<?php

        /*$file = "d.mp4";
        $file_size = filesize($file);
        $fp = fopen($file, "rb");
        $data = fread ($fp, $file_size);
        fclose($fp);
        header ("Content-type: video/mp4");
        echo $data; */

 $path = 'f.mp4';
 if (file_exists($path))
 {
 $size=filesize($path);
 $fm=@fopen($path,'rb');
 $begin=0;
 $end=$size;
 if(isset($_SERVER['HTTP_RANGE'])) {
    if(preg_match('/bytes=\h*(\d+)-(\d*)[\D.*]?/i',
        $_SERVER['HTTP_RANGE'],$matches)){
        $begin=intval($matches[0]);
        if(!empty($matches[1])) {
            $end=intval($matches[1]);
        }
    }
 }
 if($begin>0||$end<$size)
     header('HTTP/1.0 206 Partial Content');
 else
     header('HTTP/1.0 200 OK');
     header("Content-Type: video/mp4");
     header('Accept-Ranges: bytes');
     header('Content-Length:'.($end-$begin));
     header("Content-Disposition: inline;");
     header("Content-Range: bytes $begin-$end/$size");
     header("Content-Transfer-Encoding: binary\n");
     header('Connection: close');
     $cur=$begin;
     fseek($fm,$begin,0);
     while(!feof($fm)&&$cur<$end&&(connection_status()==0))
         {
        print fread($fm,min(1024*16,$end-$cur));
        $cur+=1024*16;
        usleep(1000);
     }
     die();
 }

    ?>

but problem is that it takes few seconds to start vidoe, and user keeps on clicking play button.

What is want is something like loading should be there so that user may understand that vidoe is loading like you tube.

Please help.
