How to programmatically detect video track quality changes on Android

This article describes how you can use the VideoTrack API, a sub-API of the MediaTrack API, to detect video track quality changes. Implementing this functionality is a common use-case for developers who want to build their own UI to visualize the video track quality that is currently active.

Usage​

Listen for the ACTIVEQUALITYCHANGEDEVENT event of a MediaTrack.

// detect video tracks being added to the player
player.videoTracks.addEventListener(VideoTrackListEventTypes.ADDTRACK) { addTrackEvent ->
    // detect quality changes of a track
    addTrackEvent.track.addEventListener(VideoTrackEventTypes.ACTIVEQUALITYCHANGEDEVENT) { event ->
        println("activequalitychanged event detected! ${event.quality}")
    }
}
