It does cast but the Lag makes it unusable and it is buggy as it will also disconnect all the time and you also get no sound i know from the quest app that the feature is still in beta so it still being work on or , is there any tips on how resolve this ?

I was able to cast with BeatSaber until about a week ago, but suddenly it stopped.
The music in the game was not recorded, so I think there were no rights issues.
Why was casting suddenly banned?

I tried to stream to FB with beat saber but it says content cannot be streamed when I enter beat saber. Aug 2019.

Here's how to cast everything on the Quest (unknown sources, protected apps, EVERYTHING): https://www.youtube.com/watch?v=0WbRIWfaClE

It is something the devs have to Opt-In to but in the latest Beat Saber update they have enabled it.

It now works with the latest update.

I agree with Brendan. As a developer, it's almost crucial to be able to cast in order to show co-workers issues, or results.

I want to be able to cast 'unknown sources' -- a lot of development work could benefit from seeing what the vr participant is looking at

Being able to cast to Apple TV using AirPlay would also be a nice addition

It works. I am able to cast Beat Saber to my phone. I then cast my phone to my LG TV.

I'd love to see improvement in this space, hassle free casting to computer and TV screens is a big deal for making the Quest a fun social experience.

Beat Saber and Star Wars refused to cast for me; I was able to cast Superhot and VR Chat. IDK if it's a device overhead limitation or just copyright issues.. Either way, that was disappointing.

I know it's Beta for now, but please fix this and allow to cast every experience.
