Hello,

 

I upgraded our lab Trio 8800 + colaborative kit using the logitech webcam C930 in the last UC version (5.5.3). Since that, the camera is catching the image in black and white (on the local screen and also on remote equipment during a call). 

When we unplug and replug the camera, the image is in colour and come back to balck and white after some seconds. So the webcam is not faulty for me.

In the logs of the visual + I found this error message:

 

0105135343|mrcam|4|00|soMrUVC::getControls: IOCTL error: device=/dev/video0 fd=238 cid=0x980910(V4L2_CID_GAMMA) value=0 errno=22

 

Any ideas of waht could be the issue?

 

Thanks for assistance

Hello all,

As already stated this is with Polycom support and as a workaround please do the following:

 

  • Settings->Basic->Video->Camera Settings->Camera Preferences and click the "Reset" button located at the bottom of the page
