在我的实现中，我使用MediaCodec解码器逐帧顺序解码视频，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，第四个解码器将不会正常工作，例如当outputFormat改变时，它会为编解码器返回错误的颜色格式而前三个解码器正常工作。 我知道这主要取决于硬件，但任何想法都会特别受到与MediaPlayer关系的影响。
p.s：在开始解码之前，我会释放并清理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，或者如果我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的预期颜色格式为“QOMX_COLOR_FORMATYUV420PackedSemiPlanar32m”。
