OpenCV ops blocking for multi-camera capture with Gstreamer

[DaneLLL]

Hi,
Could you please make a sample based on this:

[Gstreamer] nvvidconv, BGR as INPUT

Hi, We have tried the following python code on TX2/r32.1/OpenCV3.4.1 import sys import cv2 def read_cam(): cap = cv2.VideoCapture("nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080,format=(string)NV12, framerate=(fraction)30/1 ! nvvidconv ! video/x-raw, format=(string)I420 ! appsink") if cap.isOpened(): cv2.namedWindow("demo", cv2.WINDOW_AUTOSIZE) while True: ret_val, img = cap.read(); img2 = cv2.cvtColor(img, cv2.CO…

So that we can run to reproduce the issue and do investigation.
