid. But in D3D11, the image seems to be raffrachied only once a second instead of the usual 24.

Anybody have this bug too ?

Thanks for your help.

@Nevcairiel

Two quick questions:

1) when a HDR metadata file has 0 for MaxMDL, do you replace it with a default value, and is that default value 1100nits? I'm asking because I get this value reported by MadVR on the OSD when the metatada reported on the disc is 0, fo example with Life of Pi US. Not a big deal but it would be nice to know for sure where it comes from.

2) For some titles, the metadata reported by LAV is changed to completely different values compared to what's on the disc. For example, with Goodfellas UK, the values on the disk are 247/60 for MaxCLL/MaxFALL, they become 500/200 when reported by LAV. I don't think this is a LAV issue because Mediainfo reports the same altered values when reading the mkv file, so it most probably happens during decryption, but I'm wondering if it could be related to some studios hiding a watermark during the rip of the disc in the metadata, as reported here: https://www.makemkv.com/forum/viewtopic.php?t=17008. Do you have an opinion on this, or have you come across it and do you have an explanation?

Thanks!

I just tried the opposite setting (by choosing the graphics card) and it works! Thank you for the advice but what is the difference between these two modes (Automatic (Native) and the other?)

Hey, Nev, are you aware of any more issues with ATMOS audio tracks? This is a Disney seamless branching UHD (Incredibles 2) that I'm dealing with. I've tried ripping it with two different pieces of software but the audio track is giving me all kinds of issues. It's far worse if I try to bitstream (audio cuts out completely at one point, restart the movie and have sync issues, pops where the audio drops and comes back, etc) than if I decode to PCM. But even PCM the audio has artifacts (pops due to audio drops, sync issues). I've tried with both MC and MPC-HC and I have pretty consistent results. Not sure if this is a problem with ripping the title but I've tried MakeMKV 1.14.1 and CloneBD and end up with issues with both. Thanks!
