I'm not aware of any feature in rtmpdump or flvstreamer which would enable you to report a false location to the server.

The usual approach is ip spoofing, also known as geo spoofing, whereby you use other means of falsifying your geographical location (hence the name "geo" spoofing!) - shielded behind a proxy perhaps.

Enter "ip spoofing" or "geo spoofing" or "geospoofing" into a popular search engine, limiting your search to whichever operating system you're using, and you'll get a representative sample of usable results.

It's said to be quite easy to do, but I've actually never had occasion to try it.
