Android 如何将音频YouTube和DroidPlayeRapi静音？

我想静音YouTube Android Player API的音量，我使用了YouTubePlayerFragment，当我将自定义图像视图放在上面时，它显示了我的错误`

YouTubeAndroidPlayerAPI

：YouTube视频播放停止，因为未经授权的覆盖在播放机顶部。那么我如何才能按下按钮使音频静音？有人能帮我吗

youTubePlayerSupportFragment.initialize(API_KEY, new com.google.android.youtube.player.YouTubePlayer.OnInitializedListener() {
                    @Override
                    public void onInitializationSuccess(final com.google.android.youtube.player.YouTubePlayer.Provider provider, com.google.android.youtube.player.YouTubePlayer youTubePlayer, boolean b) {
                        mTubePlayer = youTubePlayer;
                        mTubePlayer.setPlayerStyle(com.google.android.youtube.player.YouTubePlayer.PlayerStyle.MINIMAL);
                        mTubePlayer.setManageAudioFocus(true);
                        if (ytInit.size() - 1 > linearLayoutManager.findFirstVisibleItemPosition())
                            mTubePlayer.cueVideo(strings.get(linearLayoutManager.findFirstVisibleItemPosition()), ytInit.get(linearLayoutManager.findFirstVisibleItemPosition()));
                        else
                            mTubePlayer.cueVideo(strings.get(linearLayoutManager.findFirstVisibleItemPosition()));
                        new Handler().postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                if (mTubePlayer != null) {
                                    showEpisodeThumbnail.setVisibility(View.GONE);
                                    prg.setVisibility(View.GONE);
                                    mTubePlayer.play();
                                    frm.setVisibility(View.VISIBLE);
                                }
                            }
                        }, 1000);

                    }

                    @Override
                    public void onInitializationFailure(com.google.android.youtube.player.YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

                    }
                });

我得到的答案是youtube没有提供任何在API中静音音频的功能，我使用了自定义iframe播放器
