Android 将Surface附加到MediaCodec（NDK）会为GrallocMapperPasstThrough:缓冲区描述符提供无效的使用位0x2000

如果我在

AMediaCodec\u configure

中取下

format.get（）

并将

nullptr

放入其中，我不会得到

W/grallocmappersthrough:buffer描述符，其中包含无效使用位0x2000

错误，，因此问题肯定出在

javaSurface

中

我试图使

javaSurface

成为一个全局参考：

但我仍然得到了错误

到达

MediaCodecodeDecoder

构造函数的曲面是从连接到屏幕的

SurfaceTexture

创建的：

曲面曲面曲面=新曲面（SurfaceTexture）

正如您从输出中看到的，解码工作正常，因为它检测到我添加的2个流的宽度和高度

ps：请注意，我调用的queueInputBuffer的presentationTimeoutUS等于10000，因为我不知道放在那里的是什么：但我不认为这是一个问题
