I've already implemented some parts myself. I need help for finishing this project. Up to four teams having three members each, are competing in the quiz. The presenter and the admin direct the flow of the competition. The players, presenter and admin are all located on separate remote locations. Every participant is streaming audio/video from his/her web-camera. Every stream is recorded on the server in a separate file. Server utilizes the OpenVidu PRO which underneath uses Kurento media server. The back-end is already finished. I need some help for finishing the front-end.
