Cheese, Camera app, and ffplay all show a black screen. The uvcvideo module is loaded, but no video stream is decoded. When I cover the webcam with my finger, the placeholder disappears, so the hardware is functioning. Technical details: - Webcam device: /dev/video0 - Supported formats (from v4l2-ctl --list-formats-ext): MJPG: 1280x720, 640x480, 320x240, etc. YUYV: 640x480, 320x240, etc. - ffplay output shows "EOI missing, emulating" for MJPG and black screen for YUYV. - Attempts made: 1. Reloader uvcvideo with quirks=128 2. Switching kernels (6.14.0-27, 6.14.0-29) 3. Using Cheese and Camera app - Result: Webcam still shows black screen, no video captured.
