Gstreamer and OV9281 error
Hi,
I have two OV9281 EK0033311 V1.0 from you which I wanted to connect to my Jetson Nano B01 dev board. However when I try to use them with gstreamer it fails. I've tried L4T versions 32.6.1 and 32.7.2.

Have I forgotten some setting?
Hi hobbeshunter, guvcview and nvgstcapture-1.0 are not tested and therefore not supported. Please use gst-launch-1.0 to use gstreamer:
gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM),framerate=20/1' ! autovideosink
I can't see any errors in your device tree file.
Thank you very much. That worked!
Follow up newby question: How do I use this with opencv?
I've tried
import cv2
import sys
gst_str = "nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM),framerate=20/1' ! appsink"
cap = cv2.VideoCapture(gst_str, cv2.CAP_GSTREAMER)
if not cap.isOpened():
print('Failed to open camera!')
sys.exit()
while(True):
_, img = cap.read()
cv2.imshow("cam", img)
key = cv2.waitKey(10)
without luck. OpenCV version is 3.2.0.
Thanks in advance!
Hi @hobbeshunter I am very busy currently. I try to support you from the 14th.
Some more results from experiments:
When I try
gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM),framerate=20/1,format=NV12,width=1280,height=800' ! nvvidconv ! 'video/x-raw, format=GRAY8' ! autovideosink
