error upload video & musci

Hi, i have try to upload a wav file, but the system give me a "uploading file error", but if i upload a mp3 it's all ok.

And if i try to upload video (mp4 for example) i have the same error.

I have changed the ffmpeg for Windows, and changed the execution time to 300 seconds, but i have the "uploading file error". Why? can you hel me?

thanks

I have changed my php.ini with this value:

upload_max_filesize 300M
php_value post_max_size 300M
php_value max_input_time 3000
php_value max_execution_time 3000
php_value memory_limit 128M

in ray/modules/global/inc/db.inc.php after the line @mysql_select_db($this->sDb, $this->rLink);

i insert:

mysql_query ("SET @@local.wait_timeout=9000;");
mysql_query ("SET @@wait_timeout=9000;");
mysql_query ("SET @@local.interactive_timeout=9000;");
mysql_query ("SET @@interactive_timeout=9000;");
mysql_query ("SET @@local.connect_timeout=9000;");
mysql_query ("SET @@connect_timeout=9000;");

my safe_mode is off

exec can be use

the script:
echo "<br/><br/><b>ffmpeg output</b><pre>";
$s = realpath("ray/modules/global/app/ffmpeg.exe");
echo $s."<br>";
echo `"$s" -version 2>&1`;

give me:
