Continuous looping video server-side?

I have a website. I want to create a webpage with the following behavior:

The web server should continuously loop a very long, pre-recorded video file (1+ hour).

Whenever a client accesses the webpage, the video in question starts streaming to the client at whatever timecode it is currently at server-side.

I do NOT want the client to be able to interact with the video in any way (i.e. pause, scan forward/backward, etc.). The client should only ever be able to see/hear whatever part of the video is currently playing server-side.

How can I accomplish this?
