As per the ant media server documentation (Enterprise edition 2.4.0) I could integrate conference video streaming using MCU methodology. I could publish multiple streams to the same room and server would mix/merge the streams to a single stream. As a viewer, when I play the stream in a video element I could see the all the participants video in the room which would look like this PlayDemo Image

I would like to know if there is any possibility to customize the UI like displaying the participant name on every video of the participant or highlighting the participant who is actively talking.

Note that the final stream received will already have the participants video arranged in a default layout as if the UI is already composed with all the participants.
