【问题描述】：
我有一个在 webroot 之外上传的脚本。然后通过网站将用户链接到图像文档等。
所以对于图片，链接是：
media.php?file=nameoffile.jpg&user=userid&folder=images
然后用于显示图像：
<img src="media.php?file=nameoffile.jpg&user=userid&folder=images" width="100" border="0">
这适用于图像并提供下载文档的链接。
我面临的问题是嵌入，我使用 ffmpeg 将所有允许的视频类型转换为 flv（这些视频经过测试并且效果很好），但是当我尝试嵌入 flv 视频时它永远无法工作（它适用于直接链接文件只是不通过 media.php）。如果可能的话，我还想嵌入 .swf。
我正在使用 jwplayer 嵌入（与文件的直接链接一起工作，而不是通过 media.php）

这里是 media.php：
$path_parts = pathinfo($_SERVER['REQUEST_URI']);
$file = basename(urldecode($_GET['file']));
$user = basename(urldecode($_GET['user']));
$folder = basename(urldecode($_GET['folder']));
$ext = pathinfo($file, PATHINFO_EXTENSION);
$fileDir = 'pathoutsidewebroot';
$filePath = $fileDir . $file;
switch(
$ext) {
case "flv": $ctype="video/x-flv"; break;
// adobe
case "pdf": $ctype="application/pdf"; break;
// ms office
case "doc": $ctype="application/msword"; break;
case "rtf": $ctype="application/rtf"; break;
case "xls": $ctype="application/vnd.ms-excel"; break;
case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
// open office
case "odt": $ctype="application/vnd.oasis.opendocument.text"; break;
case "ods": $ctype="application/vnd.oasis.opendocument.spreadsheet"; break;
default: $ctype = "application/force-download"; break;
}
if(in_array($ext, $valid_formats_vid)){
if (file_exists($filePath)) {
header('Content-Type: ' . mime_content_type($filePath));
header('Content-Length: ' . filesize($filePath));
readfile($filePath);
}
}
else if(in_array($ext, $valid_formats_img)) {
if (file_exists($filePath)) {
header('Content-Type: ' . mime_content_type($filePath));
header('Content-Length: ' . filesize($filePath));
readfile($filePath);
}
}
else if(in_array($ext, $valid_formats_docs)) {
if (file_exists($filePath))
{
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: $ctype");
header("Content-Disposition: attachment; filename=\"".basename($filePath)."\";");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".@filesize($filePath));
set_time_limit(0);
@readfile($filePath) or die("File not found."); }
}

设法通过 media.php 将其更改为这个（但仍然无法正常工作）
header("Content-Type: $ctype");
header('Content-Length: ' . filesize($filePath));
header('Accept-Ranges: bytes');
$now = time( );
$then = gmstrftime("%a, %d %b %Y %H:%M:%S GMT", $now + 365*86440);
header("Expires: $then");
ob_clean();
flush();
readfile($filePath);
