privacy block ignores webcam #2007

Closed freswa closed 3 months ago

freswa commented 4 months ago

Expected behavior: The webcam logo is displayed in the privacy block upon webcam usage.

Actual behavior: Webcam is used, but only the microphone logo appears in the privacy block.

Further information:

❯ ls /dev/v4l/by-id 
usb-Chicony_Electronics_Co._Ltd._Integrated_Camera_0001-video-index0  usb-Chicony_Electronics_Co._Ltd._Integrated_Camera_0001-video-index1
[[block]]
block = "privacy"
[[block.driver]]
name = "v4l"
[[block.driver]]
name = "pipewire"
display = "name"

What's the best way to debug this issue?

Can you share the output of ls -lA /dev/v4l/by-id /dev/video*? The next step would be to get the output of ls -lA /proc/$PID_OF_CONSUMER(like firefox)/fd

Looks like in /dev/v4l/by-id: there's nothing pointing to /dev/video0 (unless it just got missed in the copy/paste). I'm going to take a look at just scanning for /dev/video* as mentioned in #2006
