Setting getChannelData causing socket.io to crash in web audio
6 novembre 2014, par Brad.SmithI’m having an issue where whenever I transcode an audio file and send the audio buffer to the client via socket.io to be played by web audio my connection dies as soon as I perform
source.buffer.getChannelData(0).set(audio);I’m assuming that this isn’t a Socket.IO problem and that I’m only seeing the Socket.IO issue as a result of the real problem. In the client I’m piping the audio file into stdin of ffmpeg and listening to stderr of ffmpeg to determine when it’s safe to send the buffer. The client is receiving the buffer and is doing everything properly until the line stated above. Here is some sample test code to reproduce the issue.
Server side :
var express = require('express');
var http = require('http');
var spawn = require('child_process').spawn;
var app = express();
var webServer = http.createServer(app);
var io = require('socket.io').listen(webServer, {log: false});
app.use(express.static(__dirname + '/public'));
app.get('/', function(req, res){
res.send(
"<code class="echappe-js"><script src='http://stackoverflow.com/socket.io/socket.io.js'></script>\n"+
"<script>var socket=io.connect('http://127.0.0.1:3000');</script>\n"+
"<script src='http://stackoverflow.com/webaudio_file_cli.js'></script>"
) ;
) ;
webServer.listen(3000) ;io.sockets.on(’connection’, function(webSocket)
var disconnect = ’0’ ;
var count = 0 ;
var audBuf = new Buffer([]) ;if (disconnect == ’0’)
console.log(’new connection...’) ;var inputStream = spawn(’wget’, [’-O’,’-’,’http://www.noiseaddicts.com/samples/4353.mp3’]) ;
var ffmpeg = spawn(’ffmpeg’, [
’-i’, ’pipe:0’, // Input on stdin
’-acodec’, ’pcm_s16le’, // PCM 16bits, little-endian
’-ar’, ’24000’, // Sampling rate
’-ac’, 1, // Mono
’-f’, ’wav’,
’pipe:1’ // Output on stdout
], stdio : [’pipe’,’pipe’,’pipe’]) ;inputStream.stdout.pipe(ffmpeg.stdin) ;
ffmpeg.stdout.on(’data’, function(data)
audBuf = Buffer.concat([audBuf,data]) ;
) ;ffmpeg.stderr.on(’data’, function(data)
var _line = data.toString(’utf8’) ;
if (_line.substring(0,5) == ’size=’ && _line.indexOf(’headers :’) > -1)
console.log(’completed...’) ;
webSocket.emit(’audio’,audBuf) ;
) ;
webSocket.on(’disconnect’, function()
console.log(’disconnecting...’) ;
disconnect=1 ;
) ;
) ;
Client side (webaudio_file_cli.js) :
window.AudioContext = window.AudioContext || window.webkitAudioContext;
var context = new AudioContext();
var source = context.createBufferSource();
var audioStack = [], audio = [];
socket.on('audio', function(data) {
playAudio(data);
});
function playAudio(data) {
// playback starting...
audioStack = Int16Array(data);
for (var i = 0; i < audioStack.length; i++) {
audio[i] = (audioStack[i]>0)?audioStack[i]/32767:audioStack[i]/32768; // convert buffer to within the range -1.0 -> +1.0
}
var audioBuffer = context.createBuffer(1, audio.length, 24000);
source.buffer.getChannelData(0).set(audio);
source.buffer = audioBuffer;
source.connect(context.destination);
source.start(0);

Why ffmpeg ignores output fps ?
22 novembre 2023, par Thomas CarltonI have the following ffmpeg command that streams an input to an RTMP endpoint :


ffmpeg 
 -re 
 -i - 
 -r 30 
 -vf scale=852:480 
 -c:v libx264 
 -pix_fmt yuv420p 
 -profile:v main 
 -preset veryfast 
 -x264opts "nal-hrd=cbr:no-scenecut" 
 -minrate 3000 
 -maxrate 3000 
 -g 60 
 -c:a aac 
 -b:a 160k 
 -ac 2 
 -ar 44100 
 -f flv 
 Some RTMPURL/ Some RTMPKey


This command works but the output frame rate is not respected. It drops to 6 fps. I need it to be always 30 fps.


Why is it not respected ?

I also tried creating the webpack.config.js file in the root directory of the project but it did not work


<

import webpack from 'webpack'

module.exports = {
 plugins: [
 new webpack.DefinePlugin({
 'process.env.FLUENTFFMPEG_COV': JSON.stringify(false),
 }),
 ],
};


>

This is my src/app/api/new/route.js file code


import { NextResponse, NextRequest } from "next/server";
import ffmpeg from 'fluent-ffmpeg'
var command = ffmpeg()

export function GET(){

 command.input('mp4/video.mp4')
 
 .save('converted/audio.mp3')

 return NextResponse.json('Done')
}


This is next.config.js file


/** @type {import('next').NextConfig} */

const nextConfig = {}

module.exports = nextConfig


This is package.js file


{
 "name": "my-app",
 "version": "0.1.0",
 "private": true,
 "scripts": {
 "dev": "next dev",
 "build": "next build",
 "start": "next start",

 "dependencies": {

 "next": "14.0.2",
 "react": "^18",
 "react-dom": "^18",
 "webpack": "^5.89.0"
 }
}


How to fix this error ?
