The answer is NO.
You can use iOS front/rear camera or any other iPhones or iPads(up to 4,  by running TopDirectorCam App) as input source. The video encoder is only for the user who want to use traditional camera with HDMI or SDI output.
TopDirector and TopDirectorCam App support RTSP, RTP, UDP, SRT protocol for communication, that means you can also use any other product which supports same protocol as an input source.
For live streaming, TopDirector is using RTMP protocol and will soon support SRT if major video share platforms switch to it in near future.
