ffbinaries

ffbinaries downloader

Downloads precompiled ffmpeg, ffprobe, ffplay and ffserver binaries from ffbinaries.com.

This module is cross-platform and can be used through CLI or as a Node module, (either as a build step or in a postinstall script).

You can download whatever binaries you need during the build if you'd like to bundle the binaries with your distributable files or just download it on user's machine during initial setup process.

Reporting issues

If you're experiencing issues please update to the newest version and run ffbinaries clearcache.

If that doesn't resolve it simply raise an issue on GitHub.

Make sure to include the information about which version you're using, platform, the exact commands you're trying to execute and the output.

New syntax

New syntax got introduced in 1.0.0.

With the new syntax binaries to download are specified first (i.e. ffmpeg or ffplay). Platform is now a flag.

This change applies to both command line interface and programmatical usage.

You can see the old syntax documented in v0.1.8.

Usage

You can run it from your code or through CLI.

If output argument is specified the binary will be placed there. It will default to current working directory.

If platform argument is missing then the current platform will be automatically detected and binaries for it will be downloaded.

If components argument is missing then binaries of all available components will be downloaded (see Included components section).

CLI

When installed globally with npm i ffbinaries -g this module will register itself on command line interface.

Arguments

CLI uses the following syntax:

ffbinaries [components] [--platform] [--output] [--quiet] [--version]

Each flag can also be abbreviated in your scripts with -p, -o, -q and -v respectively.

Examples

Download all binaries for your platform

ffbinaries

Download all binaries for a specified platform

ffbinaries -p=mac

Download only ffplay for 64-bit Windows, quiet output

ffbinaries ffplay -p=win-64 --quiet

Download only ffmpeg and ffprobe, version 3.2 for 64-bit Linux, quiet output, save binaries in a specified directory

ffbinaries ffmpeg ffprobe -p=linux-64 -q -v=3.2 --output=/usr/local/bin

Additional commands

There are also ffbinaries help, ffbinaries versions and ffbinaries clearcache.

Programmatically

Methods

ffbinaries library exports the following methods:

• downloadFiles(platform, opts, callback) downloads and extracts the requested binaries.

  The opts parameter is an object that can contain these optional parameters:

  • destination: the path where the binaries will be downloaded to. If not provided it will default to ..
  • components: an array of string values that describes which components to download. If not provided it will default to all components available for the platform.
  • version: version of ffmpeg to download
  • quiet: suppress verbose logs

• getVersionData(version, callback) fetches the full data set without downloading any binaries.

• listVersions(callback) returns the list of available versions from the API

• listPlatforms() returns the list of available platforms

• detectPlatform() returns the platform code of the machine as detected by the module.

• resolvePlatform(input) resolves input to a platform code (matches aliases).

• getBinaryFilename(component, platform) resolves a filename of a binary for a given platform (appends ".exe" in Windows).

• clearCache() purges local cache

Examples

Download all binaries for your platform

var ffbinaries = require('ffbinaries');

ffbinaries.downloadFiles(function () {
  console.log('Downloaded all binaries for current platform.');
});

Download only ffmpeg and ffprobe, version 3.2 for 64-bit Linux, quiet output, save binaries in a specified location

var ffbinaries = require('ffbinaries');
var dest = __dirname + '/binaries';

ffbinaries.downloadFiles(['ffmpeg', 'ffprobe'], {platform: 'linux-64', quiet: true, destination: dest}, function () {
  console.log('Downloaded ffplay and ffprobe binaries for linux-64 to ' + dest + '.');
});

See more examples.

Platforms

The following platform codes are available:

windows-32 (aliases: win, windows, win-32), windows-64 (alias: win-64)
