Error transcoding with FFmpeg : Error : Output format hls is not available
6 mai 2024, par asif mohmdI am using FFmpeg library to transcode a video file into multiple resolutions and create an HLS (HTTP Live Streaming) master playlist.


It takes a video file as input but its does give me the output with HLS playlist.I got a error called "Output format hls is not available". Only the Output directory is creating


I am using FFMpeg 7.0 full build version and also tried older versions and ffmpeg essentials and also tried chocolatey.


if i remove the implementation of HLS from this code.it will create 4 different resolution videos in my output.


Note:I just tried this same code on my friend MAC Book by only changing the setffmpegPath : "ffmpeg.setFfmpegPath("C :\ffmpeg\bin\ffmpeg.exe") ;" to his ffmpeg directory.
Its working perfectly in his mac book


import "dotenv/config";

 const randomName = (bytes = 32) =>
 crypto.randomBytes(bytes).toString("hex");
 const fileName = randomName();

 if (!fs.existsSync(directoryPath)) {
 fs.mkdirSync(directoryPath, { recursive: true });
 }

 const paths = await new Promise<any>((resolve, reject) => {

I am using Windows 11 and FFMpeg version 7.0. I repeatedly checked, using CMD commands, that my FFMpeg was installed correctly and confirmed the environment variables path, experimented with various FFMpeg versions, and tried with FFMpeg full build Chocolatey package.


In Command Line its working perfectly :

node.js ffmpeg spawn child_process unexpected data output and not possible to kill or stop
1er septembre 2021, par PLNR
I'm rather new to backend stuff, so please excuse, if my question is trivial.

For an Intranet project, I want to present a video element in a webpage (React, HLS.js Player) with the possibility reload the stream in case it hung.

The video sources are mpeg-ts streams delivered as udp multicast.

A small node.js / express server should handle the ffmpeg commands, to transcode the multicast to hls to display them in a browser.



My Problem is, that I am unable to stop the process...

I've tried to SIGINT, SIGTERM the process with it's pid, but the encoding is just going on.

Here is the code I wrote for transcoding so far :


const express = require("express");
const { spawn, exec } = require("child_process");
const cors = require("cors");
const process = require("process")

let ls;
let pid;

const app = express();

app.use(cors());

app.get('/cam/:source', (body) => {
 const cam = body.params.source;
 console.log(cam);

 let source = "udp://239.1.1.1:4444";
 let stream = "/var/www/html/streams/tmp/cam1.m3u8"


 stream = spawn("ffmpeg", ["-re", "-i", source, "-c:v", "libx264", "-crf", "21", "-preset", "veryfast", "-c:a", "aac", "-b:a", "128k", "-ac", "2", "-f", "hls", "-hls_list_size", "5", "-hls_flags", "delete_segments", stream], {detached: true});

 pid = stream.pid;

 stream.stdout.on("data", data => {
 console.log(`stdout: ${data}`);
 });

 stream.stderr.on("data", data => {
 console.log(`stderr: ${data}`);
 console.log("pid: ", pid);
 });

 stream.on("error", error => {
 console.log(`error: ${error.message}`);
 });

 stream.on("close", code => {
 console.log(`child process exited with code ${code}`);
 });
})

app.get('/cam/quit', () => {
 process.kill(pid, 'SIGINT')
})

app.listen(5000, ()=> {
 console.log('Listening');
})


On requesting the /cam/quit i would expect the process to stop... but it doesn't.

I've tried :

app.get('/cam/quit', () => {
 process.kill(pid, 'SIGINT')
})


app.get('/cam/quit', () => {
 process.kill(stream.pid, 'SIGINT')
})


app.get('/cam/quit', () => {
 stream.kill(pid, 'SIGINT')
})


app.get('/cam/quit', () => {
 stream.kill(0, 'SIGINT')
})


But none of this worked... do I miss something ? Is there something I need to change ?


Problem 2 - Output :

The output is emitted on stderr... even the process is working as expected.

This is maybe only cosmetics, but it makes me wondering.

Here is the terminal output :
