I think there are several "features" hidden in what you describe, all of
which have (I think) a spec that currently addresses them:
* high quality video streams are available via constraints on
getUserMedia (although this is just starting to get implemented)

* the viewfinder use cases with additional controls on the camera (incl.
autofocus, exposure, preview stream) is what Image Capture is supposed
to address http://gmandyam.github.io/image-capture/ ; I think Firefox
has an early/incomplete implementation of that spec

The latter would definitely deserve to be described as a separate
feature in the repo; pull requests welcomed :)
