I've found nginx-accesskey module 
quite useful for this.

something like:

        location ~ \.flv$ {
            accesskey   on;
            accesskey_hashmethod        md5;
            accesskey_arg       "key";

            accesskey_signature "secret_$remote_addr";

in the config and  then the link would be 

http://host/download.php?key=<md5 hash of secret_REMOTE_ADDR>

mind you, the link will be available indefinitely (ie will not expire) 
and won't work if the users REMOTE_ADDR changes between requests (eg is 
behind a round-robin cluster of proxies).
But perhaps another variable can control both these factors..
