• Stream sent via FFMPEG (NodeJS) to RTMP (YouTube) not being received

  10 décembre 2024, par Qumber

  I am writing a very basic chrome extension that captures and sends video stream to a nodeJS server, which in turns sends it to Youtube live server.

  


  Here is my implementation of the backend which receives data via WebRTC and send to YT using FFMPEG :

  


  const express = require('express');
const cors = require('cors');
const { RTCPeerConnection, RTCSessionDescription } = require('@roamhq/wrtc');
const { spawn } = require('child_process');

const app = express();
app.use(express.json());
app.use(cors());

app.post('/webrtc', async (req, res) => {
  const peerConnection = new RTCPeerConnection();

  // Start ffmpeg process for streaming
  const ffmpeg = spawn('ffmpeg', [
    '-f', 'flv',
    '-i', 'pipe:0',
    '-c:v', 'libx264',
    '-preset', 'veryfast',
    '-maxrate', '3000k',
    '-bufsize', '6000k',
    '-pix_fmt', 'yuv420p',
    '-g', '50',
    '-f', 'flv',
    'rtmp://a.rtmp.youtube.com/live2/MY_KEY'
  ]);

  ffmpeg.on('error', (err) => {
    console.error('FFmpeg error:', err);
  });

  ffmpeg.stderr.on('data', (data) => {
    console.error('FFmpeg stderr:', data.toString());
  });

  ffmpeg.stdout.on('data', (data) => {
    console.log('FFmpeg stdout:', data.toString());
  });

  // Handle incoming tracks
  peerConnection.ontrack = (event) => {
    console.log('Track received:', event.track.kind);
    const track = event.track;

    // Stream the incoming track to FFmpeg
    track.onunmute = () => {
      console.log('Track unmuted:', track.kind);
      const reader = track.createReadStream();
      reader.on('data', (chunk) => {
        console.log('Forwarding chunk to FFmpeg:', chunk.length);
        ffmpeg.stdin.write(chunk);
      });
      reader.on('end', () => {
        console.log('Stream ended');
        ffmpeg.stdin.end();
      });
    };

    track.onmute = () => {
      console.log('Track muted:', track.kind);
    };
  };

  // Set the remote description (offer) received from the client
  await peerConnection.setRemoteDescription(new RTCSessionDescription(req.body.sdp));

  // Create an answer and send it back to the client
  const answer = await peerConnection.createAnswer();
  await peerConnection.setLocalDescription(answer);

  res.json({ sdp: peerConnection.localDescription });
});

app.listen(3000, () => {
  console.log('WebRTC to RTMP server running on port 3000');
});



  


  This is the output I get, but nothing gets sent to YouTube :

  I do not understand what I am doing wrong. Any help would be appreciated.

• first audio lost when using ffmpeg to overlay one mp4 on top of a big mp4

  11 septembre 2024, par James Hao

  I searched a lot (including chatgtp and google), and tried a lot of methods, not work.&#xA;below is my ffmpeg command line on windows 10 :

  &#xA;

  ffmpeg -i video.mp4 -i b-.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS[b1];[1:v]scale=300:-1,setpts=PTS-STARTPTS+0.0/TB[top];[b1][top]overlay=x=50:y=50:enable='between(t\,0.0,5)'[outv];[1:a]adelay=0|0[a1]; [0:a][a1]amerge=inputs=2[outa]" -map "[outv]" -map "[outa]" -pix_fmt yuv420p -c:a aac -ac 2 -c:v libx264 -crf 18 final_video6.mp4


  &#xA;

  two mp4 files, b-.mp4 should be on top of video.mp4 and play from 0th second and scale to 300 :-1, [0:a][a1]amerge is to merge two audio from the mp4 files, using "-ac 2" to replace pan statement according to enter link description here

  &#xA;

  in result mp4 file, the audio from video.mp4 is lost ; sometimes with the same instruction, but replace b-.mp4 with another mp4 file, the audio may partially lost. any help will be very appreciated.&#xA;below is the console output from ffmpeg :
