You can use the simple gst-launch example above to determine the camera modes that are reported by the sensor you are using. As an example the same camera from below may report differently on a Jetson Nano B01: -You should adjust accordingly, ie for 3264x2464 @ 21 fps on sensor_id 1 of a Jetson Nano B01: +GST_ARGUS: 3264 x 2464 FR = 21.000000 fps Duration = 47619048 ; Analog Gain range min 1.000000, max 10.625000; Exposure Range min 13000, max 683709000 + +You should adjust accordingly.

If you experience issues, check to see if your display width and height is the same ratio as the camera frame size selected (In the above example, 816x616 is 1/4 the size of 3264x2464). ``` There are several examples:
