External webcam not working on Apple Silicon (M4) Mac Mini

Hi everyone,

I’m trying to use an external Logitech webcam (Brio 300) in Processing on a Mac Mini M4 (Apple Silicon).

Processing detects the camera (it appears in the device list), but it fails to actually capture video. I get GStreamer / AVFoundation errors and the stream never starts.

After testing different Processing versions and libraries, it seems there might be a compatibility issue between Processing’s video stack (OpenGL / GStreamer / JOGL) and newer Apple Silicon Macs.

Has anyone managed to reliably use an external USB webcam with Processing on Apple Silicon (M1/M2/M3/M4)?

Is there a known workaround or recommended setup?

Thanks in advance.
