Here is at least half of the answer for you How to implement one-to-many video streaming with minimal delay?
There, in the first answer, I gave an example of an nginx config that accepts a stream in rtmp and makes it an hls / mpeg-dash stream that site users can watch. If you change a couple of parameters, then the stream cut into pieces can be stored on the disk for an indefinitely long time.
In my case, I published a stream from a video conference from FreeSwitch, but the source of the rtmp stream could be anything.
