Creating a Video with Intermission Images and Audio using FFMPEG and Node.js

If you're looking to create a video with intermission images and audio using FFMPEG and Node.js, there are several ways to achieve this. In this article, we'll explore how to use the `fluent-ffmpeg` library in Node.js to create such a video.

Prerequisites

Before we dive into the code, make sure you have installed the required dependencies by running the following command:

```

npm install express fluent-ffmpeg ffmpeg-installer/ffmpeg hls-server

```

This will install the necessary frameworks and modules for this project.

Setting Up FFmpeg

FFmpeg is a powerful tool for video processing, and it's essential to have it installed on your system. If you haven't already, you can install it using the following command:

```

npm install ffmpeg-static

```

Once installed, you can set the `FFMPEGPATH` environment variable to specify the path to the FFmpeg executable.

Creating the Video

To create a video with intermission images and audio using FFMPEG and Node.js, we'll use the `fluent-ffmpeg` library. Here's an example code snippet that demonstrates how to achieve this:

```javascript

const ffmpegStatic = require('ffmpeg-static');

const ffmpeg = require('fluent-ffmpeg');

// Tell fluent-ffmpeg where it can find FFmpeg

ffmpeg.setFfmpegPath(ffmpegStatic);

// Input file

const input = 'video.mp4';

// Scale the video to 720 pixels in height

const scale = '-vf', 'scale=-2:720';

// Output file

const outputOptions = '-c:v libx264 -crf 18';

// Set up the intermission image and audio

const intermissionImage = 'intermission_image.jpg';

const intermissionAudio = 'intermission_audio.mp3';

// Create a new FFmpeg stream

const stream = ffmpeg(input)

.setFormat('mp4')

.addOutputOptions(outputOptions)

.addInputOption(scale);

// Set up the on progress callback

stream.on('progress', (progress) => {

console.log(`Progress: ${progress.targetSize} / ${progress.size}`);

});

// Run the FFmpeg command and save the output to a file

stream.saveToFile('output.mp4');

```

This code snippet sets up an FFmpeg stream, scales the input video to 720 pixels in height, adds intermission images and audio, and saves the output to a new file named `output.mp4`.

In this article, we've demonstrated how to create a video with intermission images and audio using FFMPEG and Node.js. By using the `fluent-ffmpeg` library and setting up the FFmpeg stream correctly, you can easily create complex videos like this one. Whether you're looking to add intermission slides or more advanced features like subtitles or fade-in/fade-out transitions, this library provides a powerful toolset for video processing in Node.js.
