[BUG] 播放暂停切换时出现 I/O error

[gaoyong06]

按照，项目的defaultFijkPanelBuilder示例, 在调用播放，暂停的方法，一直在测试，所以就频繁的在点击，偶尔会出现下面的bug， 视频都很小1分钟左右.

//暂停，播放切换
void _playOrPause() {
if (_playing == true) {
player.pause();
} else {
player.start();
}
}

我也碰到这个问题。
还有播放结束后再次点击播放出现：stream 1, offset 0x13807e: partial file

我也碰到了这个异常信息,不过场景是断网后观看完缓冲数据提示的,在监听事件中即使再次调用播放方法也不能继续播放,会提示:
