[WiP] madVR support in MP1 (56 Viewers)

[Sebastiii]

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 ?

Hi,
V1
FCU on DRR on. mkv started but screen stayed black. After a while it jumped back to where I can start the mkv. Second start ob the mkv led to crash.
FCU off DRR on. Worked perfectly.
FCU on DRR off. Worked perfectly

V2
FCU on DRR on. Crash on start mkv
FCU off DRR on. mkv started ok, but by stopping MP crashed
FCU on DRR off. Worked perfectly

Seb I think my main problem was with the latest NVIDIA. I have gone back a version and have yet to see any issues at all (touch wood) even with v430 (either checkbox option). Sorry if I sent your efforts in the wrong direction!

I'll continue to monitor and update when you make new versions as regression testing

v3
FCU on DRR on AVR off. I try to start the video, but the screen stayed black. It was weird, because the madvr information looked like the video was running. MP crashed completly and I had to shot it up.
FCU on DRR on and also AVR on. First start of the video failed. The GUI jumped back to where I can start the video, but no crash. After that, the starts of the mkv ran smoothly.
FCU off DRR on AVR off. worked perfectly

v4
DRR on FCU on AVR on. failed

From the results, I hope I have choosen the right tests. In case of needing any additional, give me a hint.
Testing all is to boring ;-)

I think, the best was v3. Only first start failed and without AVR it's not running.

by the way. Using EVR with FCU on and MP DRR on is working perfectly.

Hi Sebastiii
I have tried the new core and had a Madvr crash both with Auto3D on and off. With EVR I had a single incident where the video froze, with audio still playing and on manual stop audio stopped but then no more control and I had to use the task manager to close MP. After restarting I have not yet had any further problems with EVR despite a long period of heavy usage. Logs and crash reports attached, names say all.
