Razer built-in webcam not working

when I start a video call the green light turns on but the image is black

v4l2-ctl --list-devices:

USB Camera: USB Camera (usb-0000:00:14.0-7): /dev/video0 /dev/video1

after closing video app:

sudo rmmod uvcvideo && sudo modprobe uvcvideo

rmmod: ERROR: Module uvcvideo is in use

how can I get it working?

Please run ffplay /dev/video0, ffplay /dev/video1 and check if you get the same result

/dev/video0: Device or resource busy

Please run fuser /dev/video0. It’ll say something like

/dev/video0:         606564m

now take that number and run readlink /proc/606564/exe, and it’ll tell you the name of the program which has the device open, close it, and then try ffplay again.

closed the app that showed up, green light still on, ffplay /dev/video0 still showing busy

edit: ok force closed app in activity monitor & green light turned off`

ffplay /dev/video0 turns camera on and doesnt give “busy” error but camera app still shows black screen

edit 2: works!
