Hi,
I have a code running on Raspberry Pi device. I want to run this code NVIDIA-Jetson. The camera method I use;

def gstreamer_pipeline(
    capture_width=1280,
    capture_height=720,
    display_width=320,
    display_height=240,
    framerate=32,
    flip_method=0,
):
    return (
        "nvarguscamerasrc ! "
        "video/x-raw(memory:NVMM), "
        "width=(int)%d, height=(int)%d, "
        "format=(string)NV12, framerate=(fraction)%d/1 ! "
        "nvvidconv flip-method=%d ! "
        "video/x-raw, width=(int)%d, height=(int)%d, format=(string)BGRx ! "
        "videoconvert ! "
        "video/x-raw, format=(string)BGR ! appsink"
        % (
            capture_width,
            capture_height,
            framerate,
            flip_method,
            display_width,
            display_height,
        )
    )
    cap = cv2.VideoCapture(gstreamer_pipeline(flip_method=0), cv2.CAP_GSTREAMER)

But on the this line for frame in cap.capture_continuous
I am getting the error i mentioned in the title. What can i use instead of this code in NVIDIA Jetson?
Working on raspberry pi code;

camera  = PiCamera()
camera.resolution = (320,240)
camera.framerate = 32
rawCapture = PiRGBArray(camera,size=(320,240))
...
for frame in camera.capture_continuous(rawCapture,format="bgr",use_video_port=True):
frame = frame.array
frame_img = np.copy(frame)
...

Does nvgstcapture-1.0 can see the preview?

I could not understand what you mean.

Just run the nvgstcapture-1.0 from the console to confirm the camera driver is working well first.

6

camera is working

Can you convert below to gst-launch-1.0 pipeline to confirm it can working well.
