Possibly this requires importVideoFrame which didn't ship with the base WebGPU release, but should be coming soon. I think you still need the flag that page says.

With stable Chrome I see:

TypeError: Failed to execute 'importExternalTexture' on 'GPUDevice': VideoFrame isn't supported for importExternalTexture. This feature requires the WebGPUWebCodecs origin trial or --enable-webgpu-developer-features

With Canary, the video plays back as expected.

The specific error message given indicates that the VideoFrame was closed. It's possible that there is a timing issue with the sample or Chrome's WebGPU implementation, but more information is required to reproduce it.

If you believe there is a Chrome issue with importing VideoFrames, please file a bug at https://bugs.chromium.org/p/chromium/issues/entry.

Closing, as this appears to be an implementation bug. Please reopen or comment if that's not the case.
