如果想在一整个视频里添加字幕和音频，但是视频包含了多个场景
目前我看只有场景里可以增加字幕元素，但是creator无法增加字幕

音频支持，字幕暂时不支持全局，后续可添加

// 1. 添加全局背景音
creator.addAudio('../audio/bg.mp3');  // 俩种配置方式
creator.addAudio({ loop: false, path: ... , volume:1.5});
// 2. 为每个场景添加单独音乐
scene.addAudio('../audio/bg.mp3');  // 俩种配置方式
scene.addAudio({ loop: false,path: ... , start: 20, volume:"20dB"});

// volume 音量调整参数
// 0.5:音量减半  1.5:音量为原来的150% 20dB:增加10分贝 -20dB:减小20分贝
