Thank you very much, it solved my problem. Use display capture instead of window capture worked for me.You MUST use display capture to capture powerpoint.
I was having somewhat of a similar issue, screen was just going white. I saw the solution in a video on YouTube. Basically, as long as the PPT slide show is in full screen mode, OBS does not seem to be picking it. Follow these steps, it worked for me
1. In MS Power Point, go to Setup SlideShow
2. COnfigure it to show the slideshow as a window (in MS Office 2016, the option reads as "Browsed by an individual")
3. Now start slideshow. The Slideshow is now in a smaller window which OBS seems to capture automatically.
4. You can now resize the PPT slide show in OBS to meet your needs.
Hope this helps
I think the software works pretty perfectly without workarounds. Set up powerpoint as harisrinivasan suggests:
Then if you go file > settings and go to the hotkeys you can assign hotkeys to starting/stopping recording, pausing/unpausing recording and switching between scenes (among other things). Choose hotkeys that don't interfere with powerpoint itself. When you're recording and have the powerpoint window live, your hotkeys are still read by OBS. So the way I have it set up at the moment, I have OBS on the one half of my screen, the powerpoint presentation window in one quarter of the screen. While I'm going through the powerpoint, I can see what OBS is doing and can see what I'm actually recording.
