player.controls.currentPosition 返回播放文件的当前时间位置（以秒为单位）
player.controls.currentPositionString 时间格式的字符串 "0:32"
player.currentMedia.duration 返回播放文件的总长度（以秒为单位）
player.currentMedia.durationString 时间格式的字符串 "4:34"
player.settings.volume 音量 （0-100）

player.DoPause() 暂停
player.DoStop() 停止

player.GetPosition() 返回播放文件的当前时间位置（以毫秒为单位）
player.GetPlayState() 返回播放器状态（0:停止,1:连接,2:缓冲,3:播放,4:暂停,5:寻找）
player.SetPosition(n) 时间位置跳到n的地方（n取值以毫秒为单位）
