API/MistVideoObject: How to know which track is playing (and when to check)?

[labor4]

Hi

Sorry to bother, but I think I got lost in the MistVideoObject! 😀
No seriously, I'd be greatful for a hint:

I'm trying to query what tracks are currently playing.

I see that in:

...reference.info.meta.tracks

there is the whole menu.

I saw that the content of the event playerUpdate_trackChanged reveals the corresponding track id for both audio and video. But that event seems to only show up with webrtc.

Therefore question:

• Where can I read which trackid is currently selected, so I can look it up in ...reference.info.meta.tracks?
• which event certainly marks the time after which that value can be safely queried?

Thank you kindly!

Best Regards
