I've a PHP script that it's being called with a cron job in my server to run uploaded video conversions. It works fine for some videos, but when the video is a bit larger (21MB for example) I get a <code>500 Internal Server Error</code> and no other output. I think that it's possible that this problem was due to timeouts so I've added <code>set_time_limit(9000)</code> and also <code>ini_set('max_execution_time', 9000)</code> to prevent this, but this does not solve anything. I execute ffmpeg using: <pre><code>$cmdOut = shell_exec ('ffmpeg -y -i [....] 2>&1'); // [....] is the rest of the command, it works fine with other videos, so i assume that it works ok. echo print_r($cmdOut); </code></pre> However there is no output, and the following lines are not being executed, so after the <code>shell_exec</code> the script is aborted. Looking at the apache error_log I can see this line: <pre><code>[Wed Jan 12 00:12:46 2011] [error] [client xx.xxx.xxx.xxx] Premature end of script headers: index.php </code></pre> But there are no other clues. Can anyone help me? For testing purposes i've created this PHP script: <pre><code><?php set_time_limit(300); sleep(120); echo "SLEEP OUT"; ?> </code></pre> This script causes a "500 Internal Server Error" when i call it from my web browser, so i suppose that set_time_limit is not working. If i put sleep(30) it works and it returns the text SLEEP OUT. So the question is, how can i avoid the timeout error to execute a PHP script that is taking 5 or 10 minutes to complete?? NOTE: Server is CentOS running apache and php as FastCGI module.
