Extract information from a video at the time of upload

Question

Uploading any video is the easy part, but I would like to explore this moment of uploading more. I would like to extract some information from the video at the time of uploading. This information would be the time the video has and the amount of MB of it. And I would also like at the time of the upload this extracted information to automatically fill in the inputs related to this information.

What I really want is to extract the information, be it in php, jquery or any other kind of viable medium.

Brief example :

Answer 1

Javascript this is very limited for safety reasons.

The size I know is possible through the this.files[0].size and the name, through this.files[0].name used an Event Handler in jQuery. Then to format to be noticeable you can use a function like this:

function humanFileSize(bytes, si) {
    var thresh = si ? 1000 : 1024;
    if(bytes < thresh) return bytes + ' B';
    var units = si ? ['kB','MB','GB','TB','PB','EB','ZB','YB'] : ['KiB','MiB','GiB','TiB','PiB','EiB','ZiB','YiB'];
    var u = -1;
    do {
        bytes /= thresh;
        ++u;
    } while(bytes >= thresh);
    return bytes.toFixed(1)+' '+units[u];
};

In PHP found this answer which suggests a external library getID3 which supports different formats. Having a look at the page supports the most common formats.

So in PHP it would be:

$getID3 = new getID3;
$file = $getID3->analyze($filename);
echo("Duration: ".$file['playtime_string'].
" / Dimensions: ".$file['video']['resolution_x']." wide by ".$file['video']['resolution_y']." tall".
" / Filesize: ".$file['filesize']." bytes<br />");

You can always use print_r($_FILES["upload"]) to download the file properties and then use what you want ex get the size you have

echo $_FILES["upload"]["size"];

or

$new_var = $_FILES["upload"];
echo $new_var["size"];
