This object can parse and extract information from AVI video files.
It can take the URL or selected file of a AVI video and read it to parse its information.
The object takes a callback function to handle errors, or if it succeed it calls another callback function passing the parse information in easy to process data structure.
It returns information about the audio and video streams like the format, compatibility, indexation, duration, bitrate, creator, codecs, size, samples, language, frame rate, width height, color depth, etc.. Innovation Award

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 MP4 and MKV video files.

AVIInfo
Sort of "Mediainfo" for AVI Files - little AVIParser (just for main technics information about the file)
Dependances : null
Usage :
<script src="AVIInfo.js" type="text/javascript" charset="utf-8"></script>
(in single file .html)
importScripts('AVIInfo.js');
(in worker)
How use it : 2 ways :
1
avi(this.files[0], function(err, info) {
if (err) {
.....
} else {
sortie_texte = human_reading(info);
....
}
});
2
-------------------------------------------------------------------------------------
avi(this.files[0], withmovis, function(err, info) {
if (err) {
.....
} else {
sortie_texte = human_reading(info);
....
}
});
where 'withmovis' is false or true (false by default or by ignore). When withmovis is true, AVIInfo will calculate sizes by reading each size of each frame. It's more exact but more slower
AVIInfo 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 a single file and no worker : index.html
for multiple files and worker : indexw.html
Try it ?
