i have tried this code to upload video and generate thumbnail of particular video but it gives "file fail to upload to" only,if anyone have idea to do it,suggest some solution to perform this task.

Answer 1

here is simple method to create thumb for video

you have to specify paths and thumb will be save .jpg formate

$videos_dir = 'path/to/videos';
$videos_dir = opendir($videos_dir);
$output_dir = 'path/to/output/dir/';
while (false !== ($file = readdir($videos_dir))) {
    if ($file != '.' && $file != '..'){
        $in = $videos_dir.'/'.$file;
        $out = $output_dir.$file.'.jpg';
        exec("/usr/local/bin/ffmpeg -itsoffset -105 -i ".$in." -vcodec mjpeg -vframes 1 -an -f rawvideo -s 100x100 ".$out);
    }
}

<script>
    var vidDOM = $('article').children('video');
    var vid = vidDOM.get(2);
    var canvas = document.getElementById('canvas');
    var ctx = canvas.getContext('2d');

    vidDOM.bind({
        'paused':function () {
            vid.width = canvas.width = vid.offsetWidth;
            vid.height = canvas.height = vid.offsetHeight;
            var $this = this; 
            ctx.drawImage($this, 0, 0, vid.width, vid.height);
            uploadbase64();
        }
    })

    function uploadbase64(){
        canvasData = canvas.toDataURL("image/jpeg"); 
        var ajax = new XMLHttpRequest();
        ajax.open("POST",'ImageUpload.php?filename='+vidDOM.id,false);
        ajax.setRequestHeader('Content-Type', 'application/upload');
        ajax.send(canvasData);
    }
