Thanks, that wasn't at all obvious... I had to figure out also how to get audio to redirect in Pipewire, but now I can actually see the output.

I suppose this thing would probably be more useful as an ffmpeg filter and/or audiacious plugin.

This is a fantastic idea! I forked [1] projectM a while back to work on a few modifications such as screen and audio recording (by saving raw framebuffers) and being able to select the active preset remotely from a web interface so I became somewhat familiar with the way projectm handles A/V input/output.

I just took a look at ffmpeg’s video filter interface and it looks like linking the two could be doable!

This feels like a much more elegant solution for recording frame-perfect captures so thank you!

I’ll definitely be looking more into it.

IMO making a projectM-gstreamer plugin would accomplish this a lot easier and better. I wanted to do this but wasn't sure how to create the GL context. Started it a while back: https://github.com/projectM-visualizer/projectm/pull/207
