Error opening video capture device: /dev/video0 inside docker container

[dipshirajput]

Hi all, I am building a docker container for usb image/video capture. while doing so, I am facing the following error,

Error opening video capture device: /dev/video0

even though the container has access to /dev/video0 but is failing to open video capture port.

please let me know for any suggestions. Thanks in advance.
