I need to add this file ( link )
E Play it so it looks more like this /
This file is part of an MPEG-DASH package. Several market players reproduce this, but you need the manifest file for this, as well as all parts that for a 2 minute video can be more than 200 files. Usually this file is provided encrypted and the browser obtains the decryption key (DRM) and works reliably with the server.
If files are encrypted, it is virtually impossible to play without the key that is dynamically provided during playback with the data provider's player.
An example of who uses this is Netflix.
This is a company that works with this type of player link
