In html file, use the video tags

Your browser does not support the video tag.

and in php file, use the following function

 $end) ? $end : $c_end;
        if ($c_start > $c_end || $c_start > $size - 1 || $c_end >= $size) {
            header('HTTP/1.1 416 Requested Range Not Satisfiable');
            header("Content-Range: bytes $start-$end/$size");
            exit;
        }
        $start = $c_start;
        $end = $c_end;
        $length = $end - $start + 1;
        fseek($stream, $start);
        header('HTTP/1.1 206 Partial Content');
        header("Content-Length: ".$length);
        header("Content-Range: bytes $start-$end/".$size);
        //stream
	    $i = $start;
	    set_time_limit(0);
	    while(!feof($stream) && $i <= $end && connection_aborted() == 0) {
	        $bytesToRead = $buffer;
	        if(($i+$bytesToRead) > $end) {
	            $bytesToRead = $end - $i + 1;
	        }
	        $data = fread($stream, $bytesToRead);
	        echo $data;
	        flush();
	        $i += $bytesToRead;
	    }
    }
    else
    {
        header("Content-Length: ".$size);
        readfile($path);
    }
    //end stream
    fclose($stream);
    exit;
}
