Media Player .NET (MPDN) - D3D HQ GPU Video Renderer [v2.49.0/v1.31.0 27 Dec 2018]

[madshi]

And which practical benefits for end users would either of those 2 changes bring, foozoor?

[Shiandow]

I guess you could attempt to use the new DirectX renderer on an operating system that doesn't support Directshow?

[aufkrawall]

Async Compute might be able to improve performance with GCN GPUs, there is a pull request for a new Vulkan renderer of mpv which supports it.
However, there is no proof yet for actual performance benefits over DX11. I suspect it will be faster at some point than DX11 with GCN, question is just if it really will make a difference for advanced video shaders.

If I remember correctly, mpv Windows dev Rossi told me that there is an interop possible for D3D11VA -> Vulkan. So really no need for DX12, it's a completely redundant API.

[huhn]

did anyone even read what DX12 or Async Compute even does?

[aufkrawall]

There is no optimal GPU utilization without Async Compute, simple as that.
There are always utilization bubbles when the shaders process tasks serialized. Question is just how big they are.

[huhn]

and this is a video renderer.
it's pretty much about shaders. the benifit of async compute is most likely nothing at all because "only" the shaders matter no combination of other GPU parts.

[aufkrawall]

It doesn't matter that only shaders are involved for the fact that utilization isn't optimal. GPU is btw. also busy with other stuff like presentation, HW decoding etc.

[Shiandow]

I wouldn't expect any miracles from processing shaders asynchronously when 99% of the time MPDN is just rendering shaders at (hopefully) full speed, with little opportunity to do anything else in the meantime.

Unless you're telling me the GPU can process two shaders faster concurrently than it can process them sequentially, but that seems really weird.

[huhn]

yeah very unlikely it will do anything useful for video rendering.

Why not? That's also true for running tasks on the CPU with hyperthreading.
Games can profit by it the most (when they can utilize enough threads), but also other applications with constant high load like video encoding or ray-/pathtracing profit by it.

[huhn]

you can't compare a CPU multi threading with a GPU multithreading. a GPU has thousand of cores you can blindly assume they can multi thread fine.

the most profit from vulkan DX12 is the CPU which is a no issue here.

async compute is not made to utilized shaders better it is made to use shaders, rasterizer and other GPU part at the same time. while for video playback we are mostly using the shaders (correct me if i'm wrong here Shiandow).

if the shaders get better utilisation because the rasterizer are not standing in there way you can argue it is increasing shader utilisation but i don't see this happening for such a program.

Why wouldn't it just run the same shader twice on the left and right halves of the image?

Wouldn't that be quite an amount of work to adjust the shaders to work accordingly?
New Vulkan revision is not even mainlined yet, I guess more optimizations will come later.

No, by definition pixel shaders can be evaluated on any part of the image in any order. This is what allows GPUs to parallelize the process immensely.

In practice the GPU probably process small clusters of pixels in an orderly fashion, but the exact cluster shape and order depends on the GPU.

[TheFireRed]

I have a question: how can I leave this time code reader always turned on? Or I can only set the status bar to read this information?

[Shiandow]

I would actually recommend enabling the status bar as it wouldn't be in front of the video that way.

The alternative would be to make some small modifications to the extensions code. Nothing too difficult really, but it takes some work to set things up so you can recompile the extensions.

Have you guys tried uninstalling MPDN fully and reinstalling? Make sure you backup your settings before you do that. And try doing a windows restart after reinstalling.

Is there update about this bug?

Today i Installes it in my new computer and this problem still exit. i can't play any video.

My previous computer uses AMD GPU (RX 460) and the new one use RX 560. Is this bug only happen to new mid tier AMD GPU???

It looks like later versions of the .Net Runtime (in particular versions >= 4.7.1) might not have that bug, but this is not yet entirely certain. It's not related to the GPU by the way, it's purely .Net / Windows that's causing it.

You are right. After update .Net Runtime to version 4.7.1, i don't need to downgrade MDPN.

Thank You sir
