Correct.

Input >> ffmpeg
- split input to main and monitoring;
- scale monitoring stream to lower resolution
- encode both streams
- provide both outputs to local streaming server
ffmpeg >> local streaming server
- use API to start and stop recordings (or web console, if you do it manually)
- provide streams to CDN or/and provide access to your streams for end users

recorded files >> another ffmpeg (controlled by some script that get
RECORDING COMPLETED event to start ffmpeg process)
- extract audio from recorded file
- save audio into file

Something like this.
