Send timed metadata to controller

[icbaker]

Arbitrary Metadata.Entry objects are not sent from MediaSession to MediaController, so what you're observing is expected.

@marcbaechinger might have thoughts on the best way to send time-accurate info from a session to a controller.

@thetwom Can you give some info about what these timed events that you want to send represent? It might help guide us towards a solution.

Thanks a lot for taking the time and answering my question. Good to know, that things are working as expected (even though it would have been nice for me if it worked :-).

I guess my case is rather exotic, so I don't know if I want to take your time for finding a solution. Still, I will quickly give a description:

My player is not playing regular media, but it is a metronome, which plays sounds at regular time intervals (like a "clicking" sound 4 times a second). When the app is at the foregound, visual feedback for the "clicks" is required. The player implemention is able to emit the corresponding information shortly before the click starts and I am looking for a way to bring this information to the UI.

Timed metadata seemed like something which would exactly fit the needs, but besides of not being transferred to the controller, I am unsure, if it would able to deliver information reliable within a small enough latency (say 0.1s).
