[WiP] madVR support in MP1 (10 Viewers)

[Freuli]

Hi Sebastiii,

with v430 I had already 2 crashes after starting a mkv with AVR on and DRR. Unfortunately I don't have a log for the first one. I got a madvr crash window. For the second, I have the log attached.

Hey

That's not good does it happen with EVR too ?
Thanks.

Hi, with EVR I had no real crash. With DRR sometimes the behavoiur is quite strange. I can see the Windows desktop flickering and then the video starts. Logs are attached.

regards

Hi
I have maybe an idea, the new option for blackscreen is maybe not enable and then the fix is not handled
Will look at your last log to confirm it

 

[Sebastiii]

Ok the option is enable, so something wrong happen the flickering is the workaround to fix the blackscreen, it's the flickering we can see when the option is ON on HTPC that doesn't need the fix like mine lol.

@Freuli
Can you test all files one by one and tell if one of them works ?

With madVR :
Option FCU ON
Option FCU OFF
DRR ON
DRR OFF

Ofc you can try EVR to see if there is a diff
Thanks.

Good that always the same issue, can it be related to DXVA Native (D3D9 or D3D11) ?

Maybe, I was using the D3D11 hardware decoder in LAV up until I reinstalled the 0.70.02 released version some while back, which does not have it, I then used DXVA Native. Both these decoders will play the 4K/HDR demos that I use in the test suite, with DXVA Copy-back I get only audio with a black screen or extreme video stutter. CP is OK for everything else including the 4K Elysium demo so could try for a crash with it if you want me too.
Let me know if you have something for me to test and how.
UPDATE:-
I gave DXVA-Copy Back a try and quite quickly got a Madvr crash, while playing a vid, it happened when in Windowed mode I double clicked the Madvr icon on the task bar to bring up the settings, coincidence???. I did get the setting menu and the vid continued playing but with the Madvr crash notification on screen, strange. Crash report and logs are attached.

Hi @joecrow

Same crash

Application: MediaPortal.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.NullReferenceException
   at Microsoft.DirectX.Direct3D.Surface.Dispose()
   at Microsoft.DirectX.Direct3D.Surface.Finalize()

So madVR crash windows happen when the above crash is trigger.

Will try a bin for you to see how it goes

@joecrow
Attached is to test

It seems that on togglescreen, the D3D is kind of reset for the backbuffer etc. and after a while, code need to free/dispose memory to something already disposed or something else and then lead to the crash. I think it's related to GC (Garbage collector).

Can you try also to reproduce with EVR ?
Thanks.

@joecrow can you test with Auto3D off too ?
