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

[Shiandow]

I am very happy that after my suggestion to use the finesharp shader you have been considering to make it work better. thanks!!
For my setup is probably the best method of sharpness.

A little suggestion, is possible to implement various chroma resampling filters as Robidoux, blackman, Gaussian and Hermite?
Some of them are simlpy interpretation of bicubic style resize.

The renderscript files on github (https://github.com/zachsaw/RenderScripts/tree/master) now include a new ChromaScaler render script which supports Robidoux, Hermite, Mitchell-Netravalli and all other Bicubic resampers that belong to that family. If you want it even allows you to specify the parameters yourself so you can fine tune it however you like.

The filter currently uses Elliptical Weighted Averaging, which should improve the quality but I'll probably add a 2-pass mode later, so you can sacrifice some quality for performance (this might be needed to handle 4k, especially on older GPU's).

For a more detailed explanation of the family of bicubic resamplers that this scaler can use see this page (http://www.imagemagick.org/Usage/filter/#mitchell).

If you want to fine tune the parameters (called B and C) here is the result of a survey image processing experts examined the effects of different values of B,C:

Interesting read. If I'm reading that right then its saying that for watching line drawn content (cartoons/anime) Mitchell is often the preferred upscaler, and for real-world (people?) Jinc is the preferred upscaler. While for shrinking Jinc and Lagrange are the preferred downscalers if ringing insn't a concern. I've been using Jinc in the past for both up and down scaling in MPDN (and Jinc (up) and Catrom (down) in madVR), but I do see a reduction in artifacts with Mitchell compared to Jinc with drawn images (just as the article mentioned). Looks like I'll have to consider varying the settings depending on the content I choose to watch. Maybe I'll set the MPDN 32-bit one way and the 64-bit the other way. Using one to view drawn content and the other for live content then settings wouldn't have to be reconfigured before watching different content.

Maybe I'll set the MPDN 32-bit one way and the 64-bit the other way. Using one to view drawn content and the other for live content then settings wouldn't have to be reconfigured before watching different content.

With v2.9.5 passing VideoFileName (full path) to render scripts, you'd be better off writing a chain script.

What you could do for example, is if your hand drawn contents are in a particular folder, you could easily write one script that uses certain scaling algo by checking to see if the 'VideoFileName' file is located in that folder, and then a different branch (simple if-then-else will do) for a separate algo for your live contents.

Or if you are more adventurous, you could even put all your file names in a text file with a lookup table that tells your script what sort of content it is.

Have a look at MyRenderScript.cs on github for an example.

By the way, Mitchell is equivalent to MPDN's Bicubic with sharpness set to 66. Bicubic@100 == Catrom.

Edit: issue resolved with the latest script upgrade.
Edit2: when playing 1080p video with the current script, entered windows mode from full-screen mode, the video gets dark, looks like the script chain failed to adapt target size changes.

I just tested this and it's working fine going both directions (windowed -> exclusive full screen mode / non-exclusive full screen mode, and back from either one).

This is with MyRenderScript.cs?

Yes I was using MyRenderScript.

Indeed, looks like I was using an intermediate version. The bug gone with the latest script.

Edit1: without the size double function, now the IsUpscalingFrom(chain) in MyRenderScript not not doubled after adding NEDI to the chain somehow. I spotted it when trying to apply NEDI multiple times, which caused MPDN to crash due to infinite loop.

Hope it be fixed soon.

[Scyna]

Any update regarding XySubFilter being added? This is the only thing stopping me from making this player my main.

This is because of some changes to the way RenderScriptChain's work, which is still somewhat experimental. It basically tried to append NEDI to itself, which created an infinite loop. The older method didn't have this problem, but was somewhat less elegant, with any luck these problems should be solved soon(ish).

[Zachs]

Any update regarding XySubFilter being added? This is the only thing stopping me from making this player my main.

I've got the C++ shim to support XySubFilter done and the player itself can now receive the frames from filter. What is still missing is passing that subtitle frame to the renderer to be combined for final output.

A little tied up with the RenderScript system at the moment. Hopefully I will have some time to finish XySubFilter support soon.

What could it be? :confused:

[Shiandow]

Apparently there's a mistake in one your render script files. Were you trying to write your own? If not, could you try replacing the render script files with the ones on github?

Edit: Zachs seems to think it happens somewhere else in the code. Since he knows the code better than I do he's probably right.

[Zachs]

Hmm from the stack trace it seems like one of the DirectShow filters has a corrupt entry in the registry. I wasn't expecting that at all so I'll put some guards in the code to silence the error.

EDIT: Confirmed. This is due to one of the filters in your registry specifying an invalid CLSID (i.e. not even in the form of a GUID value). I've put a check in the code to skip these entries and will be available in the next MPDN release.

As a Windows programmer, I'd say always assume the registry is full of invalid, missing, corrupt, and/or plain-wrong entries.

Really looking forward to the further maturation of this player :)

Any update regarding XySubFilter being added? This is the only thing stopping me from making this player my main.

v2.10.0 has *experimental* XySubFilter support.

I haven't tested it enough with different materials and subtitle formats etc. So please report bugs with screen shots and a small sample of the video if you find any problems.

To enable this experimental feature, you'll have to run v2.10.0 once. Then close MPDN. Go to your app config file (see OP for the location), search for "UseXySubFilter" and change the value from False to True.

v2.10.0 has *experimental* XySubFilter support.

Are you remembering to use 'premultiplied' alpha blending?
Some things such as blurred edges which should be semi-transparent are being displayed rather dark instead.


A few other things noticed:

'supportedLevels' is being set to '3', which forces TV levels, yet MPDN is blending onto PC range range expanded video resulting in faded subtitle output.
[XySubFilter will only perform TV.601->TV.709 matrix correction depending on the script 'YCbCr Matrix' value if the Consumer request TV range output, and the yuvMatrix value is set to TV.709.
For all other scenarios, the consumer is expected to handle these matrix corrections itself when needed.]

'arAdjustedVideoSize' width is being reported incorrectly.
[1920x816 non-anamorphic video in MPDN is reporting 4517x816]

'videoOutputRect' & 'subtitleTargetRect' are always reporting the desktop size instead of the active window/output size.

'frameRate' is being reported incorrectly. On a 23.976 fps video, MPDN seems to be reporting the REFERENCE_TIME equivalent of 41841 fps.
[XySubFilter currently doesn't use the frameRate value for anything, but should probably be fixed anyway.]

'yuvMatrix' is always being reported as 'none' instead of the actual video matrix. The YCbCr->RGB matrix conversion used by MPDN should be reported here.
[LAV Filters reports the actual video matrix bitstream flag (if present)]
[Edit:MPDN 2.10.0 actually does correctly report yuvMatrix, but only after playback start. I mistakenly checked only the initial connection.]

'combineBitmaps' is set to True, which forces XySubFilter to combine all subtitles into a single bitmap per frame.
[While not an issue, performance with 'combineBitmaps = False' which will only combine nearby bitmaps, should generally be more efficient]

Starting v2.3.0, the 32- and 64-bit editions now have their own app config file (stored in %localappdata%\MediaPlayerDotNet).

You can just plug that part in bold into your location bar, and you'll find the config file he's talking about.

found a huge bug with xy subfilter:
video playback just stops with animated subtitle. audio is still running.

sample: "later" need a new file hoster ...

works fine with addblock: http://www.file-upload.net/download-9860859/animated-sample.mkv.html

Shiandow, could you please add an example of how to use your ChromaNEDI into the script, which I'd like to give it a try?

I know you're quite busy with the script stuff, how's the tweak of the SuperRes algorithm recently, any improvement on that you'd like to share with us?

I know you're quite busy with the script stuff, how's the tweak of the SuperRes algorithm recently, any improvement on that you'd like to share with us?

Well, adding the ChromaNEDI shaders in an Image Processing script and setting Chroma upscaling to "nearest" should still work. It would be nicer to create a render script of it, but I'm currently a bit busy with making it easier to create render scripts. I'm also not sure if I would recommend using ChromaNedi, it tends to blur chroma too much. This wouldn't have been that bad if it could work in linear light, but it can't (or at least not without introducing a lot of artefacts). So I likely won't make a render script of it at all.

I've been able to make some improvements to the SuperRes algorithm, although none of them particularly recent. There are some limits to what I could do using only shaders so the current versions are far slower and lower quality than they could be. Anyway, the main improvements are that I can now scale to arbitrary sizes. I've also added some basic anti ringing which makes it possible to increase the strength of the algorithm without increasing ringing. Also, if you'll remember, SuperRes is trying to invert a specific downscaling algorithm and it turns out that if you use a better algorithm then SuperRes also improves quite a bit, especially w.r.t. aliasing. However so far I've only gotten it to work with linear scaling, bilinear just becomes too slow. It should be possible to make this work in a render script. I've also adapted SuperRes into a chroma upscaler, which (unlike NEDI and most other algorithms) is able to work in linear light, this gives some pretty impressive results, although it's not quite fault free yet.

Some of the above such as premultiplied alpha I haven't forgotten about. Just ran out of time so I simply blit the texture to screen without bothering to change my renderstates. The point of the experimental support was to have a version out that people could test and see that something gets rendered on the screen and to find bugs such as what Huhn has encountered.

Other ones are simply just bugs because again I ran out of time. For example I do get the colorimetric info from upstream. It's just the sequence of the settings getting polled that caused it to return none.

But the one about returning desktop resolution as target rect is done on purpose at least for the first few versions. This will change eventually I sort out the show stopping bugs. It's not that critical anyway as the point of XySubFilter is to have high res sub as input texture.

Ok, tested new 2.10 version and the problem with the "Option" panel was gone. Now I'm testing the player with my optimus laptop and it seems the only way to decode the video by the NVIDIA card. Unfortunately, if I try to use the DirectX 10 version the player stucks after few frame, freezing the last image rendered. With DirectX 9 decoding no problem at all (at least so far). I'd glad to help in debugging these issues with Optimus system, but I don't know how...could you help me? :helpful:

If you go into Video Renderer -> General is Use new windowed mode rendering path when possible checked? If so try with it unchecked. On my optimus system it has a problem if I choose Direct3D 10.1 and that checked. If I have that unchecked then there doesn't seem to be any problem.

[Zachs]

found a huge bug with xy subfilter:
video playback just stops with animated subtitle. audio is still running.

sample: "later" need a new file hoster ...

works fine with addblock: http://www.file-upload.net/download-9860859/animated-sample.mkv.html

Of cause this sample works fine in MPC-HC with madVR and EVR CP


Thanks for reporting this huhn!

It turned out to be a simple one to fix - I forgot to check for the HRESULT of XySubFilter's GetBitmap() which in this case failed but I assumed it's a valid bitmap.

Hey many thanks! It works flawlessly!

Sorry, I have to correct myself...after some tries the problem returns; still no problem with DX9 mode :confused:

Does it eventually display an error box after the stall/halt/freeze occurs (like a DX.Sharp error message)? Do you have any renderscript items running? (some of the error messages I've seen correlate and only occur when certain renderscript / shaders are running). If you have renderscripts running (ex: NEDI, resizer, etc) try removing them and test without them. Does the problem still occur? If it only occurs when a certain renderscript (or combination) occurs report what it is and Zachs or Shiandow may be able to figure out why its occurring and provide a fix.

You could try running DebugView (http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx)while running MPDN. If an error occurs while trying to render a frame it's error message is suppressed but you should still be able to see it in DebugView.

Ehi many thanks; with this app, I collect some of the following errors:
[3540] [8765'856,631ms] Frame dropped - 9312,875ms late

Effectively the player freezes the image and restarts after that amount of time approx for each frame. BTW, this only occurs with DirectX10, no problem with DirectX9. I used a 1080p file, below the detailed info:

Oh my, 9 seconds!!! That means the GPU driver is stuck and someone needs to tell NVIDIA!

EDIT: What this means is the driver effectively took over 9 seconds to render a single frame all of a sudden. There's really not much an application could do when the driver misbehaves.

[matthew_eli]

Added info on the file. I have the latest NVIDIA driver installed...WIth DirectX9 I tried also a 4k sample in HEVC and it works perfectly smooth...

[Zachs]

Is there gonna be pan and scan? I like your player so far but can't get along with it without having a way to zoom video :(
thanks

I hope v2.11.1 is what you're looking for - from full letter boxing to none in 25% steps.

[kerimcem]

Added volume control
:thanks:

Since I always seem to get errors (on MPDN launch after extracting RenderScripts) or go into the renderscript configuration area only to find it empty (nothing to select) how about a little more specific clarification for exactly what from the zip needs to be extracted to what directory of MPDN?

In the RenderScript.zip there is a:
RenderScripts-master folder
inside that there is:
RenderScripts folder, src folder, license file, and readme file.

For this example we'll say MPDN is extracted to:
E:\Program Files\MediaPlayerDotNet
According to the instructions on the zip download site, and the readme "Then extract the files and folders in the RenderScripts folder (located in RenderScripts-master folder) to your MPDN's RenderScripts folder."
One would be (after clicking on the zip, and going into the Renderscript-master folder) extracting the RenderScripts folder, src folder, license file, and readme file into the E:\Program Files\MediaPlayerDotNet\RenderScripts folder that already exists there (and should be empty according to the instructions). Thus one would have a seemingly redundant RenderScripts folder inside a RenderScripts. Thus it would look like this: E:\Program Files\MediaPlayerDotNet\RenderScripts\RenderScripts . Is that correct?

Is some of my extraction tests. (Example extracting the RenderScripts directory on top of the MPDN RenderScripts directory (replacing the first, and putting the src and license files in the MPDN directory/folder) I get an error that reads:

TITLE: mscorlib Error

No, you should have only 1 RenderScripts folder. You can ignore the src folder and readme/license files.

In that case I get the

From what I understand it seems that windows doesn't trust the "framework.dll" file and is sandboxing it. You can either open the properties of framework.dll and press Unblock (as in this image (http://blogs.msdn.com/blogfiles/drew/WindowsLiveWriter/xUn.NetFixingtheattemptwasmadetoloadanas_E6EF/Unblock_1.png)) or you can replace framework.dll by the files in the /src/framework folder.

[Zachs]

It looks like we would need to get an open source code signing certificate to sign the dll.
Luckily it is free for open source projects.
I'll take a look into it.

Can you try this for me please?

Open MediaPlayerDotNet.exe.config, and remove all the contents, replacing them with the following.


<?xml version="1.0"?>
<configuration>
<configSections>

Changing the contents of the MediaPlayerDotNet.exe.config file to what you wrote worked to solve the problem. Given Windows 8.1's convoluted file system it wasn't as simple as replacing and saving. (That would give me an access denied message). I had to save the modified file to my user directory, delete the old file, and then copy the new file from my user directory back to the location of the MPDN files (inside E:\Program Files\MediaPlayerDotNet and E:\Program Files (x86)\MediaPlayerDotNet(x86) respectively).

Just to be sure I don't have other things fouled up. The Render system is back to the previous one render at a time instead of being able to stack/chain like in the previous recent versions. For example : I could select NEDI, or Resizer, but it looks like both may not be able to be used at the same time aka stacked/chained.

In other words its back to looking like:

instead of like:

Chaining is still there, under the script called "Script Chain". If you select that and click Configure, you'll find that same interface you were used to in previous versions of MPDN.

That will teach me to examine the screen fully before posting next time...or maybe not...;):thanks:

[edison]

Is that possible provide a mirror full screen mode when using multiscreen.

[Zachs]

Nope. MPDN only works on one screen at a time in full screen mode.

BTW, you can also start your text editor as admin to work around this, then you can write anywhere. The downside is that drag-and-drop stops working.

[Zachs]

I'm going to be naughty and give all of you a little sneak peak of what's to come :)

Custom scalers (Yes, you can add your own scaler)

e.g. Guassian:

var sigma = radius/6;
return Math.Exp(-(x*x/(2*sigma*sigma)));

[foxyshadis]

Can't beat that, it's starting to look really good. Even if the UI is still a bit raw, this is the image-quality fanatic's dream player.

[ryrynz]

Add a few more buttons on the player, give it the ability to change colour, add a ton of keyboard shortcuts for most things MPC-HC does.. and yeah I think I'm sold.. as long as I can get better quality upscaling than NNEDI offers in madVR (haven't checked out any SuperRes comparisons) I'm guessing it's somewhat high (in comparison to MPC) memory footprint on idle is the result of using dot net?

Can't beat that, it's starting to look really good. Even if the UI is still a bit raw, this is the image-quality fanatic's dream player.

Yeah if it continues this path it's going to be hard to pass up. The 64 bit option is great, this player looks to be quite lean on resources when playing too.. wouldn't mind seeing a more detailed comparison vs other players in that area. I just wonder when it's going to stop.. Zach any plans continuing with this as an options vs MPC and MadVR? Or are you just adding a few things here and there for the near future just to give to the community a bit? as you've already created what was required for your own work.

[toniash]

It'll be ready when it's ready.
CAN'T WAIT!!! :cool:

[Shiandow]

as long as I can get better quality upscaling than NNEDI offers in madVR (haven't checked out any SuperRes comparisons)

Better than NNEDI might be difficult, I'm definitely going to try though! So far I've managed to make it sharper but with slightly more aliasing. Hopefully combining it with NEDI will improve this. And maybe someone will port NNEDI3 to MPDN at some point (which could also be combined with SuperRes...).

At any rate using SuperRes for chroma up-scaling beats any other algorithm I've seen purely because it can do part of the processing in linear light. Example: SuperChromaRes (http://i.imgur.com/HbvS1fw.png) vs Bicubic (http://i.imgur.com/mEaO6jh.png). If you are lucky you might achieve similar results with NNEDI3 but I doubt it, the SuperRes algorithm is just better suited for this kind of processing.
