Question / Help Game Capture - Blank Preview / Blank Stream

[diznanl]

Hello All,

I am a new user to OBS Studio, but thought I had a few good Game Capture streams setup on Twitch. After restarting my computer, I am getting a blank / black preview and blank / black streams on Twitch... without changing any settings.

I thought it might be onboard video adapter, but that has been disabled in BIOS. I CAN, however, do a Display Capture and it shows fine in preview. However, all Game Captures do not.

I have a theory that it might have something to do with the red outline that allows you to resize your preview and broadcast in the preview window... however, that doesn't even show up for Game Capture.

Here's a video of my desktop showing my settings:

Of course, my mic was up, so please see the settings I show on screen.

Any help is appreciated.

Thanks,
diznanl

*EDIT*

Experiencing the same blank / black preview and stream using OBS Classic.

bump? Any ideas?

I disabled ShadowPlay, which I saw in some other thread ... but I'm getting this error:
16:35:50: Using graphics capture
16:35:50: Trying to hook process: witcher3.exe
16:35:51: SharedTexCapture hooked
16:35:51: Capture window 0x000609B4 invalid or changing, terminating capture

I was able to stream using the Window Capture feature rather than Game Capture. Not sure why. It worked exceedingly well... no lag, very low artifacting and compression.

If anyone knows of any outstanding bugs with the Game Capture mode, please let me know.

Thanks,
