Dear Media Working Group,

The GPU for the Web Working Group has made significant progress on first 
versions of the WebGPU and WebGPU Shading Language (WGSL) 
specifications. The group is now firming up the specifications with a 
view to requesting publication as Candidate Recommendations later this 

The Working Group would like to invite you to review the latest versions 
of the specifications:

- WebGPU: https://www.w3.org/TR/webgpu/
- WGSL: https://www.w3.org/TR/WGSL/

Working drafts are updated on a continuous basis but there should be no 
more breaking changes at this stage. Feel free to review dated versions 
of the specifications to avoid looking at a moving target.

It is anticipated that media applications may want to use WebGPU in 
combination with WebCodecs when it becomes more broadly available to 
create efficient processing pipelines of audio/video frames. Further 
improvements to import mechanisms are being considered for a future 
revision of the WebGPU spec (e.g. see [1]).

The Working Group plans to request publication as Candidate 
Recommendations no sooner than 15 October 2022 and welcomes comments 
prior to that date, preferably through issues on the group's GitHub
