1806659 - (webgpu-official-samples) [meta] Ensure that official WebGPU samples work (except for video import)

Status: NEW

(Core :: Graphics: WebGPU, task, P3)

Description

[Nicolas Silva [:nical]]

Meta bug to track outstanding spec compliance and stability issues preventing us from running WebGPU demos (picking Austing Eng's because I think they are to date withe the spec https://austin-eng.com/webgpu-samples)

Comment 1

[Erich Gubler [:ErichDonGubler]]

Fun fact: The link in the description now redirects to https://webgpu.github.io/webgpu-samples/.

Comment 2

[Erich Gubler [:ErichDonGubler]]

VideoFrame blocks the videoUploadingWebCodecs demo specifically.

Comment 3

[Jim Blandy :jimb]

We're not going to worry about video import for now.
