@mux/next-video v0.5.0

next-video

Next video is a react component for adding video to your next.js application. It extends both the <video> element and your Next app with features for automatic video optimization.

• Smart storage: Store large video files outside of your git repo
• Auto optimized: Automatically optimize video files and deliver via CDN for better playback performance and quality
• Customizable UI: Choose from themes or build your own player controls
• Posters & Previews: Zero-config placeholder images and timeline hover thumbnails
• Wider compatibility: Use videos that aren’t supported natively by all browsers
• Analytics built-in (optional): See how often videos get watched and track video peformance
• AI-powered: Whisper captions coming soon...

import Video from 'next-video';
import myVideo from '/videos/myVideo.mp4';

export default function Page() {
  return <Video src={myVideo} />;
}

Setup

Install the package

cd your-next-app

# If your project is using NPM (the default for Next.js)
npm install next-video

# If your project is using Yarn
yarn add next-video

# If your project is using pnpm
pnpm add next-video

Run the init wizard

npx next-video init

This will (with prompting):

• install next-video as a dependency
• update your next.config.js file
• if you're using TypeScript, add types for your video file imports
• create a /videos directory in your project which is where you will put all video source files.

It will also add a .gitignore file to the /videos directory that ignores video files. Videos, particularly any of reasonable size, shouldn't be stored/tracked by git. Alternatively, if you'd like to store the original files you can remove the added gitignore lines and install git-lfs.

Remote storage and optimization

Vercel recommends using a dedicated content platform for video because video files are large and can lead to excessive bandwidth usage. By default, next-video uses Mux, which is built by the the creators of Video.js, powers popular streaming apps like Patreon, and whose video performance monitoring is used on the largest live events in the world.

• Sign up for Mux
• Create an access token
• Add environment variables to .env.local (or however you export local env variables)

# .env.local
MUX_TOKEN_ID=[YOUR_TOKEN_ID]
MUX_TOKEN_SECRET=[YOUR_TOKEN_SECRET]

If you choose to do things manually

Add Next Video to next.config.js

/** @type {import('next').NextConfig} */
const { withNextVideo } = require('next-video/process');

const nextConfig = {}; // Your current Next Config object

module.exports = withNextVideo(nextConfig);

Add video import types to tsconfig.json

This is only required if you're using TypeScript, and makes sure your video file imports don't yell at you for missing types. video.d.ts should have been created in your project root when you ran npx next-video init, if not you can create it manually:

// video.d.ts
/// <reference types="next-video/video-types/global" />

Then add that file to the include array in tsconfig.json.

{
  // ...
  "include": ["video.d.ts", "next-env.d.ts", /* ... */ ]
  // ...
}

Usage

Local videos

Add videos locally to the /videos directory then run npx next-video sync. The videos will be automatically uploaded to remote storage and optimized. You'll notice /videos/[file-name].json files are also created. These are used to map your local video files to the new, remote-hosted video assets. These json files must be checked into git.

npx next-video sync

You can also add next-video sync -w to the dev script to automatically sync videos as they're added to /videos while the dev server is running.

// package.json
  "scripts": {
    "dev": "next dev & npx next-video sync -w",
  },

Now you can use the <Video> component in your application. Let's say you've added a file called awesome-video.mp4 to /videos

import Video from 'next-video';
import awesomeVideo from '/videos/awesome-video.mp4';

export default function Page() {
  return <Video src={awesomeVideo} />;
}

While a video is being uploaded and processed, <Video> will attempt to play the local file. This only happens during local development because the local file is never uploaded to your git repo.

Remote videos

For videos that are already hosted remotely (for example on AWS S3), import the remote URL and refresh the page. This creates a local JSON file in the /videos folder and the sync script will start uploading the video.

import Video from 'next-video';
import awesomeVideo from 'https://www.mydomain.com/remote-video.mp4';

export default function Page() {
  return <Video src={awesomeVideo} />;
}

If the hosted video is a single file like an MP4, the file will be automatically optimized for better deliverability and compatibility.

Alternative

In some cases you might not have the remote video URL's available at the time of import.

That can be solved by creating a new API endpoint in your Next.js app for /api/video with the following code.

App router (Next.js >=13)

// app/api/video/route.js
export { GET } from 'next-video/request-handler'

Pages router (Next.js)

// pages/api/video/[[...handler]].js
export { default } from 'next-video/request-handler'

Then set the src attribute to the URL of the remote video, refresh the page and the video will start processing.

import Video from 'next-video';

export default function Page() {
  return <Video src="https://www.mydomain.com/remote-video.mp4" />;
}

Trying it out locally

If you want to develop on this thing locally, you can clone and link this sucker. Just know...it's not a great time right now.

1. Clone this repo
2. cd into the repo
3. npm install && npm run build
4. cd ../ (or back to wherever you want to create a test app)
5. npx create-next-app
6. cd your-next-app
7. npx link ../next-video (or wherever you cloned this repo)
