They work for me on Windows 7 with MPC-HC/BE + madVR or EVR CP.

Daicon said he was on Windows 10 and needed to install DirectX.

What you select and what is actually being used might differ (software fallback). To check see what LAV Video settings of active instance state as "Active Decoder: [...]" and "Active Hardware Accelerator: [...]". In madVR OSD the decoding queue indicates whether video decoding is fast enough (queue always full or nearly full) or not (queue low/empty).

LAV Video Decoder and...

1. No frames dropped.

Hardware Decoder to use: D3D11
Active Decoder: d3d11 native
Active Hardware Accelerator: Intel(R) HD Graphics 620
Hardware Device to use: Automatic (Native)

2. Frames dropped.

Hardware Decoder to use: D3D11
Active Decoder: d3d11 cb direct
Active Hardware Accelerator: Intel(R) HD Graphics 620
Hardware Device to use: Intel(R) HD Graphics 620

3. Frames dropped.

Hardware Decoder to use: D3D11
Active Decoder: avcodec
Active Hardware Accelerator: <none>
Hardware Device to use: NVIDIA GeForce 940MX

...so what we know more now?

Sincerely

The result is as expected: Kaby Lake can decode the video (fast enough) and with native D3D11 there is no bottleneck copying frames from/to RAM. So with 1. any remaining slowdowns should be because of too demanding madVR processing.

Thank you for your fast reply.

So there should be no problem with Intel NUC 8th Generation either? There is Intel Core i5-8259U with Intel Iris Plus Graphics 655.

With DXVA2 Native or D3D11 Native decoding, and low madVR settings, you can play stuff surprisingly well on NUCs. So yeah, it should be mostly fine. Just don't expect too much from madVR, since the GPU is weak.

I would recommend to wait until Q1 of 2020 for Intel's Elkhart Lake with Gen11 Graphics !!!

Hi, my player has been crashing lately when I try to play movies from my laptop connected via hdmi to my onkyo receiver, this is my madvr crash report:

Yes thank you.
HDR now looks better, but SDR is oversaturated, even with DCI-P3.
And more trouble - the rendering time has increased 2 times (30->60ms) on my Vega8 (Ryzen 3 2200G)

Try setting calibration to BT.2020. Some AMD drivers do strange things to the color space.

This was posted at the DSPlayer forum. I'm not certain if it works or will bring back functioning stereoscopic 3D playback to Nvidia, but it might be worth a try:

Slightly corrects the situation, but not completely.

This shader is only useful for converting the gamut from a BT.2020 HDR source to Rec.709 or DCI-P3 when using passthrough. You should not use it in any other situation. The increase in rendering time surprises me a lot, much more demanding shaders only take 2-3 ms in a 1080 with 4K @ 60fps. Create a folder in the madVR installation folder with the name "ShowRenderSteps" to confirm in the OSD that it's because of the shader.

Thanks! That could be very useful.

Is there a way to automate the process depending on the source?

I don't think so, only in terms of the resolution, but anyway why would you want to do something like that for the SDR? You can use madVR for that and it would not take that much rendering time.
The rendering times are very large, I guess that's normal for your GPU.

Delete the ShowRenderSteps folder if you don't need it, because it will slow down the overall rendering time when the OSD is being displayed.

check your Vram.
19 ms for a trivial task doesn't make sense.

what is this custom shader anyway?
there are so many ways to fix color issue with madVR none of them should be this slow.

Maybe because I use APU.

To fix a issue like this.
For example? madVR -> calibration does not help.

a 3d LUT should only take a couple of MS.

and it doesn't matter what GPU you are using a simple range conversation shouldn't take longer then the minimum of about 0.3 ms even an old Intel igpu can do such a task easily. on the other hand AMD APU are one of the fastest iGPUs out there.

you are currently not using an native decoder and the main reason i don't like to recommend AMD apu is that they are limited to 8 lanes of PCIe.

what so ever check out GPU-Z
