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

[madshi]

I can imagine Vulkan being a noticeable improvement over OpenGL, but I don't think using Vulkan would help either MPDN or madVR. AMD/Nvidia spend most of their time optimizing their drivers for Direct3D, so using Direct3D should offer the best performance - on Windows at least. Of course for a multi platform project using Vulkan sounds like the best solution.

Is there some evidence for the performance improvements? I really doubt this since the OpenGL renderer is doing absolutely fine with low CPU and GPU usage on both Windows and Linux (who knows about that crippled Mac environment which doesn't get Vulkan anyway).

What could be the reason if the player don't start? I just hear some error beep.

[Shiandow]

If it doesn't start at all that sounds like the issue is in MPDN itself, possibly some problems with .Net. Are there any messages in the windows event logs? You could also try running Debugview.

[stax76]

I've tried both but didn't find anything.

[Shiandow]

Odd, I'd expect at least something to show up in the event log. What version of MPDN and Windows are you using?

[stax76]

W10 Pro 1703 x64 and MPDN just downloaded.

[Shiandow]

Why is it always windows 10 with the weird .net issues? Anyway, reinstalling the .net framework might help, but maybe MPDN itself needs to be recompiled before it works properly on windows 10. In theory neither of these should be necessary, but then again in theory it shouldn't just crash on one PC and run fine on another.

[madshi]

It's also always Windows 10 with the weird GPU driver issues...

[stax76]

It's not that Windows 7 don't has issues... batch file processing is broken for instance if you use unicode and Umlaute, I need to deal with batch files for several reasons like x265 requiring piping or piping with eac3to.

Note there are serious implementation bugs in Windows's code page 65001 support which will break many applications that rely on the C standard library IO methods, so this is very fragile. (Batch files also just stop working in 65001.) Unfortunately UTF-8 is a second-class citizen in Windows.

Win 10 has it fixed along with 1000 other issues.

Maybe we have reached the maximum amount of code for humans to handle with windows 10 or something. Everyone seems to have at least one problem with it, but it rarely is the same. Did I just hear "minimal MadOS for HTPC"?

This definitely shouldn't happen. I don't know if it is related to .NET at all, never heard of something specific here, to be honest.

I don't know, anything unusual about your Windows configuration, programs running in the background that are not considered as "common"?

[stax76]

I use win defender and autohotkey with a simple hotkey script.

ApplicationFrameHost, AutoHotkey, backgroundTaskHost, Calculator, conhost, csrss, dasHost, dllhost, dwm, explorer, fontdrvhost, GoogleCrashHandler, GoogleCrashHandler64, googledrivesync, HxCalendarAppImm, HxTsr, IAStorDataMgrSvc, Idle, igfxCUIService, igfxEM, IpOverUsbSvc, IPROSetMonitor, jusched, lsass, Memory Compression, Microsoft.Msn.Weather, MSASCuiL, MsMpEng, NisSrv, nvcontainer, NVDisplay.Container, NVIDIA Web Helper, NvTelemetryContainer, nvtray, OneDrive, powershell, PresentationFontCache, RemindersServer, RtkNGUI64, RuntimeBroker, SearchFilterHost, SearchIndexer, SearchProtocolHost, SearchUI, SecurityHealthService, services, SettingSyncHost, ShellExperienceHost, sihost, SkypeHost, smartscreen, smss, SpeechRuntime, spoolsv, sqlwriter, StaxLauncher, svchost, System, SystemSettings, taskhostw, thunderbird, vmcompute, vmms, vmnat, vmnetdhcp, vmware-authd, vmware-usbarbitrator64, wininit, winlogon, WinStore.App, WmiPrvSE, WUDFHost

[Hrxn]

Windows Defender itself is definitely not the problem, and Autohotkey shouldn't be the culprit either.

But it seems that you have VMware running? Maybe that's locking the GPU driver in some way, I don't know..

[donger]

Is there any reason that after correctly using rate tuner i still have to delay sound 150ms to avoid lipsync issues?

[Shiandow]

Well, the most obvious reason would be that the audio on the video you're trying to watch is early by about 150ms.

Shiandow, hello! Can you tell me your preferences in scalers and shaders with MPDN, please? What things you use in different scenarios with various sources? Thank you!

With the latest extensions my default was Bilateral > SSIM > Deband Experimental > SSSR. All using the default settings (which shouldn't be too surprising, since I defined the defaults). I use this for pretty much all sources (although I heavily use script groups with shortcuts to switch between different settings or turn parts of the processing on or off).

However keep in mind that my setup is basically designed to test and improve the renderscripts I made. And that my version of the extensions might differ slightly from the current available version.

For example, one of the more recent changes I made allowed debanding to be done before chroma scaling (which is nice since you can work with the original 8 bit values). I've also added a shader at the end to convert from a 2.2 gamma to 2.4, since the current standards seems to suggest that SDR media should be displayed on a 100 nit screen with a 2.4 gamma.

well you missed something important here.

this only makes sense when your screen is perfectly calibrated to 2.2 but... just calibrate it to 2.4 if that is what you want.
and gamma should be chosen on room ambient light.

the current "standard" is BT 1886 BTW.

SSIM? As in SSIM Downscaler?

Well, I've seen/heard this before, but never found an convincing explanation so far. What is the point of the downscaling step? How does it really improve anything?
