title: Unable to access camera in Docker container of Ubuntu
body: <p>I am writing a simple code of Opencv which captures images and show us. But whenever i am running it it is telling unable to access camera with this index.</p>
  <p>I tried running my docker file with this command
  docker run -ti --device /dev/video0:/dev/video0 pradyumn10/ubuntu-python3 /bin/bash
  This opens camera for a second and then it closes it and gives a error &quot;unable to display&quot;</p>
