In the WebGPU samples Video Uploading sample, a GPUExternalTexture object (created via a GPUDevice.importExternalTexture() call) is used as the value of a bind group entry resource, specified when creating a GPUBindGroup via a GPUDevice.createBindGroup() call:

// …
const uniformBindGroup = device.createBindGroup({
  layout: pipeline.getBindGroupLayout(0),
  entries: [
    {
      binding: 1,
      resource: sampler,
    },
    {
      binding: 2,
      resource: device.importExternalTexture({
        source: video,
