You can parse the output of following command

gst-launch-1.0 v4l2src ! fakesink -v | grep fake

Hi Baby Octopus,
Thank for your reply, but that command does not give back the accuracy information about input video stream and it make my hardware stop working.
Do you have other suggestion?
Thank.

You want the output of

  gst-device-monitor-1.0 Source/Video
