any way to make transparent the black background?

This is a bit of a silly question, but is there any way to make the black background in OBS transparent? I'm not talking about chroma keying. I mainly use OBS for the virtual camera, and when I turn it on and use it, the black background is visible and annoying when using it in other applications. Any solutions?
