     * 30 fps when the player doesn't expose one (e.g. progressive sources).

     * Only supported for VOD: on live streams `timeShift` is measured against the constantly
     * advancing live edge, and `getTimeShift()` is not a stable reference while paused, so a
     * sub-frame step gets swamped by the edge movement and the position drifts forward instead
     * of stepping. Live frame stepping needs absolute-time seeking on the player side.
