Win10 falls creators update problems watching videos (3 Viewers)

That's a good news
This part of code will go in the next 1.19 Final

Can confirm startup with no black screen with v422. On startup you see MP-GUI, then for a short flicker the desktop, then again MP- GUI. Unfortunately the other blackscreen issue is unchanged. I have framerate 50p and DRR, if I play a video with 23 p, screen gets black, sound plays. I can refresh monitor by pressing volume up or down or Windows button or CTRL+Esc. If I stop video again, screen goes black again. Here logs

Hi @Chisum

In your log we can see, the GPU is removed when DRR kick-in :

[2018-01-07 14:11:35,843] [Log    ] [MPMain   ] [DEBUG] - Main: Device type is DBT_DEVTYP_DEVICEINTERFACE - Name: Intel(R) HD Graphics 4600
[2018-01-07 14:11:35,847] [Log    ] [MPMain   ] [INFO ] - Main: Video Device or Screen Intel(R) HD Graphics 4600 removed

But come back only after the video stop :

[2018-01-07 14:11:53,537] [Log    ] [MPMain   ] [DEBUG] - Main: WM_DEVICECHANGE (Event: DBT_DEVICEARRIVAL)
[2018-01-07 14:11:53,541] [Log    ] [MPMain   ] [DEBUG] - Main: Device type is DBT_DEVTYP_DEVICEINTERFACE - Name: Intel(R) HD Graphics 4600
[2018-01-07 14:11:53,545] [Log    ] [MPMain   ] [INFO ] - Main: Video Device or Screen Intel(R) HD Graphics 4600 connected
[2018-01-07 14:11:53,549] [Log    ] [MPMain   ] [DEBUG] - GraphicContext: device video connected - Count 2

And somehow, the workaround code to make display the MP GUI isn't trigger, so i need to think about it

Hey
I'm uploading a V424 version in madVR thread, if you can give a try

 

[Chisum]

Tried v424 and looks good, DRR video and wakeup with no blackscreen. Hope logs will help. Thank you, Sebastii, for your patient work.

 

[Sebastiii]

Thanks a really good news

@Sebastiii what exactly caused the black screen, a "device lost"? Could you point me to the related commit that fixes it? I like to check if this is something that could affect MP2 as well.

 

[Sebastiii]

Hi @morpheus_xx
Look at this commit, it's 100% ok for now but better, nope there is no deviceLost, i'm not sure what is the real issue except that when DRR kick in Intel stuff (audio and video are removed added but without creating a deviceLost)

So : MP1-4781V11 : madVR V424 (Blackscreen rework when using DRR) · MediaPortal/MediaPortal-1@f72d13f · GitHub

The workaround is to reduce and restore MP Form from the method : ForceMpAlive();
And not sure really why but part of code line 1545 is needed : GUIGraphicsContext.DX9Device?.Present();

So both are needed and should be executed when device is removed / added

Hi Sebastiii
I've just installed "304128_MediaPortalSetup_1.18.100_madVR_V425.zip" and the blackscreen issue is resolved now. Thanks a lot.
But now, I there is no sound watching some videos...
Here the logs

I did same update, and sound to DTS + DTS HD is gone after this patch/update. Dolby Digital works
