You have two locations that match.  It appears that Nginx takes the
first one.   I'd try something like:

location /cache {
    location ~ \.flv$ { flv; }
    error_page 404 = @apache;
}

location @apache {
    proxy_pass http://127.0.0.1:8080;
}


Untested and don't really have time to experiment for you, so YMMV.
