+### WebGPU ### {#videoframe-webgpu}
+
+WebCodecs extends [[WebGPU]] to allow importing {{VideoFrame}} objects via
+{{GPUDevice/importExternalTexture()}}, producing opaque {{GPUExternalTexture}}
+objects, which can be read from WebGPU shaders.
+The definition of the {{GPUExternalTextureDescriptor/source}} member of
+{{GPUExternalTextureDescriptor}} is modified to allow {{VideoFrame}}:
+
+<xmp class='idl'>
+partial dictionary GPUExternalTextureDescriptor {
+    required (HTMLVideoElement or VideoFrame) source;
+};
+</xmp>
+
+The lifetime of such a {{GPUExternalTexture}} object is implicitly tied to the
+lifetime of the source {{VideoFrame}} object.
+When the {{VideoFrame}} is [=Close VideoFrame|closed=]
+(e.g. via {{VideoFrame/close()}} or
+[[#videoframe-transfer-serialization|transferring the VideoFrame]]),
+the {{GPUExternalTexture}} is *destroyed*, so no further operations
+using it can be issued.
