Abstract
A video production device is deployed to produce a video production stream of an event occurring within an environment that includes a plurality of different video capture devices capturing respective video input streams of the event. The video production device is programmed and operated to: receive video input streams from the video capture devices; determine, for each video capture device, an average root mean square (RMS) audio energy value over a period of time, to obtain device-specific average RMS values for the video capture devices; compare each device-specific average RMS value against a respective device-specific energy threshold value; identify which input stream is associated with an active speaker, based on the comparing step; select one of the identified streams as a current video output stream; and provide the selected stream as the current video output stream.
