Your users or your application will need to use two Livepeer.com URLs, an RTMP ingest URL and a playback URL.
An RTMP ingest and playback URL pair references hardware in different parts of the world. This is important because the ingest point should be as physically close to the broadcaster as possible. Each region is three letters, the airport code of the server location. Use the ingest and playback URL pair in the region closest to your broadcaster.
