  • 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.

    



    


    Optionally Here's the frontend code from the extension, which (to me) appears to be recording and sending the capture :

    


    popup.js & popup.html

    


    

    

    document.addEventListener('DOMContentLoaded', () => {
  document.getElementById('openCapturePage').addEventListener('click', () => {

  • 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&#x2B;0.0/TB[top];[b1][top]overlay=x=50:y=50:enable=&#x27;between(t\,0.0,5)&#x27;[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;

    &#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 :

    I am trying to extract the first frame from a video to save it as a preview.

    &#xA;

    Here's an almost working solution using ffmpeg :

    &#xA;

    func extractFirstFrame(videoBytes []byte) ([]byte, error) {&#xA;    input := bytes.NewReader(videoBytes)&#xA;&#xA;    var output bytes.Buffer&#xA;&#xA;    err := ffmpeg.Input("pipe:0").&#xA;        Filter("select", ffmpeg.Args{"gte(n,1)"}).&#xA;        Output(&#xA;            "pipe:1",&#xA;            ffmpeg.KwArgs{&#xA;                "vframes": 1,&#xA;                "format":  "image2",&#xA;                "vcodec":  "mjpeg",&#xA;            }).&#xA;        WithInput(input).&#xA;        WithOutput(&amp;output).&#xA;        Run()&#xA;&#xA;    if err != nil {&#xA;        return nil, fmt.Errorf("error extracting frame: %v", err)&#xA;    }&#xA;&#xA;    return output.Bytes(), nil&#xA;}&#xA;

    &#xA;

    The problem with this is that it can only process horizontal videos. For some reason it will throw a 0xbebbb1b7 error for a vertical videos. I don't understand why is that, probably because this is my very first time with ffmpeg.

    &#xA;

    Also, I am concerned if this solution is optimal. My assumption is that the whole video will be loaded into the memory first, which is kinda bad and I would like to avoid that

    &#xA;

    I use https://github.com/u2takey/ffmpeg-go, but errors are the same even if I run it using exec :

    &#xA;

        cmd := exec.Command(&#xA;        "ffmpeg",&#xA;        "-i", "pipe:0",&#xA;        "-vf", "select=eq(n\\,0)",&#xA;        "-q:v", "3",&#xA;        "-f", "image2",&#xA;        "pipe:1",&#xA;    )&#xA;

    &#xA;

    Interestingly enough, I noticed that running command in the terminal will work as expected with any type of video ffmpeg -i .\video_2024-08-10_00-03-00.mp4 -vf "select=eq(n\,0)"  -q:v 3 output_image.jpg, so the problem may be on how I send those videos to my server. I useFiber and send videos as multipart/form-data and then read it like this :

    &#xA;

        form_data, err := c.FormFile("image")&#xA;    file, err := form_data.Open()&#xA;    bytes, err := io.ReadAll(file)&#xA;    ....&#xA;    preview, err := extractFirstFrame(bytes)&#xA;&#xA;

    &#xA;

    I also managed to find logs for the failed attempt :

    I also realized that the problem was not related to the video orientation, but to to the video from a specific source uploaded specifically on my server 🤡 Such a weird coincidence that I decided to test my video upload with those files, but anyway. And those are.... Downloaded instagram reels lol. But again, ffmpeg works just fine when ran in terminal
