RE: Windows DirectX 11 upgrade test thread - fritsch - 2015-06-21

Guys, this is a testing thread at the end and not a "leech whatever you can" thread. Afedchin is working on those issue and fixes will come when they are ready ...

There are a lot of people who use Kodi with single display and your desired behavior will cause a lot of pain to them. Kodi will work as currently. There will be no specific code for dual displays.

i left my test rig playing videos for couple of days. Just checked and it stopped working.
Could be that's an older build but who knows the dumps may be still of some use

Will take a look.

Sure do it asap.

You're right, I didn't think of single screen users, my bad. I will wait until your branch is merged and then PR a better solution.


RE: Windows DirectX 11 upgrade test thread - afedchin - 2015-06-21

If you can provide a better solution, it's a good time. We all can test it before dx11 will be merged.

Try new one from here screensaver.shadertoy


RE: Windows DirectX 11 upgrade test thread - Martijn - 2015-06-22

updated build listed in first post of this thread. It's a rebased version against normal Kodi master branch.


RE: Windows DirectX 11 upgrade test thread - afedchin - 2015-06-22

thank you @Martijn. I've update change log in the OP.

I've just tried with shadertoy 1.0.2 and the June 21 build however the issue is still present. I've included a screenshot to show the pixelation, you'll need to view the image at full resolution in order to see it.

RE: Windows DirectX 11 upgrade test thread - Memphiz - 2015-06-22

Lack of float precision can lead to pixelisation with the shadertoy stuff - thats what i have learned when playing with it on mali GPUs (which have a really poor float precision). Not sure if this is related here - just wanted to throw it in. For mor information see:

RE: Windows DirectX 11 upgrade test thread - afedchin - 2015-06-22

@tungmeister, Memphiz is right. The "quality" of shadertoy screensaver/visualization depends on float precision. In DX11 float precision depends on your hardware and drivers. I also want to say that nothing has changed in this regard.


RE: Windows DirectX 11 upgrade test thread - Martijn - 2015-06-22

@afedchin
magically the crashing on that one video file has resolved itself with the new build


RE: Windows DirectX 11 upgrade test thread - hewimeddel - 2015-06-22

I know this is not the right thread for requests, but I don't know where else to ask:
With this rewrite will it be possible to use SVP easier or even run Motion Interpolation natively in KODI ?

This would really be great. Me and several of my friends love the Motion Interpolation of SVP and it is a PITA to get it to work with KODI .

RE: Windows DirectX 11 upgrade test thread - afedchin - 2015-06-22

It's not possible, SVP requires DirectShow filter which is not used in Kodi. But in the future when vendors implements the frame rate conversion feature in their drivers then it can be possible natively with dx11/12.


RE: Windows DirectX 11 upgrade test thread - hewimeddel - 2015-06-22

Thanks for your swift reply.
So AMDs "fluid motion video" is supported? Thats great news, looking forward to trying this out.

RE: Windows DirectX 11 upgrade test thread - afedchin - 2015-06-22

I mean when vendors implements support in their drivers for DX11/12 API and not specific vendor features.
