This is a flexible video player. MediaPlayer is completely separate from VideoView and can be replaced with other player kernels such as ExoPlayer and ijkPlayer. Developers can fully customize the player view, which we call the control panel. In addition, developers can use MediaPlayerManager to control playback behaviours, such as full-screen mode, small screen mode, and smart matching modes in RecyclerView.这是一个小巧灵活的视频播放器。支持全屏，小屏播放；支持重力感应；支持IjkPlayer，支持ExoPlayer；内部支持RecyclerView中播放；自定义UI ；APP内全局播放；静音；循环播放
