Youtube视频无法以纵向模式播放

Question

我在我的安卓代码中使用了Youtube api，当我以纵向模式播放视频时，它会在一秒后暂停，但是当我在全屏（风景）模式下播放它时，它可以正常工作。以下是一些相关代码：

YouTubePlayerView youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player);
        youTubePlayerView.initialize(API_KEY, this);

@覆盖

public void onInitializationSuccess(Provider provider,
        YouTubePlayer player, boolean wasRestored) {

    player.setPlayerStateChangeListener(playerStateChangeListener);
    player.setPlaybackEventListener(playbackEventListener);

    //** Start buffering **//*
    if (!wasRestored) {
        player.cueVideo("video ID");
    }

    player.getDurationMillis();
}

private PlaybackEventListener playbackEventListener = new PlaybackEventListener() {

    @Override
    public void onBuffering(boolean arg0) {

    }

    @Override
    public void onPaused() {

    }

    @Override
    public void onPlaying() {
    }

    @Override
    public void onSeekTo(int arg0) {

    }

    @Override
    public void onStopped() {
        btn.setVisibility(View.VISIBLE);
    }

};

private PlayerStateChangeListener playerStateChangeListener = new PlayerStateChangeListener() {

    @Override
    public void onAdStarted() {

    }

    @Override
    public void onError(ErrorReason arg0) {

    }

    @Override
    public void onLoaded(String arg0) {

    }

    @Override
    public void onLoading() {
    }

    @Override
    public void onVideoEnded() {

    }

    @Override
    public void onVideoStarted() {

    }
};

}
