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

I'm getting this error when trying to configure script chain:

"Object reference not set to an instance of an object"

Any thoughts?

[Shiandow]

Could you try updating the renderscripts and deleting the Script Chain config file? There was a bug in the previous renderscripts that deleted the settings before saving them, this made the settings invalid.

The download section is extremely non-intuitive that it has prerequisites.

If you don't believe me put a 3rd party to review that for you.

PS. The main problem is LAV. Most people nowadays do not have it installed (mpc-hc has a very up to date version built in). At the same time this program does not even report it missing.

No, but I'm sorry if it sounded like it was a sarcasm. I was just trying to be sure it's not a bug or something else that you needed to fix before it would run. You didn't mention anything about prerequisites in your post.

I'm aware of that issue but it's a project that we do on our free time and at the moment it's really missing an installer. At the end of the day there's only so much time we could spend on it. Belphemur was going to do an installer for MPDN but he's got other things he's working on as well.

How do I do that?

Delete and recopy the extensions folder from where you have MPDN installed to make sure your renderscripts are up-to-date.

Change the driver letter and "yourname" in the example below to match where your profile.

C:\Users\YourName\AppData\Local\MediaPlayerDotNet\

Delete the Mpdn.ScriptChain file in that directory.

Thank you that did it!

@animeviewer I'll try to create a debug version of some sort so you could find out what was causing the hang. Maybe I could build the feature in there such that it detects lockups even in release builds. I'll see what I can do.

Oh sorry then if I were too "premptive". I'd probably just do a small check before rendering and report "LAV not found", that should give a hint to anyone even barely familiar with video players.

If it's hard to detect LAV's presence, fine. I do not know much about coding for video players.

This has been brought up a couple of times, It has caught me out on one occasion but figured it out quickly enough, and there is always "read the OP"

Doesn't it show the error that goes like this?

Load source failed

Hint:
Make sure LAV filters are installed

[Belphemur]

As Zach said, I decide to take on creating an installer for MPDN that bundles LAV, XySubFilter, the github extensions and of course the player.

I made a first version that is in BETA, only tested on X64 (but should work on x86). : http://mpdn.zachsaw.com/Installer/Me..._Installer.exe
It contains the last version of MPDN (v2.26.0) and the version of today Player Extensions.

The installer detect automatically what is your architecture and if you chose to install XySubFilter, it will also register the right version for the player.
The Installer of LAV Filter is embedded into it, if you choose to install it, it will launch LAV Filter installer.

I still have to do more testing when upgrading from one version to the other, especially with the Extensions.

Any feedback is welcome.

I continued my comparison with madVR (+MPC-HC).
I don't know if you like this kind of post, and if it upsets you, tell me, but I though it would be interesting to compare this player with a known alternative.

With my ATI 5770, I told you CPU was higher with MPDN.
With the same config, except using integrated Intel GPU (HD 2000) instead of ATI card (unplugged), MPDN still uses a bit more CPU, but is is less pronounced, and it uses less GPU.
That lets me think GPU cards have an incidence on differences of performance between madVR and MPDN. I remember my ATI 5770 is known to have bad performances in some area (Madshi had released a little tool to measure differences between cards). It looks like you don't use the same way to "speak" to system to have the final image.

I also tried on another system, and with a NVidia GT 430, MPDN had slightly better results (CPU & GPU).

For the startup, I don't know if you can do something or it's just DotNet stuff, but MPDN takes several seconds (depending on system but still second is the right unit) more to start the video than MPH-HC.

Another thing I've noticed is MPDN statistics OSD cost CPU whereas madVR OSD uses 0 resources.


And an anomaly to finish this boring post: dropped frames are not reported on FullScreen Exclusive (I use D3D9).

Hope you won't take it the wrong way and it was just a try to help you improve this player.

Could be in part related to the fact that MPDN's OSD updates at least five times faster than madVR's.

Hey Zach,

Do you mind sharing the ff:

1. The hierarchy of your render scripts. Which comes first, middle & last as well as their respective settings
2. Your chroma & Luma scaler & down scaler preferences

It would be awesome to see how experts like you are setted up

Thanks a lot

Unless its using up CPU/GPU to the point of causing resource problems on your system (where you can't do other tasks or watch video on your system successfully) I don't see why that is a problem. If the GPU and CPU aren't being used that could mean that their workload may be getting dumped off to slower parts of the system for handling (like system memory - which can be slower than video memory, or the disk drive - which can be slower than memory - SSD can be excluded from this occasionally).

Are you talking about when it says: "optimizing extensions", or are you talking about something else? You could always turn off extensions (and delete that directory to speed things up), but then you'd loose out on features.

Do you plan on watching entire videos on a regular basis with with OSD on the entire time? I doubt it, so what does it matter if OSD uses a few resources when you aren't going to have that active normally?

Are you saying your system is dropping frames (where you notice on screen problems)? If not what is the problem? If its not dropping frames that is a good thing.

Not all settings can be configured identical for both, so they can't be compared apples to apples.

I think you're getting too wrapped up in insignificant things. The most important things is: Which is giving you better image quality? Which has the features you want to use?

As they both stand I feel MPDN is currently providing the superior video picture on my system, and is why that is my default video program.

I'm probably not the best to ask since I'm still running an older version of MPDN on my HTPC (hence an older version of scripts too) - been spending way too much time developing MPDN it's getting in the way of my enjoyment of my own creation!

I'll say this though, it's really up to you and the contents you view, as well as how much your GPU can take (or GPU fan noise you are willing to put up with).

I've just released 2.26.1, specifically targeting this problem (app hang). It *should* detect the situation where MPDN becomes unresponsive and causes a crash on purpose (after several seconds). You'll get a crash dump file in %localappdata%\MediaPlayerDotNet.exe.dump.

p.s. Thanks for helping out in the forum!

[Zachs]

Ah found a bug with the latest version. It'll crash when it exits. I'll fix it in the next release.

EDIT: Fixed. v2.26.2.

Which hardware decoder works best? cuvid or dxva2?

Is it possible to have 16bit in windows mode? I'm only getting 16bit in FSE

No, anything above 8-bit requires FSE.
