qr reader gets stuck in dark - linux mint user

[craigraw]

Please provide more information.

What version of Sparrow? What camera hardware? What operating system version?

[matiasnietopastor-jpg]

Latest version of sparrow. Camera works fine on cheese for instance.
But qr reader works fine if a log in on debian or whonix terminal on same laptop but not on mint... So I believe must be a problem opening sparrow on mint....

[craigraw]

I still don't know what version of Linux Mint you are using. But it seems likely it is exposing an incompatible MJPG stream.

You can try the following to see if you can get another video format:

sudo modprobe -r uvcvideo
sudo modprobe uvcvideo quirks=128

The above is just temporary and will be reset on reboot.

Linux Mint 22.1 Xia

It did not work your option...
