VideoPlayer entity in Horizon Worlds

They are different types of studios 1p, 2p, & 3p. 1p may have features that 2p and 3p don't have access to and 2p may have features that 3p don't have access to. I couldn't find any official definition/doc for 1p, 2p, 3p for Meta. For an example (Sony) does it this way:

First-party: A game published and fully funded by Sony. Usually owns the IP.

Second-party: A game published by Sony with partial or full funding coming from an external company. Usually doesn't own the IP.

Partner title: A game published and developed by an external company launching first or earlier on PlayStation platforms.

Third-party: A game published and fully funded by an external company.

This is just an example of how Sony does this. Amazon has a similar system but for sellers and I am sure most platforms have a similar system tailored to whatever their platform is for. Besides the feature access I am not certain what else it all covers for Meta. I also do not know which features they would have access to. Nor do I know how a 3p would become 1p or 2p.

In Unity? Yes, but you can't use Unity for Horizon Worlds.
