    public void onClick(View v) {
        if (playerView.getPlayer() != null) {
            boolean isMuted = playerView.getPlayer().getVolume() == 0;
            playerView.getPlayer().setVolume(isMuted ? 1 : 0);
            muteButton.setImageResource(isMuted ? R.drawable.ic_volume_on : R.drawable.ic_volume_off);
