Not treated mp3 and video

Not treated mp3 and video is two hours passed and hanging in the rough in what could be the problem? Looked everywhere php configuration is OK. The permissions set like shown within. 

Try to check if crontab is setup properly. It's better to ask your hosting provider support to check it for you. It should be something like this there:

/path/to/php /path/to/dolphin/periodic/cron.php
