SWFUpload Upload Video 500 exception occurred

500 Error SWFUpload uploading video
I use SWFUpload upload video 500 error, what is the problem? For advice
On the index.php page I changed the file_size_limit here: "A few megabytes",
File_Types: "* *", upload 2.63MB size video 500 error

And I am on the upload.php page $extension_whitelist = Array ("Doc", "txt", "jpg", "gif", "docx", "PNG", "WMV", "RMVB", "flv");// Allowed uploads of the file


The path I maintain is not Chinese, is the English state how still appear 500 error?

------Solution--------------------
Check if you have permissions. and the default upload maximum size is 2M, you need to change the upload size limit in php.ini.
