Larix Screencaster is a mobile app designed to capture the mobile device screen and stream it live using professional protocols like SRT, RTMP, RTSP, RIST and WebRTC. While it’s widely used on specialized hardware like DJI RC Plus, it’s just as powerful and flexible on everyday Android and Apple smartphones and tablets.
