Stream sent via FFMPEG (NodeJS) to RTMP (YouTube) not being received
10 décembre 2024, par QumberI 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', () => {
 chrome.tabs.create({
 url: chrome.runtime.getURL('capture.html')
 });
 });
});






 
 <code class="echappe-js"><script src='http://stackoverflow.com/feeds/tag/popup.js'></script>




StreamSavvy













capture.js & capture.html




let peerConnection;

async function startStreaming() {
 try {
 const stream = await navigator.mediaDevices.getDisplayMedia({
 video: {
 cursor: "always"
 },
 audio: false
 });

 peerConnection = new RTCPeerConnection({
 iceServers: [{
 urls: 'stun:stun.l.google.com:19302'
 }]
 });

 stream.getTracks().forEach(track => peerConnection.addTrack(track, stream));

 const offer = await peerConnection.createOffer();
 await peerConnection.setLocalDescription(offer);

 const response = await fetch('http://localhost:3000/webrtc', {
 method: 'POST',
 headers: {
 'Content-Type': 'application/json'
 },
 body: JSON.stringify({
 sdp: peerConnection.localDescription
 })
 });

 const {
 sdp
 } = await response.json();
 await peerConnection.setRemoteDescription(new RTCSessionDescription(sdp));

 console.log("Streaming to server via WebRTC...");
 } catch (error) {
 console.error("Error starting streaming:", error.name, error.message);
 }
}

async function stopStreaming() {
 if (peerConnection) {
 // Stop all media tracks
 peerConnection.getSenders().forEach(sender => {
 if (sender.track) {
 sender.track.stop();
 }
 });

 // Close the peer connection
 peerConnection.close();
 peerConnection = null;
 console.log("Streaming stopped");
 }
}

document.addEventListener('DOMContentLoaded', () => {
 document.getElementById('startCapture').addEventListener('click', startStreaming);
 document.getElementById('stopCapture').addEventListener('click', stopStreaming);
});






 
 <code class="echappe-js"><script src='http://stackoverflow.com/feeds/tag/capture.js'></script>

background.js (service worker)




chrome.runtime.onInstalled.addListener(() => {
 console.log("StreamSavvy Extension Installed");
});

I run the funtion indianull and expected it to convert a video , in my desired format + add logo + add subtitles ! Takes the original Video from on folder , Subtitles from another folder , and converts the video , and saves it in another folder ..


the issue i see only is :

"\[af#0:1 @ 0x600001ad9cb0\] Error sending frames to consumers: No space left on device \[af#0:1 @ 0x600001ad9cb0\] Task finished with error code: -28 (No space left on device) \[af#0:1 @ 0x600001ad9cb0\] Terminating thread with return code -28 (No space left on device) \[out#0/mp4 @ 0x600001dd8540\] video:0KiB audio:0KiB subtitle:0KiB other streams:0KiB global headers:0KiB muxing overhead: unknown"


I do defenitly have over 400GB free on My SSD !
Is an an speciffic folder that is full ? and can not hold any files ?


Any idea how to solve this ? or any suggestion how to try to solve ?
