The plugin displays a single application for several outputs

[ogmkp]

Describe the bug
If there are several outputs on a program, the plugin displays only one program name.

Screenshots or video
In practice, I tested on OBS with 3 outputs (preview, program and a projector).
The plugin menu only displays one program, "obs", and I have to switch between "capture any window except obs" and "obs" to get the right capture randomly.
For example, to get the projector, I have to switch a dozen times because it will display the preview, the program or the projector randomly.

System (please complete the following information):

• OS: Linux Debian 12
• GPU: AMD R9 380
• Mesa version: 22.3.6
• obs-vkcapture version: build from master today, (CMakeLists say 1.4.4)

Thanks for this project !

Yes, multiple windows from one application aren't really supported. Games usually only have one window.

What exactly is your usecase?

[ogmkp]

I'm using a second OBS as a playout and I wanted to get away from using the less efficient xcomposite window capture.

@nowrep I am having the same issue with Godot.

When I run Godot as:

env OBS_VKCAPTURE=1 godot

Then I run my game from Godot. I got two "godot" entries for it, and it is not possible to select the game output

My use case is to record games in progress for the dev log/streams or to share.
