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

[The Dark Lord]

I'm having problem with playing some MKVs mostly those downloaded from Youtube.

MPDN is rendering the video at average of 15 frames, which of course translates to massive stuttering.



as you can see there are no dropped or delayed frames.
MPC-HC and other players like VLC have no problem rendering these files at 23 frames.

My specs:

win 10 64bit
i7- 4770K
Geforce 970 (Driver 361.43)
Latest MPDN 32-bit

Right on this weekend?

With any luck, yes. At any rate it'll be soon.

The code's already on Github, you could also copy that to the Extensions folder and use it that way. At least, I think that should work.

I'm away on holiday at the moment though. Buy I have my laptop with be so hopefully I'll find some time to do a release later today.

did the livestreamer issue i had work for you?

[Zachs]

Haven't had time to try it yet. But have your tried YouTube-dl? Does that work?

i saw it mentioned earlier in the thread when i good livestreamer and mpdn but I had literally no idea how to install it or get it working and it seemed from what i could see, be a way to download videos then watch them later rather than stream them directly through the browser?

but no im somwhat savvy but this was beyond me could you point me the github/mainpage didnt make any sense on how to install/work.

[huhn]

this is how it works: http://forum.doom9.org/showthread.ph...be#post1739563

livestreamer a easier way to start livestreams but check youtube-dl first.

I was kinda expecting something amazing from the new SSIM downscaler but there wasn't that much difference when compared to lanczos 12AR IMO. It looks nice and all and I'd probably use it but it's no night and day difference.

Thanks for the feedback, shame it wasn't as good as you thought it was going to be. Is there anything in particular that you think could be better?

FWIW something like 12 taps Lanczos is already pretty sharp to begin with, so in most case you shouldn't really need much additional sharpness (except if you downscale a lot). That said, in theory SSIM should be somewhat more intelligent, it adds exactly* the right amount of sharpness instead of just a lot of sharpness all the time. It could be sharper when downscaling very fine details, or for higher scaling factors. The SSIM downscaler will also be a bit smoother on less detailed regions, but that might not be particularly useful (although it does suppress source artefacts)*.

*Your mileage may vary.

[Anima123]

SSIM has it's own character for sure, you need to check several times to find the optimized settings working together with e.g., image doublers.

That is why I am more curious than ever, what it can produce with SuperRes or whatever you might call.

Edit: Right now I am using the following render chain, which seems to benefit from SSIM quite a lot, at least from 576p -> 1080p:

It just the content I was using. SSIM's strength is in the details, patterns and white areas. If you don't have this sort of content playing someone might instead prefer to run something else for a sharper picture. The content I was playing was computer generated so what I saw looked similar overall in sharpness to lanczos.

Exactly right. Some might prefer other downscalers with less detailed content. I don't feel it's probably the one downscaler to rule them all but I have no doubt it'll be popular with general content, it's magic is in the finer details.

SSIM

Lanczos 16AR

The broccoli, the quilt patterns and the shreds inside the crayfish are nice areas of improvement over Lanczos 16AR.

It's always helpful to include the original size image.

[Thunderbolt8]

It would also preferable to use an imagehost for the two pics instead of having to go through a download process.

I tried for over an hr last night.. Every image provider either resized them wouldn't accept them or changed the brightness.. Any recommendations?

I'll link the source later. I don't have a 4k screen.

did you try imagebam or someimage?

For some reason I just cannot explain the Lanzcos image gets brighter when uploaded to various image uploading sites.

If someone could tell me why this happens I'd really appreciate it.

Hi,

I wanted to have a look / test SSIM but I got trouble using it for a simple reason: it's not showing in MPDN. When I go to Program Files / MPDN, the folder is in RenderScripts. Though it's not present in App data.

Thank you very much.

[Shiandow]

So you copied the "SSIMdownscaler" folder? Did you also copy the "SSimDownscaler.cs" file? That one should be in the RenderScripts folder as well.

[Zachs]

I've released the binary version yesterday. If you updated the extensions you should automatically have SSIM.
