StreamSpot Sync now uses OBS as its encoding software. FMLE is only supported in a limited capacity as needed for legacy customers.
When using StreamSpot Sync to start a broadcast the Flash Media Live program will be started and run from the command line. This will result in seeing a black command window popup. It is important not to close this command window as it will end the stream.
Also, it is important to keep FMLE closed when using automation as two instances of the program can not run at the same time. The automation will close FMLE and restart the broadcast but it may result in a delayed start of your broadcast.
