Question

我正在尝试直接播放位于远程服务器上的视频（本例中为www.nowvideo.eu），使用curl（）和preg_match（）获取视频直接URL，然后使用找到的下载脚本{ {3}}直接将.php文件显示为视频文件本身。

下载视频有效，但是当我尝试将一个参数'file = video_file.php'添加到jwplayer时，我收到此错误：“ 任务队列在步骤5失败：无法加载播放列表跨域政策限制。 “ 我有一个crossdomain.xml文件，它设置为允许从所有域访问，但我不知道为什么它甚至很重要因为video_file.php与play.php在同一个域中（包含jw播放器代码）。

以下是 video_file.php 的代码：

<?php
$url = 'http://www.nowvideo.eu/video/qdu0vx7m3m3xd';
$content = curl($url);
preg_match('%video/(.[^/]*+)%', $url, $videoID);
preg_match('/filekey="(.[^\"]*?)"/',$content,$key);
$key = str_replace('"','',$key[0]);
$video_data = 'http://www.nowvideo.eu/api/player.api.php?user=undefined&pass=undefined&file='.$videoID[1].'&key='.$key;
$content_key = curl($video_data);
preg_match('/url=(.[^&]*+)/',$content_key,$file);
$file = str_replace('url=','',$file[0]);
download($file,2000);

/*
Set Headers
Get total size of file
Then loop through the total size incrementing a chunck size
*/
function download($file,$chunks){
    set_time_limit(0);
    header('Content-Description: File Transfer');
    header('Content-Type: video/x-flv');
    header('Content-disposition: inline; filename='.basename($file));
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Expires: 0');
    header('Pragma: public');
    $size = get_size($file);
    header('Content-Length: '.$size);

    $i = 0;
    while($i<=$size){
        //Output the chunk
        get_chunk($file,(($i==0)?$i:$i+1),((($i+$chunks)>$size)?$size:$i+$chunks));
        $i = ($i+$chunks);
    }

}

function curl($url){  
    $ch = curl_init();  
    curl_setopt($ch, CURLOPT_URL, $url);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
    $result = curl_exec($ch);  
    curl_close($ch);  
return $result;
}

//Callback function for CURLOPT_WRITEFUNCTION, This is what prints the chunk
function chunk($ch, $str) {
    print($str);
    return strlen($str);
}

//Function to get a range of bytes from the remote file
function get_chunk($file,$start,$end){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $file);
    curl_setopt($ch, CURLOPT_RANGE, $start.'-'.$end);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
    curl_setopt($ch, CURLOPT_WRITEFUNCTION, 'chunk');
    $result = curl_exec($ch);
    curl_close($ch);
}

//Get total size of file
function get_size($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_NOBODY, true);
    curl_exec($ch);
    $size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
    return intval($size);
}
?>

以下是 play.php 的代码：

<html>
<head>
</head>
<body>
<object id="flashplayer" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="830" height="490">
<param name="movie" value="http://example.com/player.swf">
<param name="allowFullScreen" value="true">
<param name="allowScriptAccess" value="always">
<param name="FlashVars" value="file=http://example.com/video_file.php&autostart=true&smoothing=true&stretching=exactfit">
<embed name="flashplayer" src="http://example.com/player.swf" flashvars="file=http://example.com/video_file.php&autostart=true&smoothing=true&stretching=exactfit" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="830" height="490">
</object>
</body>
</html>

crossdomain.xml 的代码（位于root上）：

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM
"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" secure="false"/>
<allow-http-request-headers-from domain="*" headers="*" secure="false"/>
</cross-domain-policy>

有什么想法吗？

变化：

＆安培;拉伸= exactfit

要：

＆安培;拉伸= exactfit＆安培;提供商=视频

现在，这将在JW播放器中工作（我假设你在这里使用JW5）。

使用PHP作为'file ='参数将视频文件从远程URL传递到jwplayer
