Zoomies

Super simple Rust/Gtk GUI to control the Zoom level on my Logitech BRIO camera.

This can be done from the command line (during use of the camera by another app) with something like the following video4linux command:

v4l2-ctl -d /dev/video2 --set-ctrl=zoom_absolute=150

The GUI tool will allow the appropriate zoom level to be selected with a scrollbar.

Clang must be installed (on Ubuntu, apt install clang) so that the Rust V4L library dependency can compile. Failure to do so will result in the following error message:

error: failed to run custom build command for `v4l-sys v0.2.0`

Notes

• On Ubuntu the video4linux v4l2-ctl command comes from the v4l-utils package.

TODO

• Make error handling nicer - all errors are treated as std::io::Error at the moment!
• Make it prettier (how does Gtk's CSS stuff work‽)
• Allow for keyboard editing of the zoom level
• Allow for multiple cameras
