fluent-ffmpeg

What is fluent-ffmpeg?

The fluent-ffmpeg npm package is a powerful and flexible library for working with FFmpeg, a comprehensive multimedia processing tool. It allows you to perform a wide range of audio and video processing tasks, such as transcoding, format conversion, video editing, and more, using a fluent API.

What are fluent-ffmpeg's main functionalities?

Transcoding

This feature allows you to transcode a video from one format to another. In this example, an MP4 file is transcoded to AVI format.

const ffmpeg = require('fluent-ffmpeg');
ffmpeg('input.mp4')
  .output('output.avi')
  .on('end', () => {
    console.log('Transcoding finished');
  })
  .on('error', (err) => {
    console.error('Error: ' + err.message);
  })
  .run();

Video Editing

This feature allows you to edit videos, such as trimming a segment. In this example, a 10-second segment starting from the 10-second mark of the input video is extracted.

const ffmpeg = require('fluent-ffmpeg');
ffmpeg('input.mp4')
  .setStartTime('00:00:10')
  .setDuration('10')
  .output('output.mp4')
  .on('end', () => {
    console.log('Video editing finished');
  })
  .on('error', (err) => {
    console.error('Error: ' + err.message);
  })
  .run();

Audio Extraction

This feature allows you to extract audio from a video file. In this example, the audio from an MP4 video is extracted and saved as an MP3 file.

const ffmpeg = require('fluent-ffmpeg');
ffmpeg('input.mp4')
  .output('output.mp3')
  .noVideo()
  .on('end', () => {
    console.log('Audio extraction finished');
  })
  .on('error', (err) => {
    console.error('Error: ' + err.message);
  })
  .run();

Adding Watermarks

This feature allows you to add watermarks to videos. In this example, a text watermark is added to the video.

const ffmpeg = require('fluent-ffmpeg');
ffmpeg('input.mp4')
  .outputOptions('-vf', 'drawtext=text=Watermark:fontcolor=white:fontsize=24:x=10:y=10')
  .output('output.mp4')
  .on('end', () => {
    console.log('Watermark added');
  })
  .on('error', (err) => {
    console.error('Error: ' + err.message);
  })
  .run();

Other packages similar to fluent-ffmpeg

ffmpeg

The ffmpeg npm package is a simple wrapper around the FFmpeg command-line tool. It provides basic functionality for executing FFmpeg commands but lacks the fluent API and higher-level abstractions provided by fluent-ffmpeg.

ffmpeg-static

The ffmpeg-static npm package provides a static binary of FFmpeg for various platforms. It is useful for ensuring that FFmpeg is available in your environment but does not provide any API for interacting with FFmpeg commands directly.

node-ffmpeg

The node-ffmpeg npm package is another wrapper for FFmpeg, offering a more straightforward API for basic tasks like transcoding and format conversion. However, it is less feature-rich and flexible compared to fluent-ffmpeg.
