  52. createInnerAudioContext()是audio组件的内部实现,不能熄屏播放、不能后台播放、不能倍速播放。
  53. getBackgroundAudioManager() 可以熄屏播放、后台播放,不能倍速播放。缺点是响应速度很慢,无法实现精细、及时的进度控制,而且可能被别的程序占用。
  54. 因此这里只能用video来实现,video能倍速播放,不能熄屏播放、不能后台播放。而且避免了用createInnerAudioContext()实现的跳转到别的页面,还在播放的问题
  55. 因此应用程序可以在需要后台播放的时候(需要用户操作触发),再暂停这个控件的播放,然后自己用getBackgroundAudioManager实现后台播放
