Pipe pipewire to ffmpeg stdin

Question

I want to take audio from pipewire and send it to the stdin of ffmpeg via it's use of command line pipes. Is there a way to get audio from pipewire to something like a cat command?

Answer 1

ffmpeg can run as a jack or pulse client, so the way forward is to treat pipewire as it if were one of those two things.
