what is the difference you measured ? Microsoft had this already with Windows Media Player for Windows 8 implemented since the beginning part of the new Media Foundation ?

Difference in what? Chroma quality? That depends on the GPU (drivers) and is not really "measurable". Speed should be similar to native DXVA2, maybe even a tiny bit faster (not sure). Quote:
I rather think. though, that Windows Media Player probably asks D3D11/DXVA to directly convert the video to RGB, in which case you get chroma upscaling quality depending on GPU drivers, and no access to any custom scaling algorithms. In that case accessing luma and chroma channels separately probably was never used by Windows Media Player. Last edited by madshi; 17th September 2017 at 10:04. |

[QUOTE=madshi;1818726
Have you tried resetting madVR to default settings, and then re-enter the necessary settings like 10bit display bitdepth and D3D11 presentation? I'm asking because you have some somewhat unusual settings, like D3D11 presentation, but without the "present a frame for every VSync" option active, and with "present frames in advance" unchecked. Also, have you tried FSE mode? Which media player are you using? And you didn't remove the "amd_ags_???.dll" files, did you? Your AVR only reporting 8bit even though the madVR reads 10bit is an ominous sign. It should really be 10bit. [/QUOTE] Thx for the reply. I have tried reset default, new windows install... (madvr version 92.1 .2 .3) "present a frame for every VSync" (i was thinking a while back someone stated, this must be off for HDR) on and off makes no difference "present frames in advance" unchecked.(i had this off all wayback, to gain faster zapping times in DVBViewer) testet with on and off makes no difference. FSE on or off no diff. HDR let Madvr decide or pass. no diff. I am using DVBViewer latest Version. i did not remove those files amd_ags_???.dll, both are in the madvr folder.(should i ?) One thing i was see, when i manual put 10bit Desktop, normal 1080/720 is output 10bit(AVR report BT2020, Colors are borked) when i start now 4K/23Hz HDR BT2020 File, its now 10bit 2020 but no HDR. if i switch to 4k/50HZ BT709 TV stream -> its 4k50Hz 8bit.(osd says still 10, but AVR now says 8bit). i have also try´d now without AVRm direct to TV but still the same no HDR. Another Question, over testing i was seeing Travel 4K Channel on Astra who is HLG Testchanel (4K 50Hz BT2020, HLG) i guess there is no support for now. OSD did not show a sign of HDR. If you need me something to test, just let me know. Last edited by Jasch; 17th September 2017 at 10:49. |

At least on NVIDIA, I think D3D11 deinterlacing should be of better quality than DXVA2, because DXVA Checker reports it uses more past and future frames to analyse the interlacing with D3D11VA, so we might possibly get better quality with Native D3D11 deinterlacing when it's implemented. Yes I've seen there's been a new test build, thanks!

Yes, if I toggle that option the picture dims or lights up. I think my problem is that I'm not seeing the Wide Colour Gamut colours -I'm just seeing rec709 colours with hdr. Just tested a 'Patriot Day' sample, and I'm getting the same problem. Many of the colours that are visible using the TV's own player (via usb) are not visible on PC with mpc-hc+madvr. I also tried with everything set to 8 bit and no dithering in madvr, didn't make any difference. Last edited by mrmarioman; 17th September 2017 at 13:27. |

Doesn't work. Nevever worked. Cleared out MadVR several times. Been through a few driver updates and now a change of GPU (RX 480 to RX Vega 56). Still the same issue. Private AMD does not work to auto switch to HDR. It just plays HDR converted to fake HDR colors when HDR is switched off in Win10 display settings. I don't have HDR switched on by default. If I switch HDR on then HDR works but ONLY with FSE unticked. If FSE is ticked I get washed out colors. I have yet to see an AMD GPU owner state that HDR is correctly switching with HDR turned off in Win10 settings and FSE ticked. But please do chime in if anyone has. To get correct color output (with HDR switched off in Win10 display settings) I either have to set 8 bit in AMD Relive, MAdVR or just set MadVR to Rec 2020 colorspace. I wish you had a recent AMD GPU and HDR UHD TV to play around with so you could see what is happening. |

Another totally different problem: madVR never manages to optimize my custom rates. I follow the instructions, play a video at that resolution for 30 minutes or more, but when I click Optimize again I get the original popup, never the analysis results popup. I'm using a native driver for the monitor, using a GTX 1060 with the latest driver. EDID is read with no problem. Last edited by jkauff; 17th September 2017 at 14:13. |

Maybe there are differences and I can't just see them with my limited samples. However, even with a few videos, the advantage of YADIF seems uncatchable. |

There was a test sample lurking somewhere on avs forums some years ago, it had moving text + stacked up lines all over the place. I remember running it to compare my SkyLake iGPU vs AMD deinterlacers, AMD had better results. I am not sure if this test video should be taken seriously when comparing and in any case i never had an NVidia card to run the test there. Is it possible to double the frames with YADIF? Hardware deinterlacers always double the output. |

YADIF allows to choose between film and video mode (LAV Filters offer this).
YADIF: DXVA2 Nvidia: It's frame 480/960 of the H.264 interlaced sample offered by the Kodi page (I however reencoded it as interlaced because the original sample doesn't meet hardware decoding specs). YADIF isn't perfect here either, but that aliasing of GPU deinterlacing is just devilish... |

I tried the new D3D11 decoder on LAV (0.72.2.74). On a perfectly running setup of DXVA2 copyback, just changed it to D3D11 and left hardware device at automatic. MPC-HC (1.7.13-x64) now launches and madvr resolution change kicks in, but the video doesn't play at all. Just stays paused. Ctrl-J doesn't work. Even if I go into windowed from FSE, it stays paused and doesn't play. What am I missing please?
