Well, it seems to make a difference when pausing files with lossless audio. Perhaps clsid can explain it some more. After all, he made the change
Or not LOL I'm just happy it works now, regardless of what fixed it. If it makes any difference, none of my files are local, so in essence everything is streamed.

@nevcairiel, does LAVVideo decoder support HLG HDR? Sample
The output PIN info states: "VideoTransferFunction : 5 (BT.709)" I'm asking because of madvr and this. Cheers

Indeed, madVR does not support HLG, and the HLG VideoTransferFunction function was used for a special madVR value in the past, hence with madVR it maps it to another format. Other renderers should receive the HLG flag (16), and they can then deal with it.
Sending the HLG flag to madVR would not give you anything good until madVR learns to deal with HLG. HLG is very different from HDR10, so no just masquerading as the same and somehow work.

Thanks for the confirmation, I missed the part somehow that it's working with e.g. mpcVR (otherwise I wouldn't have asked it), sorry
Do you know any directshow renderer that can output HLG in HDR10 properly? Just noticed that e.g. VLC does ...

@Nev, sorry to bother you but it would be nice if you could look into something.
As you may have heard the latest test build of MadVR caused playback issues for few users but an OS and/or driver update fixed it for most of them. Unfortunately I still have the issue and I blamed my hardware and waited for a fix from Madshi. However, the devs of MPC-BE are currently improving their own renderer and I wanted to look at it and was surprised that there is the same problem ! Issue : A file plays with sound but there is no image just a green (madvr) or black (mpcvr) screen when using LAV video decoder in D3D11 Native mode ! It works with every other setting but then I have performance problems, especially on 4K HDR. Is there maybe anything broken in native ? |

Which GPU is that and which driver? Take a look at my signature, those work fine.

Tigerlake AV1: https://imgur.com/a/SR95o3C
D3D11 AV1 hardware decoding works, DXVA2 is corrupted. Tested on newest LAV and MPC HC. |

I already did here: https://forum.doom9.org/showthread.p...58#post1929258 For some reason I cannot check D3D11 decoding performance from LAV in DXVA Checker: https://imgur.com/a/T1uJqZf On a further note the inhouse Windows 10 player with the Microsoft AV1 extension works better, there is basically zero CPU and GPU load while playback (with Firefox running background): https://imgur.com/a/nKGVknN And this is from MPC Home Cinema and LAV D3D11: https://imgur.com/a/zh0ELEC 1W more IA cores usage and it uses the GPU in addition to Video Decode and Processing. I'm using the AV1 4K Summer Nature sample from here: https://www.elecard.com/videos Last edited by Yups; 20th December 2020 at 09:47. |

DirectShow does not natively support D3D11, so we invented our own interface to do it with reduced overhead. DXVA Checker does not understand that. Neither do most video renderers. If you want to test full native D3D11 playback, you need to use madVR, or maybe mpcVR, which I believe supports that as well (none of which come natively with MPC-HC)
Of course you would have to make sure that the renderer then doesn't use additional resources, for a fair comparison. DXVA2 not working sounds like a driver issue to me, the data being provided to the hardware is the exact same, even generated by the same code, for both DXVA2 and D3D11. Of course I cannot tell either way without access to hardware, and until cheap-ish NUCs come out, thats out of the question.

Can you confirm Intel QuickSync, DXVA2 and D3D11 hardware acceleration with TigerLake and LAV Video Decoder 0.74.1.92 while playing recorded from SAT feed 4:2:2 h265 4K 50fps file 20180428-175510_4K ENC 3 RMAD VS LEG.ts (563 MB) https://yadi.sk/d/m0s5ztpj3XnUyw and youtube 8K AV1 60fps file you can download I've described here https://forum.doom9.org/showthread.p...84#post1903584 Please provide CPU and VideoEngine load while playing both files. As I understand there isn't Win7x64 driver for Intel Iris Xe graphics - am I wrong? |

There is no 4:2:2 hardware acceleration in DXVA2 or D3D11, and QuickSync in LAV is dead and likely to be removed.

LAV doesn not support 4:2:2 by the looks of it and your AV1 sample is 4K only, not sure this is what you ask for. Intel does not support Windows 7 anymore. |
