Why does HyperHDR use my webcam?

[JoshAtticus]

Current;y covering my camera in masking tape right now, only installed HyperHDR and boom, the camera led turned on. ran sudo lsof /dev/video0 and confirmed it is using it

josh@Josh-Alt-Laptop:~$ sudo lsof /dev/video0
[sudo] password for josh:

hyperhdr 3951 josh mem CHR 81,0 569 /dev/video0
hyperhdr 3951 josh 17u CHR 81,0 0t0 569 /dev/video0

Please tell me why this is happening.

sudo killall hyperhdr makes the camera LED turn off.

Just disable grabber (camera is auto-detected as a video device at /dev/video0, same as grabbers) in the video control: same page where you have the grabber configuration. Or manually select your video grabber from the list if you have one.

not an issue, moving to the discussion
