@garlikio/ffmpeg

npm install @garlikio/ffmpeg

For a specific version off FFmpeg: npm install @garlikio/[e-mail]5.0

MacOS Yarn Note: Due to a known bug in Yarn that prevents the creation of the node_modules/.bin/ffmpeg link, you will need to run this after installing:

yarn --check-files --ignore-scripts

Consider adding it to your postinstall script.

Features

Specify the version of the version of this package you and the FFmpeg version.

yarn add @garlikio/ffmpeg@{version}-beta.ffmpeg{ffmpeg_veersion}

Note: Currently only FFmpeg version 5 has been added. Please submit your merge requests for new versions to the install.js file.

Also, only MacOS and Linux support has been added.

Usage

Trigger your own process manually.

import { ffmpegPathSync } from '@garlikio/ffmpeg'
// Async: import { ffmpegPath } from '@garlikio/ffmpeg'
import {spawn} from "child_process";

const ffmpegProcess = spawn(ffmpegPathSync(), ['-version'])

Or, use this FFmpeg wrapper. In this example we're streaming a local file to RTMP

import ffmpeg, { ffmpegPathSync } from '@garlikio/ffmpeg'

const ffmpegArguments = [
  '-re', '-i', '-',
  '-c:v', 'libx264', '-preset', 'fast', '-strict', '-2',
  '-c:a', 'aac', '-b:a', '128k',
  '-f', 'flv',
  '-flvflags',  'no_duration_filesize',
    "rtmps://server.test"
]

const ffmpegProcess = ffmpeg(ffmpegArgs);

ffmpegProcess.onOutput((data) => process.stdout.write(data))
ffmpegProcess.onMessage((message) => console.log('message: ', message))
ffmpegProcess.onDisconnect(()=> console.log('Lost connection to ffmpeg'))
ffmpegProcess.onError((error)=> console.log('There was stderror:', error))
ffmpegProcess.onExit(code=> process.exit(code))

/**
 * Stream a file to rtmp
 */
const fileStream = fs.createReadStream("path/to/my.webm")
fileStream.on('error', () => {
  console.error('error')
  process.exit()
})

fileStream.on('open', (data)=> {
  ffmpegProcess.streamOut().on('error', function( err ) {
    console.log('stream out error', err)
    if (err.code === "EPIPE") {
      process.exit(0);
    }
  });

  const streamToRtmp = fileStream.pipe(ffmpegProcess.streamIn())
  streamToRtmp.on('error', (error)=> {
    console.log('stream error', error)
  })
});
