我需要python opencv读取rtsp图像处理后推流rtmp的代码

你好，以下是Python OpenCV读取RTSP图像处理后推流RTMP的代码示例：

import cv2
import os

rtsp_url = "YOUR_RTSP_STREAM_URL"
rtmp_url = "YOUR_RTMP_STREAM_URL"

# Open the video stream using OpenCV
cap = cv2.VideoCapture(rtsp_url)

# Define the codec and create VideoWriter object for RTMP streaming
fourcc = cv2.VideoWriter_fourcc(*"mp4v")
out = cv2.VideoWriter(rtmp_url, fourcc, 30.0, (640, 480))

while True:
    ret, frame = cap.read()

    if ret:
        # Display the frame, if needed
        cv2.imshow("frame", frame)

        # Apply your image processing here
        processed_frame = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

        # Write processed frame to video stream
        out.write(processed_frame)

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

# Release resources
cap.release()
out.release()
cv2.destroyAllWindows()

请注意，请替换 "YOUR_RTSP_STREAM_URL" 和 "YOUR_RTMP_STREAM_URL" 为您自己的 RTSP 直播流 URL 和 RTMP 推流地址。此代码演示如何在 Python 下读取 RTSP 视频流并将其处理后推流到 RTMP 服务器。如果您需要更高级的图像处理，请根据您的需求更改 "processed_frame" 变量中的代码。
