html5 / mp4视频从PHP流媒体时无法在移动浏览器中播放

我正在尝试用PHP在移动浏览器上使用html5播放mp4视频。

我使用下面的类:

http://labs.divx.com/node/17030

脚本工作正常，除了对mime_types数组的引用，我必须删除$以使其工作。

无论如何，我的问题是这样的。当我用文件。mp4运行这个脚本时，它在我的手机上运行得很好。

但是一旦我放入代码来验证文件是否被允许播放，等等。(如果客户购买了视频，如果他们已经超过了允许的观看次数等)

文件根本无法加载。

它可以在桌面浏览器中加载。它只在移动浏览器中不加载。

下面是我用来播放文件的代码:

当我像这样运行它时，它可以在桌面浏览器中运行，但不能在移动浏览器中运行:

<?php
apc_clear_cache();
session_start();
require(dirname(__FILE__) . "/../_includes/config.php");
require(dirname(__FILE__) . "/../_includes/validate_session.php");
$id = (int)$_GET['id'];
if (!$result = $mysqli->query('SELECT
orders_item_product_downloadable_videos.id,
orders_item_product_downloadable_videos.current_no_downloads,
DATE_ADD(IF(orders.id IS NOT NULL,orders.date_order,o.date_order),INTERVAL orders_item_product_downloadable_videos.no_days_expire DAY) AS date_expire,
product_downloadable_videos.embed_code,
orders_item_product_downloadable_videos.no_days_expire,

OR
(o.id IS NOT NULL AND o.status IN (1,7) AND o.id_customer = "'.(int)$_SESSION['customer']['id'].'")
)       
LIMIT 1')) throw new Exception('An error occured while trying to get video info.'."'r'n'r'n".$mysqli->mysqli->error);
if (!$result->num_rows) {
//throw new Exception(language('account/order', 'ERROR_DOWNLOAD_EXPIRED'));
exit;   
}       
$row = $result->fetch_assoc();  
$result->free();
if ($row['no_downloads'] > 0 && $row['current_no_downloads'] >= $row['no_downloads']) {
//throw new Exception(language('account/order', 'ERROR_NO_DOWNLOADS_REACHED'));
exit;   
}       
if ($row['no_days_expire'] > 0 && strtotime($row['date_expire']) <= time()) {
//throw new Exception(language('account/order', 'ERROR_DOWNLOAD_EXPIRED'));
exit;               
}
$file = dirname(__FILE__).'/../admin/protected/streaming_videos/'.$row['source'];
require(dirname(__FILE__).'/../_includes/classes/stream.php');
$st = new VSTREAM();
$st->stream(dirname(__FILE__).'/../397d729225599bcda978ac4fd4aaeba2.mp4');

当我像这样注释并运行它时，它可以在移动浏览器中工作，但是为什么呢?

<?php
apc_clear_cache();
session_start();
require(dirname(__FILE__) . "/../_includes/config.php");
require(dirname(__FILE__).'/../_includes/classes/stream.php');
$st = new VSTREAM();
$st->stream(dirname(__FILE__).'/../397d729225599bcda978ac4fd4aaeba2.mp4');

如果我添加validation_session.php代码，它不起作用。

<?php
apc_clear_cache();
session_start();
require(dirname(__FILE__) . "/../_includes/config.php");
require(dirname(__FILE__) . "/../_includes/validate_session.php");
require(dirname(__FILE__).'/../_includes/classes/stream.php');
$st = new VSTREAM();
$st->stream(dirname(__FILE__).'/../397d729225599bcda978ac4fd4aaeba2.mp4');

validation_session.php代码只在里面有:

<?php
if(!$_SESSION['customer']['id']){
    header("Location: /account/login");
    exit;
}
?>

我甚至通过在屏幕上输出不工作的短代码来测试会话，我可以看到$_SESSION['customer']['id']确实存在。

所以我不知道我在这里错过了什么。

如果有人知道为什么这个不工作，我将非常感谢你的输入!

谢谢!
