Media Player .NET (MPDN) - D3D HQ GPU Video Renderer [v2.49.0/v1.31.0 27 Sep 2017]

Hi everyone,

MPDN is a modern extensible media player written in .NET (with performance critical parts in ASM/SSE2) featuring a fully integrated high quality Direct3D 9, 10, 11 video renderer that is equally extensible. In fact, its most powerful features come from its open source community contributed extensions called MPDN Extensions hosted on GitHub. Both madVR and MPV use portions of code from MPDN Extensions.

MPDN Extensions
MPDN Extensions consist of Custom Linear Scalers, Render Scripts, Audio Scripts and Player Extensions.
For more information, see MPDN Extensions wiki page.

Custom Linear Scalers
These custom linear scalers extend MPDN by adding Sinc-Blackman, Gaussian etc. scaling options. If there's a new scaler you want to add, give it a kernel function and MPDN will do the rest. The same custom scalers can also be used in the EWA scaler (via Render Script).

Render Scripts
Render Scripts are quite similar to AviSynth scripts and plugins except they run fully on the GPU. You can script Render Scripts in a similar fashion to AviSynth with a C# syntax, or an AviSynth-like syntax with the full power of JavaScript behind it. As opposed to madVR's mostly closed source nature, MPDN's Render Scripts are fully open source and are hosted on GitHub.
  • Can be used to add post processing pixel shader files;
  • or write your own custom multi-staged scaler
  • or anything in between
  • Supports compiled assemblies (.dll) or plain C# text file (.cs)
  • Easily configured to behave like legacy pre-/post-processing filters (chain of legacy pixel shaders)
  • Or write your own chain script - if Downscaling, use X scaler, if Upscaling, use Y scaler, with or without linear light etc.
  • Or stack image doublers based on your own set of criteria
  • Choose from a combination of Shader Model 3.0 (Direct3D 9), Shader Model 4.x/5.0, DirectCompute (Direct3D 11) and OpenCL!

Audio Scripts
Audio Scripts are similar in concept to Render Scripts except they operate on audio samples. Audio Scripts can run purely on the CPU, interface with third party audio libraries or with OpenCL via Cudafy. See this 2x Audio Gain example.
  • Reclock
  • Dynamic Range Compressor (Night Mode)

Player Extensions
Player Extensions allows the player to be extended via C# script. In fact MPDN's playlist is fully implemented via this extension.
See this post for a getting started example.
  • Modify or extend MPDN
  • Supports compiled assemblies (.dll) or plain C# text file (.cs)
  • A huge collection of extensions on GitHub
  • e.g.
    • Online streaming, pipe input, RAR archives, DVD playback
    • OpenSubtitles
    • Audio / subtitle offset
    • Full screen display selector
    • Refresh rate changer
    • Playlist
    • Remote control
    • and many more

first of all it is work totally fine. it is missing a lot of totally basic stuff like subtitle support, audio volume.

why did you start with 4 taps not 3? 4 is usually way to sharp in my eyes.
I haven't done any picture quality comparison but does it use high bit deep and/or dither?

does it really use the GPU? gpu-z doesn't show anything

Yes it's very basic for now. The player is basically my test app for the renderer. Renderer has text overlay support but I haven't got around to implementing subtitle in the player.

I don't know what madvr's 3 tap really is. But in my renderer 4 taps means it takes 4x4 texels to calculate the resulting scaled pixel.

GPUs calculate in 32 bit floats by default and that's what my renderer uses. What exactly does high bit depth and dithering do? Dithering I assume is to do with conversion from yuv to rgb?

Are u using an amd card? On my amd card Gpu-z seems to show no gpu usage until a certain threshold. But yes it's definitely using gpu for scaling and yuv to grb conversion. I don't think the cpu is near enough for 60fps full screen 1080p jinc

4x4 is two taps (ie 2 pixels in each direction), or also called bicubic.

Isn't 4x4 4 pixels in each direction? My bicubic is from 16 texsamples. I've seen implementations calling this 4 taps.

If you go from a center point (ie. your target pixel), its 2 pixels to each edge, for a full grid of 4x4

The naming of these things is kinda inconsistent among different tools, but madVRs 3/4-tap filters function like I outlined here, bicubic is basically 2-tap, and the other filters with 3/4 tap configuration use more pixels.

Ah ic. I think of all the implementations I've seen and I've seen a lot while making mine, madvr would've been the only odd one out on this.

EDIT: MPDN's 'tap' counting is based on AviSynth's as documented here: http://avisynth.nl/index.php/Lanczos_lobs/taps

Does anyone know where I could find a sample mkv/mp4 with multi-track audio for testing purposes?

*Edit: Nevermind. I found a sample and I've released v1.1.

You may want to sign your exe file to avoid AV false alarms. Virustotal reports 2/54 for your x86 download. Usually signing your exe helps with this problem.

FWIW, on my development PC (win8.1 x64) playback with your software doesn't seem to work. I'm getting the exception "An unexpected error 'System.Reflection.TargetInvocationException' has occurred". Also, I have to use the "File -> Open" dialog. Drag&Drop is rejected by the media player.

How to count taps? Different people have different opinions on that. What madVR calls 2 taps, and you call 4 taps, some marketing guys even call 16 taps (4x4 = 16). In the end it doesn't matter much, I guess. On a side note, personally I find Lanczos, Spline and Jinc with 2 taps (in your case 4 taps) to be not worth the effort. They don't look better than Bicubic to my eyes. That's why madVR starts at 3 taps with those algorithms (which you count as 6 taps).

If you want to know what dithering is for, try playing the "colors.ytp" test pattern with madVR with dithering turned off vs. on. Then try playing it with your media player. If you don't do dithering, it will probably look quite ugly. Or alternatively try zooming the "smallramp.ytp" pattern up to fullscreen, then turn dithering off vs. on. With dithering off, you should see faint vertical bands in madVR. With dithering on, the gray ramp should be perfectly smooth. The problem is that your final rendering result should be 32bit, while the GPU really only outputs 8bit. If you round to 8bit, you're introducing quantization artifacts. So you *have* to dither, to avoid those artifacts. This is a concept well known from the audio processing world. I've introduced this concept to the HTPC video processing world a couple of years ago, when madVR was introduced. At that time (to my best knowledge) nobody else used dithering in video processing. Dithering is well known when trying to convert gray scale images to black & white. E.g. see here:

http://en.wikipedia.org/wiki/Dither

Basically converting gray scale -> black & white means reducing bitdepth from 8bit to 1bit. When doing that, using dithering produces much better results than simple rounding. The same principle still applies when reducing the bitdepth from 32bit to 8bit, although the benefits of dithering are much smaller there compared to 8bit -> 1bit. Here's the download of the "colors.ytp" test pattern with the DirectShow filter needed for that test pattern:

Just found some time to test some low res video clips. I find the above to be false - 4-tap (eq madVR 2 taps) Lanczos, Spline and Jinc look quite different to Bicubic as well as to one another. Try blackberry.mp4 (compare the BlackBerry text) on this page - http://download.wavetlan.com/SVV/Med...P/http-mp4.htm.

You'll find that Jinc gives the best interpolation. In fact, I can't see the difference between 4 or 6 or 8 taps but I can immediately notice the difference going from Bicubic to 4-tap Jinc. Looking at the pictures side by side visually, I can't tell the difference (subjectively) between madVR's 3-tap (which is my 6 taps) to my 4 taps either.

Can you give v2.4.2 a test to see if downscaler bug is completely fixed?

Sorry to disappoint but performance critical parts are actually in ASM and C / C++. C# merely provides the glue logic and it isn't very good at that too with GC stopping all managed threads when it feels like it (which means all MPDN's time critical threads are also in C++).

I can only share it as closed source or don't share it at all (for reasons I can't disclose). If you want to learn about writing a video renderer, there are plenty of resources on the net to get you started.

looks like the general bug is fixed.

but there are other issue.

lanczos creates very strange artefacts when used as downscaler and it is at least half an pixel off to the bottom right compared to spline 4 ar. spline as less deforming aliasing and it sharper at the same time. laczos even creates double lines.

here 2 screens:

spline 4 ar : http://abload.de/img/downsplinewvaq4.png
laczos 4 ar : http://abload.de/img/downlaczosn2l61.png

i added madVR 3 tab ar spline/laczos to show that the difference is very minimal compared to MPDN between them.

i'm currently using windows 10 preview so this can be an windows 10 issue.

on a 120 hz screen playback of 23p is very choppy and juddering a lot more than 23p on a 60 hz screen. madVr works fine with and without smoothmotion.

Found the problem. Affects both Lanczos and Jinc. Fixed in next release. Looks like Jinc is actually quite a good downscaler - it has anti-aliasing features like softcubic but more faithfully retains original color.

You'll also notice that MPDN's downscalers are much faster than madVR, only sacrificing a little bit of image quality. With madVR, I couldn't play 4k downscaled to 1080p on my system with 560GTX but MPDN works without a fuss.

Also found the problem with choppy playback but to confirm, can you switch to D3D10 rendering path to see if it happens there too?

On my system, the choppy playback only happens in D3D9. That was the result of increasing backbuffer count (why this would cause choppy playback, I don't know). A few versions back would have been ok too.

With or without anti-ringing? Or both? I wonder if your algorithm does the same work that madVR does? Maybe you're not reading in enough source pixels? FWIW, are you calculating the weights in real time? Or are you reading them from a texture? I'm reading them from a texture. I sometimes do wonder whether calculating them in real time would be faster. But it will probably differ, depending on GPU generation (and on the scaling algorithm). Older generations have less shader power than newer generations. So probably reading the weights from a pre-calculated texture is faster on older generation GPUs and using real time calculation could be faster on newer generation GPUs.

it's broken with directx 10.1 too but it's fine in full screen mode.

so with a UHD source on a FHD screen madVR does.

chroma upscales FHD to UHD (2 channels to UHD) chroma position correction and RGB conversation and now scaling the hole UHD RGB frame (3 channel) down to FHD.


MPDN has a option for chroma up and down so I guess it's not working like madVR that creates always 48 bit RGB first.

by just scaling the luma channel (1 channel) to 1080p, correct chroma position and by doing a RGB conversation in just 1080p it has to be a lot faster or not?

not sure about the quality through.

Is dxva2n support missing or did I set things up wrong? Using this with LAV filter (testing right now), Video decoder says "DXVA2 (native)" is "Available". (DX 10.1, Win 8.1, NV 660).
EDIT: Just found my answer - "MPDN isn't written with using DXVA at any stage in mind", well that is a performance bummer.

Anyway, some suggestions,
Going to "File" then "Open" brings up a dialog which then brings up a Windows dialog.
After choosing a file in the Windows dialog, the MPDN dialog remains and you have to close it.
Four clicks.
Suggestion, "Open" should bring up Windows dialog directly then when I choose a file in the Windows dialog, it should start playing the file.
Two clicks.

Ease of setup,
Can you include subtitle renderer as part of MPDN (I fathom this is a legal question)? Requiring separate download and install is a negative in my opinion.

Options,
Some questions that the options menu can answer:
(1) "What is faster?" (2) "What this does?" (3) "What is this options recommended for?"

Oh yeah, C++ is too complicated (for me) compared to unsafe C# code. Also, have you tried native .net native? I hope you'll reconsider; it would be a major bummer if development stopped and no one could take over.

it's not rare that DXVA uses more power than normal software decoding making it pretty useless for normal content like a BD on system with a dedicated GPU.

and this is closed software. for a reason the creator knows but didn't want to tell us.

@Hera

Quick Open File menu added in v2.6.1.

A setup package will be used some time in the future when I get some time to do it.

If someone wants to do a write up for the options, I'd be happy to assist and post the link on the OP but I don't want to clutter the options page further.

.NET native won't make a difference to MPDN's performance (GC will still be present and like I said before, performance critical parts are in ASM). And you do know it's not available for desktop apps yet, don't you?

That's just fine with me. If I may ask: What purpose are you writing a video renderer for? If you can't say, for whatever reason, that's ok. Just curious...

Ah thanks for the stack trace!

I wasn't checking for media files without audio in one of my methods. Will be fixed in next release.

As for the actual use, I needed a relatively high quality 64-bit (because the host app which I can't say what it is deals with a huge amount of data) video player with support for custom text/bitmap overlays (event driven).
