RTSP拉流转RTMP推流python代码

在Python中，你可以使用第三方库如`flask-rtsp-rtmp-server`或`gstreamer`结合`PyGSTreamer`来实现RTSP拉流到RTMP推流的过程。下面是一个简单的示例，展示了如何使用Flask和GStreamer进行这种转换：

from flask import Flask, Response
import gi

gi.require_version('Gst', '1.0')
from gi.repository import Gst, GObject

app = Flask(__name__)

@app.route('/rtsp/<path:path>')
def stream_rtmp(path):
    pipeline_str = f"""
        uridecodebin uri={path} ! queue !
        h264parse ! rtph264pay config-interval=1 pt=96 ! rtmpsink location="rtmp://your_rtmp_server/live/stream"
    """
    
    # 创建GStreamer上下文
    bus = Gst.Bus()
    pipeline = Gst.parse_launch(pipeline_str)
    pipeline.set_state(Gst.State.PLAYING)

    def generate():
        while True:
            message = bus.timed_pop_filtered(Gst.Timeout.PEEK, Gst.MessageType.EOS | Gst.MessageType.ERROR)
            if message is not None:
                if message.type == Gst.MessageType.ERROR:
                    print("Error:", message.parse_error())
                    break
                elif message.type == Gst.MessageType.EOS:
                    break
            else:
                buffer = pipeline.get_by_name("rtph264pay").get_buffer()
                yield (buffer, Gst.BufferFlags.FLUSH)

    return Response(generate(), mimetype='multipart/x-mixed-replace; boundary=frame')

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)  # 运行在本地的5000端口
