Video play using rest-api

Hello All,

Suppose we have a video file checked into Cuba Application. Its more of a service video. Technician is using a mobile app to view this video.

  1. What is the best way to stream the video to technician?
  2. What if multiple techs are trying to access the same video?
  3. Are there any recommended video format (also audio) which is better for such streaming activities?
  4. If its large video, can we support playing the video from where they left off?

Thanks,
Prashanth
