1. Python3 读取本地摄像头流

import cv2

if __name__ == "__main__":
    cap = cv2.VideoCapture(0)
    while 1 > 0:
        ret, frameNow = cap.read()
        if ret:
            cv2.resize(frameNow, (0, 0), fx=0.5, fy=0.5)
            img = cv2.resize(frameNow, dsize=(400, 400))
            cv2.imshow("CAMERA", img)
            if ord('q') == cv2.waitKey(10):
                cap.release()
                cv2.destroyAllWindows()
                exit(0)

2. Python3 读取网络摄像头流

import cv2

if __name__ == "__main__":
	# rtmp 拉流，需要同一个局域网 rtsp://用户名:密码@IP/h265/ch1/main/av_stream
    url = 'rtsp://admin:iot147258369@49.122.47.217/h265/ch1/main/av_stream'
    cap = cv2.VideoCapture(url)
    while 1 > 0:
        ret, frameNow = cap.read()
        if ret:
            cv2.resize(frameNow, (0, 0), fx=0.5, fy=0.5)
            img = cv2.resize(frameNow, dsize=(400, 400))
