Concept: Switch MP2 to D3D11/D2D rendering (1 Viewer)

[hofi]

Did a test on Windows 10 technical preview, but there is only a black screen with mouse cursor, if i use the cursor buttons on IRFB i hear the switching between the plugins.
On the Server with Windows 2012 i testet this version also, and there it's okay.

@Developers , mainly @Stéphane Lenclud could you help in D2D debugging? Issue seems to be a D2D effect with two input sources (image 1 + 2 for transition) and a set of parameters. When calling the effect rendering, I get an "INVALID_ARG" then all further calls an "INVALID_STATE".

The render starts here, coming with 2 inputs: https://github.com/MediaPortal/Medi...gement/AssetCore/EffectAssetCore.cs#L195-L197.

The calling code is the ImageContext, StartRenderTransition:
https://github.com/MediaPortal/Medi...kinEngine/Rendering/ImageContext.cs#L218-L243

The ImageTransitionEffect is defined here: https://github.com/MediaPortal/Medi...isuals/Effects2D/ImageTransitionEffect.cs#L67. The attributes on member properties are used for SharpDX parameter mappings to the data structure (is set as "Constant Buffer" to the shader(s)).

I think I already have double checked all types and indexes of variables and also order of constant buffer, but somewhere an issue is hiding It also could be a problem with the later combined shader sub functions for transitions (they are selected randomly).

Still don't have MP2 clone here I'm afraid.

Not sure what gives you "INVALID_ARG" and "INVALID_STATE". Are those DX error codes or SharpDX?
Typically a shader will take a certain set of input arguments (attributes or unifroms), maybe that's your problem.
I would recommend you try implementing your transition effects outside MP.
This SharpDX library your are using surely comes with some examples you could modify to test your transitions?
Did it get broken when porting from one version of DX to another? Are you sure your are using the SharpDX library that works with the newer version of DX?

So far I've noticed two issues, both inside Titanium:
1. when you open the shutdown menu and scroll up and down few times, everything disappears and the home screen looks like in the attached screenshot.
2. when you go into settings, then back and then again into settings, the settings menu will have now buttons and not list items (screenshot). Selecting on of the buttons crashes MP2

Besides screenshots, I also post logs from both "sessions".

Also found this.

Thanks! Both things are normal: this is a "Debug" build where more test plugins are enabled and they don't have own tile images.

ALT-Enter causes screen to go Black. Had to use ALT-Tab to bring MP2 Client Screen back.

This is indeed an issue...

Thanks!

Seems to be a new issue, effects doesn't work the same way in Win10. The failing function is a D2D1 internal one. So for now I would not spend too much time in debugging Win10 issues until the product goes RTM.

The error codes are from DX11.1: E_INVALIDARG and E_INVALIDSTATE (for all subsequent calls after the first error appeared). SharpDX is "only" a C# wrapper around DX and D2D APIs.
Unfortunately there doesn't exist many examples for custom D2D effects, which I use here, especially with 2 inputs. The normal single image render effect is quite similar and is working correctly (after many days of work )

Did it get broken when porting from one version of DX to another? Are you sure your are using the SharpDX library that works with the newer version of DX?

Yes, didn't work yet since the D2D rewrite of those classes. In DX9 version everything is fine. Main issue is that D2D is also another API on top of DX11.1 for 2D drawing operations. This is good for all GUI rendering, but introduces new problems in shader handling: i.e. I cannot control SamplerStates to use other modes than "Clamp" (I need "Border" for all of our uses)

Thanks! There was an internal driver error which caused a "device lost" and re-creation of device:

The error code is:

The driver encountered a problem and was put into the device removed state.​

A driver update could help maybe...

But an issue remains: after device reset the textures should be re-allocated which doesn't seem to happen

Hi,
i have noticed the following in the menu section:

After mouse movement:


logs added

 

[morpheus_xx]

I also have issues with dialogs on my tablet. A driver update to the inbuilt Intel HD graphics is not available. So I hope we can fix this in code. If not we might need a way to disable effects in such cases

 

[Stéphane Lenclud]

So DX9 version did not use D2D. Would it be easier to first just move to DX11 and then consider a move to D2D?
Maybe you are trying to hammer in 3D stuff into your 2D framework and it does not like that. There should be nothing the 3D framework cannot do in 2D. It's just a specific projection.
