android - TextureView 中的 MediaPlayer 未按预期工作

Question

我在 TextureView 中放入了一个 MediaPlayer，它本身位于 ListView 中。

昨天，MediaPlayer 按预期使用了一个测试 .mp4 剪辑。
今天，MediaPlayer 尝试做某种 FFmpeg 提取器，但我一直无法找到任何相关信息。

这是堆栈跟踪:

我真的一点也不明白是什么导致了所有这些错误，为什么视频文件无法播放？
如果有人能够提供帮助，我将不胜感激!

我正在使用 Genymotion 模拟器 - Google Nexus 4 - API 21

非常感谢!

这是模拟器的问题。在 Android 手机上测试并运行良好，重置 Genymotion 模拟器并创建一个新的，它继续正常运行。
