Change you're header from :
更改您的标题：
header("Content-type:application/octet-stream");
To :
到 ：
header("Content-type: video/flv");
Then you can do :
然后你可以这样做：
header("Content-Disposition:attachment;filename=\"$psp\"");
//allways a good idea to let the browser know how much data to expect
header("Content-length: " . filesize($psp) . "\n\n");
echo file_get_contents($psp); //$psp should contain the full path to the video

If you are looking to allow files to be downloaded instead of streamed then something like this should work. You will obviously need to change the paths.
如果您希望允许下载文件而不是流式传输，那么应该可以使用类似的方法。您显然需要更改路径。
// We'll be outputting a PDF
header('Content-type: application/pdf');
// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="download.pdf"');
// The PDF source is in original.pdf
readfile('original.pdf');
EDIT

In your case it will be something like this.
在你的情况下，它会是这样的。
// We'll be outputting a video
header('Content-type: video/flv');
// It will be called video.flv
header('Content-Disposition: attachment; filename="video.flv"');
// The PDF source is in original.flv
readfile('original.flv');
