ffdevices

FFDevices for Node.js

List all available media devices on FFmpeg. Supports Windows, OSX and Linux(coming soon)

Installation

Via npm:

$ npm install ffdevices --save

Prerequisites

FFmpeg

You need to have ffmpeg version >= 2.0.7 for this to work. This is the oldest version I tested but it may work on older version also.

Note: If you downloaded the static build most probably FFMPEG_PATH environment variable is not yet set. You have two options:

1. Find the location of the ffmpeg bin directory and add it to your PATH.
2. Set the custom FFMPEG_PATH using the ffdevices.#ffmpegPath

Usage

var ffdevices = require('ffdevices')

ffdevices.getAll(function(error, devices) {
  if(!error) {
    console.log(devices)
  }
})

.ffmpegPath

You can set custom FFMPEG_PATH using ffdevices.ffmpegPath

ffdevices.ffmpegPath = 'C:\\ffmpeg\\bin\\ffmpeg.exe' //PATH to the ffmpeg file.

ffdevices.getAll(function(error, devices){
  if(!error) {
    console.log(devices)
  }
})

.gdigrab(Windows only)

gdigrab is the desktop capturer for windows. By default it is enabled, you can disable it if you don't want to include it. Pass this command before you call .getAll().

ffdevices.gdigrab = false
ffdevices.getAll(...)

Sample Windows result
