在 Android 中将外部缓冲区导入 Vulkan 时出现问题

我正在尝试使用 Vulkan 在 Android 10 中显示图像。管道看起来像这样

MediaCodec -> ImageReader -> AHardwareBuffer（传递到 Vulkan 上下文） -> 映射到 Vulkan -> 使用 Vulkan API 显示它

在 Native CPP 层中，在 Vulkan Context 中完成以下操作以导入 hardwarebuffer：查找 AHardwareBuffer 的属性 -> 创建 VkImage ->创建设备内存（专用内存）-> 将缓冲区映射到 VkImage -> 使用 YUVSampler 进行采样

问题在于“创建设备内存”是 Vulkan 验证层显示错误的步骤。它抱怨该格式不受支持。请注意，我使用的是外部格式（SPEC 允许这样做），因此格式处理是不透明的。 这现在不起作用，我每次都只看到一个黑框。有人可以评论一下吗？我在将 AHardwareBuffer 导入 Vulkan 上下文的逻辑中缺少什么。

为什么是外部格式？好吧，因为我无法控制不同设备上解码器的输出，并且想要一些不透明的方法来处理它。

另外，我使用以下设置来创建 ImageReader

ImageReader.newInstance(1920, 1080, ImageFormat.PRIVATE, MAX_IMAGE_SIZE + 1,
    HardwareBuffer.USAGE_GPU_SAMPLED_IMAGE);

Vulkan 中的代码，从我收到 AHardwareBuffer 到验证层认为导致问题的 API，如下所示。我尝试仅将相关代码保留到此处的映射。
