     * platforms or browsers, it can still change. It is therefore unreliable to just check #isLive and this detector
     * should be used as a workaround instead.

     * Additionally starting with player v8.19.0 we have the use-case that a live stream changes into a vod.

     * Known cases:
     *
     * - HLS VOD on Android 4.3
     * Video duration is initially 'Infinity' and only gets available after playback starts, so streams are wrongly
     * reported as 'live' before playback (the live-check in the player checks for infinite duration).

     * @deprecated since UI v3.9.0 in combination with player v8.19.0 use PlayerEvent.DurationChanged instead
