Yeah, there's a private webcam extension ([code](https://cs.chromium.org/chromium/src/extensions/browser/api/webcam_private/?q=extensions/browser/api/webcam_private&sq=package:chromium&dr)), essentially a JS-surfaced IDL directly touching the filesystem `/dev/videoX` to manipulate zoom, pan and tilt for certain cameras ([more code](https://cs.chromium.org/chromium/src/extensions/browser/api/webcam_private/v4l2_webcam.cc?sq=package:chromium&dr&l=18)).   The issue that prompted that commit was to avoid resetting those controls because the clients of this extension API relied on the V4L2 API persisting the configuration values.
