Opencv 3.4.4 Error

[daskalakisgiorgis]

Hello Everyone.

I am running a code for detection of a aurco marker in C++. It is able to compile properly but when I run the code it comes the following error:(Project: 23857): GStreamer -CRITICAL **: gst_element_get_state: assertion ‘GST_ELEMENT (element)’ failed.
VIDEOIO ERROR: V4L: can’t open camera by index 1.
In addition to it, I tried using index as 0 but still, I am not able to open the camera of Jetson board. But, I checked the camera is working using the camera :nvgstcapture.
I will be grateful for the solution.

Hi,
Onboard camera should use nvarguscamerasrc(or nvcamerasrc). Please refer to

The examples run nvcamerasrc, which is deprecated in r32 release. Please use nvarguscamerasrc instead.
