Question

我有一个带视频播放器的应用程序。我实现了一种方法，用于存储视频中的当前位置，以便下次用户播放相同的视频时，从用户离开的位置播放。但是，我无法从剩下的位置加载视频。 log cat连续显示此错误

这是我播放视频的代码。任何人都可以在这里指导我为什么我收到此错误。谢谢..这是代码

来自文档：

尽管异步seekTo(int)调用以正确的方式返回，但实际的搜索操作可能需要一段时间才能完成，尤其是对于流式传输的音频/视频。当实际搜索操作完成时，如果事先通过OnSeekComplete.onSeekComplete()注册了OnSeekCompleteListener，则内部播放器引擎会调用提供的用户setOnSeekCompleteListener(OnSeekCompleteListener)。

您可能收到此错误的原因是因为媒体播放器缓慢搜索，因此当您开始播放视频时，它并未进行搜索。因此它会读取损坏的缓冲区
