Hi,
Here are the steps you need to follow:
FMLE
1. Start FMLE
2. Put the URL in the In the "FMS URL" field: rtmp://<ems_ip_here>/live
3. Give a name to the stream in the "Stream" field
4. Push the "Start" button at bottom of the window
FMLE should now try to connect
For Wirecast, you need to read more in their documentation.
Also, can you please tell us what is the exact error and where you encounter it (EMS,FMLE,WC)?
Best reagards,
Andrei
