The player plays only from one instance.

Hi all.

The Peertube provides functionality for playing video from multiple instances (it is not a torrent and it is not P2P). Some instances is configured so, that they have a redundancy strategy thats allow store copy of videos from other instances in a federation.

This is the main feature that allows to reduce the load on the instance for recently-added and most-viewed videos.

For example: https://peertube.ignifi.me/w/mHKbbkrsKkFTnjMd4WRc8R

Player shows 3 peers:

DevTools:

So, the Peertube player is downloading streams from 3 instances in a federation. This described also here.

I understand that this is not a high priority issue, but it can be a big problem for some instances if a lot of people use the application and use only one instance instead of federation. The instance will overloaded.

I've gone very deep into how it works, but I can't get Exoplayer to work with multiple sources. Thanks!

Reproduce the linked PeerTube example and compare its player behavior with the DevTools evidence and the linked instance-redundancy documentation. The issue names ExoPlayer but no repository file or test; first identify the extractor or playback entry point involved, then determine what evidence would show streams are being obtained from multiple federated instances.
