How to connect Android MediaCodec Surface to Vulkan

I have a pretty good understanding of decoding with Android MediaCodec and feeding YUV through a Surface into an OpenGL texture. I would like to do something similar with Vulkan. However I have not been successful in finding any documentation or sample code.

My question is: how would I wire up the following pipeline?

MediaCodec Video Decoder ⇨ Surface ⇨ texture ⇨ Vulkan

Details

Video decoder is configured using MediaCodec#configure
Surface is an Android Surface (link to API, link to arch.)

OpenGL Comparison

For comparison, in OpenGL case an Android Surface is constructed and used like so

 textureId = glGenTextures( &textureId )
 surface = new Surface( new SurfaceTexture( textureId ) )
 mediaCodec.configure( surface )

Solution

This is currently not possible, as there is no way to import memory objects from outside Vulkan, or any SDK Vulkan object that can export a Surface. Take a look at VK_KHX_external_memory and related extensions for how parts of this might work in the future.

EDIT 2018-05-23: This is now possible using the VK_ANDROID_external_memory_android_hardware_buffer extension and the extensions it depends on. You can use AImageReader_newWithUsage() to create an AImageReader compatible with GPU sampling. Get the ANativeWindow from that AImageReader and use it as the AMediaCodec's output surface. Then for each image you receive, get the AHardwareBuffer and import that into a VkDeviceMemory/VkImage pair using the extension.
