四、RTMP Client
RTMP客户端使用videojs实现了在浏览器中的展示，demo如下

RTMP客户端使用python

​

import cv2
import threading
import time
import win32gui,win32con


class Producer(threading.Thread):
    """docstring for Producer"""

    def __init__(self, rtmp_str):

        super(Producer, self).__init__()

        self.rtmp_str = rtmp_str

        # 通过cv2中的类获取视频流操作对象cap
        self.cap = cv2.VideoCapture(self.rtmp_str)

        # 调用cv2方法获取cap的视频帧（帧：每秒多少张图片）
        # fps = self.cap.get(cv2.CAP_PROP_FPS)
        self.fps = self.cap.get(cv2.CAP_PROP_FPS)
        print(self.fps)

        # 获取cap视频流的每帧大小
        self.width = int(self.cap.get(cv2.CAP_PROP_FRAME_WIDTH))
        self.height = int(self.cap.get(cv2.CAP_PROP_FRAME_HEIGHT))
        self.size = (self.width, self.height)
        print(self.size)

        # 定义编码格式mpge-4
        self.fourcc = cv2.VideoWriter_fourcc('M', 'P', '4', '2')

        # 定义视频文件输入对象
        self.outVideo = cv2.VideoWriter('saveDir1.avi', self.fourcc, self.fps, self.size)

    def run(self):

        print('in producer')

        ret, image = self.cap.read()

        while ret:
            # if ret == True:

            self.outVideo.write(image)

            cv2.imshow('video', image)

            cv2.waitKey(int(1000 / int(self.fps)))  # 延迟

            if cv2.waitKey(1) & 0xFF == ord('q'):

                self.outVideo.release()

                self.cap.release()

                cv2.destroyAllWindows()

                break

            ret, image = self.cap.read()


if __name__ == '__main__':

    print('run program')
    # rtmp_str = 'rtmp://live.hkstv.hk.lxdns.com/live/hks'  # 经测试，已不能用。可以尝试下面两个。
    # rtmp_str = 'rtmp://media3.scctv.net/live/scctv_800'  # CCTV
    rtmp_str = 'rtmp://58.200.131.2:1935/livetv/hunantv'  # 湖南卫视

    producer = Producer(rtmp_str)  # 开个线程
    producer.start()
