when I start a video call the green light turns on but the image is black
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?
ffplay /dev/video1 and check if you get the same result
/dev/video0: Device or resource busy
fuser /dev/video0. It’ll say something like
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
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!
