Many sites need to take videos uploaded by the users. When a user uploads a video he may not be certain if that is the right video that he wants to upload and may only realize that after a few hours when the video finishes uploading.

This object is one of several others that can help addressing this issue by being able to parse and extract data from an MP4 video even before the user uploads it. This way the user can confirm if the video was the right was that he wanted to upload.

Other versions of this package exist for parsing AVI and MKV video files.

Sort of "Mediainfo" for MP4 Files - little MP4Parser (just for main technics information about the file)

Dependances : null

Usage :

<script src="MP4Info.js" type="text/javascript" charset="utf-8"></script> 
(in single file .html)

(in worker)

How use it :

        mp4(this.files[0], function(err, info) {
            if (err) {
            } else {
                sortie_texte = human_reading(info);

MP4Info return an object structured (named 'info') wich contains a lot of technicals information about the file. If we want to read this informations, we need to make them readable. So human_reading is here !

Examples :

for multiple or single file and no worker : index.html

Try it ?   (multiple + worker)       

Bugs :

This version use await/async so Microsoft Internet is forbiden ... but Edge run :-)
More : workers (multiple files) work now in kind of parallelism (not one after one)
