The GPUExternalTexture interface of the WebGPU API represents a wrapper object containing an HTMLVideoElement snapshot that can be used as a texture in GPU rendering operations.

A GPUExternalTexture object instance is created using GPUDevice.importExternalTexture().

Instance properties

label: A string providing a label that can be used to identify the object, for example in GPUError messages or console warnings.

Examples

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,
      }),
    },
  ],
});
// …
