Hi,
As mentioned on the FMS error message, you need to add a %i tag to the stream name. For example, if you set the FMS stream name to xstreamtest_live%i, the following stream names will sent by FMS to EMS:
xstreamtest_live1
xstreamtest_live2
xstreamtest_live3
You need to provide all the stream names (separated by commas) in the localstreamnames parameter of the pullstream API command for the EMS.
Cheers,
Don
