I'm in a project in which we have to create an archive entirely in C++ for storing and loading live video streams from many cameras at once. It should run on Windows and the UNIX-systems. My question is: What is the best way to store an unknown number of live streams and load a single video when a module (e.g. GUI or Middleware) requests it? I think the tricky part is that there could be ANY amount of video streams incoming as an input. I'm also not very informed how a single video is saved and loaded, so I can't even imagine grasping the concept of saving many videos at once.
