@dsanders11 : I have used OpenCV.JS to accomplish similar use cases, like card scanning. Please have a look at our [WebCamera](https://github.com/riju/WebCamera) project.
We did try out getting `canvasContext.getImageData` to a `SharedArrayBuffer` and used `worker.postMessage` and did the computations in the workers. It's not yet on master as the WASM (with SIMD + workers) optimizations improved the user perceived performance to an acceptable level.
@alvestrand : The [webrtc-nv-use-cases](https://w3c.github.io/webrtc-nv-use-cases/) look good and I am interested mainly in the requirement -
```
N18 The application must be able to obtain raw media
from the capture device in desired formats.
```
and what developers can do with that.
Like @dsanders11 said, it can be sub-optimal to deal with various formats a webcam can stream, maybe the [WebCodecs](https://github.com/WICG/web-codecs/blob/master/explainer.md) proposal can be of help ?
