Live channel from mp4

I am just wondering if I can create live streaming channel from multiple mp4
files and loops indefinitely with Flussonic Media Server

Sure, this task can be implemented with server-side playlists:

Upload your files to Flussonic server and manage the order of your new live channel with txt live with an easy syntax (m3u).

Created live stream can be played with any supported protocol: HLS, DASH, RTMP, UDP.
