changing "play" launching program

How to change the launching program when I click on [PLAY]

Thanks.

That option launches the default video player on your system. I’d have to know what is the OS you’re using to help you further.

Options–>Advanced–>ui.preview_program_path

That needs to go into the FAQ.

Thank you.
