Nextjs/React/JS How compress video file uploaded by user through input (client side preferred)
1er novembre 2022, par vana22I have made a basic app where the user can upload a video file through an input.
As you can see in the code i also retrieve the duration and the size of the initial video.


Now the question is, how i can compress the video file in the function "compressvid" so that the size of the video becomes massively smaller (at later stage i want to upload these videos to firebase firestore).
I'e read something about ffmpeg but wasn't able to figure out how to use it here.
I prefer it to be client side as the videos a client can upload are at max 30sec long.
If client side is not possible how would it work server side ?


import Head from 'next/head'
import styles from '../styles/Home.module.css'
import { useState, useEffect } from 'react'

export default function Home() {

 const [videofile, setVideo] = useState("")
 const [viddur, setviddur] = useState("")


 useEffect(() => {
 // only run this if videofile exists
 if (videofile != "") {
 console.log("compress video now ")
 console.log(videofile.type)


 // get duration of video by creating a theoretical video component
 var video = document.createElement('video');
 video.preload = 'metadata';
 video.onloadedmetadata = function() {
 window.URL.revokeObjectURL(video.src);
 // here now can check if video is too long
 setviddur(video.duration)
 }
 video.src = URL.createObjectURL(videofile)
 
 }
 }, [videofile]);

 const clickedvideo = () => {
 console.log("clicked video")
 }

 const compressvid = () => {
 // here need to compress the video so that the size is smaller: preferred client-side; if that's not possible howis it posssible server side or with a cheap api
 }

 return (
 <div classname="{styles.container}">
 
 
 
 
 

 <main classname="{styles.main}">
 <h1 classname="{styles.title}">
 Video compressor
 </h1>
 <p>Size of video before: {videofile.size}</p>
 <p>Duration of video: {viddur}</p>
 <p>Size of video after: { }</p>
 <input classname="{styles.videoinput}" type="file" accept="video/mp4,video/x-m4v,video/*" />> setVideo(e.target.files[0])}>
 <div>
 {(videofile != "") ? <video autoplay="autoplay" loop="loop" src="{URL.createObjectURL(videofile)}" width="300px" height="300px"></video> : null}
 </div>
 </main>
 </div>
 )
}


I tried to compress a video uploaded by a user but didn't figure out how to solve it.

FFMPEG concatenate multiply files with various extensions and properties
28 juillet 2022, par KRUKI'm trying to create a movie on Windows using ffmpeg from files that are from different devices and in different extensions (.mp4, .mov). Is there any way to combine any file extensions into one final movie that will play properly ?


I'm thinking of such an approach, to first normalize all files to the same format (What is the recommended final format ?) and only then combine them into a final file.


I am experimenting with this approach :


ffmpeg -i [input.anyFormatX] outputX.mp4


and then


ffmpeg -f concat -i [List of files] output.mp4


But unfortunately this does not work for all files, should pay attention to the codecs or maybe some other intermediate format ? The biggest problem appears with files recorded with Iphone and in extension .mov. After the first stage, these videos look overburnt, as if they have a lot of raised brightness, how to correct this ?


Do you know perhaps any generic solution, which would allow the assembly of videos from different devices (including Iphone) and with different parameters such as frame rate or resolution ?
