Do I need to use Wowza Transcoder AddOn to remap a stream from one transport protocol to another?
No. The base Wowza Media Server 3 software offers native capability for remapping (i.e., transmultiplexing) H.264 content from one incoming transport protocol type (for example RTMP) to a different outgoing transport protocol (for example HLS). You only need to use Transcoder AddOn if you need to (a) convert a non-H.264 incoming stream to H.264 streams, and/or (b) change the bitrate and/or encoding profile of the incoming stream to different bitrates/prfiles.
