Hello,
The Wowza Transcoder addon is supported only for Live streaming.
if you want to implement adaptive bitrate streaming, you will need to generate the different bitrate VOD renditions of the same media file using an encoder tool.
You can follow the instructions from the “How to do adaptive bitrate streaming” forum article describing how to do VOD adaptive bitrate streaming.
You need to make sure the different bitrate renditions are properly key-frame aligned in order for adaptive bitrate delivery to work properly.
You can also check out these FFMPEG instructions on creating the key-frame aligned VOD files:
