Next Js background mp4

Question

I want to add background video, format mp4, but NextJS shows error:

./public/video/ocean.mp4 1:0
Module parse failed: Unexpected character '' (1:0)
You may need an appropriate loader to handle this file type, currently 
no loaders are configured to process this file. See 
https://webpack.js.org/concepts#loaders

(Source code omitted for this binary file)

import React, {useEffect, useRef} from "react"
import Layout from "../components/webSite/layout";
import backgroundVideo from "../public/video/ocean.mp4"

const Home = () => {
  const videoRef = useRef()

  useEffect(() => {
    setTimeout(()=>{
      videoRef.current.play()
    },5000)
  }, []);

  return <Layout title={"Home"}>
    <video
        ref={videoRef}
        controls
        width="250"
        loop
        muted
        style={{
          position: "relative",
          width: "100%",
          height: "15rem",
          left: 0,
          top: 0,
        }}>
      <source src={backgroundVideo} type="video/mp4"/>
    </video>
  </Layout>
}

export default Home

Answer 1

Everything that you import in React actually needs a webpack loader that understands the format.

MP4 is not one of those formats. Even if it was, importing an entire video file would be horribly inefficient :-)

Solution: Don't import the video file, instead reference it as an external file that the browser loads over http like any other media file. All files you put in /public can be referenced below the top folder of you web site:

<source src="/video/ocean.mp4" type="video/mp4"/>
