oCam-1cgn-u returning empty frames #21

Hi,

I'm using ocam-1cgn-u and running the guvcview version 2.0.5 on Ubuntu 18 to make sure that the camera works perfectly fine and every once in a while it returns empty frame. I noticed this using pupils lab uvc backend and wanted to test this independently to confirm. Could you please help me with this?
Thanks
