I recently launched a Wowza Server on EC2 with a prebuilt startup package. I can do live streaming easily from an RTMP encoder, however if I push another channel using the same encoder, the second channel doesn't stream. I tried sending another live stream from a different RTMP encoder and it worked. Please note that the two (2) RTMP encoders are from different location with different IP. When I tried to stream from another RTMP encoder on the same network as the first encoder (using one public IP), it doesn't stream. Is there any configurations that I missed during the setup to allow multiple stream from same source?
