WebRTC to RTMP: A Developer's Guide to Real-Time Streaming Conversion

1# Example: Wowza configuration snippet (pseudo-code)
2<Application>
3  <Name>webrtc-to-rtmp</Name>
4  <Version>1.0</Version>
5  <Description>Converts WebRTC stream to RTMP</Description>

10      <Enable>true</Enable>

1// Example: Node.js (pseudo-code)
2const webrtc = require('wrtc');
3const rtmp = require('node-media-server');
4
5// 1. Establish WebRTC connection
6// 2. Get the MediaStream from WebRTC
7// 3. Configure RTMP server
8// 4. Pipe the MediaStream to RTMP server

10rtmp.run();

12console.log('WebRTC to RTMP server started');

1// Example: WebRTC client-side code (simplified)
2navigator.mediaDevices.getUserMedia({ video: true, audio: true })
3  .then(stream => {
4    const peerConnection = new RTCPeerConnection();
5    stream.getTracks().forEach(track => peerConnection.addTrack(track, stream));
6
7    // ... signaling logic to establish connection with the server ...
8  })
9  .catch(error => console.error('Error accessing media devices:', error));

18    #ffmpeg -i <webrtc_stream> -c copy -f flv rtmp://<rtmp_server>/live/<stream_name>
