you have to do something like this:
secure_link $arg_token;
secure_link_md5 $remote_addr; (you may include other vars like user-agent, uri, etc...
the link will be like this:
http://www.domain.com/mp4/file.mp4?token=XXX
XXX is the token (have to be the same as secure_link_md5)
which in my example is md5($_SERVER['REMOTE_ADDR'])
secure_link $arg_token;
secure_link_md5 $remote_addr; (you may include other vars like user-agent, uri, etc...
the link will be like this:
http://www.domain.com/mp4/file.mp4?token=XXX
