unable to open camera

Hi Amirhossein I've decided to use your code on my costume trained weights so i changed classes names and weights file but I'm facing an error

Hi there,
It seems that your problem comes from GStreamer, so I recommend discussing this issue with the main repository, CSI-Camera
But I think reinstalling GStreamer might solve the problem.
