Windows 7 does not support D3D11 decoding, its as simple as that. You can search the thread for when D3D11 was first introduced in LAV for more detailed explanations which features are unsupported in 7.

Thanks, but is not as simple as it looks like because it's module from DXv11 and DX11 is supported by Win7. Anyway it looks like now Win8.1 is the best option, and its time for next step.
ps. I Think that "Platform Update for Windows 7 SP1" solve this issue. |

You basically need 11.1, which is not available until Windows 8.
For reference: https://msdn.microsoft.com/en-us/lib...sktop/bb173059 - look for DXGI_FORMAT_NV12 Quote:

I don't memorize every single generation of hardware. Its quite possible that it is not. I believe Skylake was the first to add full HEVC/H265 hardware acceleration (8-bit only, 10-bit hybrid), so that would be a no then.
This page seems to agree: https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video

https://frupic.frubar.net/36394 So, I moved back to Win8.1x64 and there the outcome was the same. Even with Intel driver .4821. (Later I even set madVR back to Auto; if I just start the film and do nothing, it runs ok; but as soon I "FF" or go with the mouse over the seek-bar everything breaks down) So, my question is : is qualitywise the outcome of the “side-by-side” trick in madVR the same as with “auto” (are 2 full HD pictures sent to the TV which it combines to a 3D)? --- Then I followed a different thought : basically all MVC-files should be the same (right?) – a H264 base video and the ssif-stream are muxed with audio and sups to an mkv… why are some played and others not…? Of my 65 3D-movies 28 work with LAV .83 (using hardware decoding) the others not. What’s the difference? Since my expertise is limited in this area, I simply used MediaInfo… The differences MediaInfo reports are only in: “Multiview layout laced” (present or not present) ReFrames : 2, 3 or 4 GOP : M=1, with N= 5, 7, 10, or 12; or: M= 3, with N=9, 12 or 24 https://frupic.frubar.net/36395 Generally said the outcome was unfortunately inconclusive; this are the trends : Of the working files 2/3 had Reframes=2 and GOP =M1, with N=5 or 9 or 10; or it was not set at all; Some had Reframes=4, mostly with GOP = M=1, N=12 or M=3, N=24; very few has Reframes=3; Of the not working Files 78% had ReFrames : 3 with GOP : M=1, N=12 (70%; only one exception : N=7) or GOP not set at all (30%); …maybe there is something completely different one could look for but I don’t have the knowledge and tools…? But bottom line is : I should move back to the madVR thread, right? |

Maybe you upload short sample of "bad files" for testing.
