在我的实现中，我使用 MediaCodec 解码器按顺序逐帧解码视频，一切正常。但是，如果在开始解码过程之前我使用 MediaPlayer 和 TextureView（我使用 GLES 渲染的扩展 TextureView）播放一些媒体，第四个解码器将无法正常运行，例如当 outputFormat 更改时，它会为编解码器返回错误的颜色格式而前三个解码器工作正常。我知道它主要取决于硬件，但任何想法都会特别感谢它与 MediaPlayer 的关系。
ps：在开始解码之前，我确实释放并清理了 MediaPlayer 实例。
编辑：
该设备是三星 Note3，我正在播放常规媒体。当它失败时，即使我等待几分钟或强制停止活动并重新运行它，除非我重新启动设备，否则行为仍然存在。您可以在以下日志中看到预期的颜色格式是“QOMX_COLOR_FORMATYUV420PackedSemiPlanar32m”。
