2008706 - WebGPU: external textures missing on Android

Status: NEW

(Core :: Graphics: WebGPU, defect)

Description

[Jamie Nicol [:jnicol]]

This will require:

• a wgpu implementation for external textures on Vulkan/SPV
• Android video decoding using AImageReader (bug 1649110), allowing us to obtain the AHardwareBuffer containing the video data.
• Implementing a new function ExternalTextureHostSource::CreateFromAndroidHardwareBufferTextureHost() called from here.
  • Which will call in to wgpu_bindings rust code to create a wgpu::Texture from a HardwareBuffer. Perhaps some of this can be shared with the Linux implementation (bug 2008705) - creating the Vulkan texture from a HardwareBuffer will of course differ from creating one from a DMABuf, but creating the wgpu::Texture from the wgpu_hal::vulkan::Texture could be shared.
• Updating the blocklist here
