Good morning.
I have the issue posted at https://obsproject.com/forum/threads/vlc-video-has-black-screen.128307/ .
But this time isn't the vlc the program, the program is something like an vlc library base OR vlc base program. The program don't allow me to show as windows gdi video output or even change this aspect. I think the program is vlc java library based.
The display capture option from obs works fine but the problem is that i cant use it because im trying to use obs as a projection software to capture the window of the main projection software(the window with this problem) and mix it with videofeed from an videocall. One scene with only the main projection software and another scene with the main projection software and the videocamera feed.
Is possible to install another windows capture methods on obs.

The only thing that works fine for yet is in the program that i want to capture the Theme option JavaFx instead of VLC. I prefer the tjhe second one because is lightest.
 
Check the correct way in correctp.png with JavaFx and the uncorrect in other file. In the uncorrect appear some black windows too. See on preview side
