Hi,
To clear up any possible confusion, is your setup the following:
Inbound RTMP stream (source from FMLE) –> EMS –> Generated HLS chunks –> Apache web server –> Outbound HLS stream –> Client player
And for your backup:
Inbound RTMP stream (source from FMLE) –> EMS –> Generated HLS chunks –> Nginx web server (with RTMP module) –> Outbound HLS stream –> Client player
Is this the case?
Cheers,
IC
