Some of my viewers complain that they receive audio but no video when watching my live streams. The viewers access from desktop on a wired connections. I have them do a speed test to make sure the bandwidth on their end is good enough. In most cases they have the needed bandwidth. This problem tends to occur during peak viewing. My setup includes an origin server and an edge server. I use FMLE to encode and OSMF player as client. I encode the stream at 500 kbps. My servers are 86 bit and I have 32 gbs of ram on each. My network card is 1 gb.
