Magic Music Visuals

@loncondon Very interesting, so can you choose the dummy HDMI as a source under Display Capture in OBS?

I would like to broadcast my magic visuals, while making them react to the audio in a video. I use OBS a lot but I still haven't found the best way to do that. Or at least, to get the visuals to react to the audio of the video, while the video is playing, ideally as a video source in OBS.
