Are you manipulating mp4 files in CakePHP or just serving them? If you’re serving them, then CakePHP won’t touch the files as the webserver (apache/nginx) will handle sending the files to the client. If the files aren’t being sent by the webserver correctly, you may need to add the required media types to your webserver. (AddType on apache for example).
