cameraController

Global hotkeys for controlling camera exposure on Windows (DirectShow) and Linux (v4l2).

Usage

cargo run -- list
cargo run -- keycodes
cargo run -- config path/to/config.toml
cargo run -- wizard path/to/config.toml

• list: list video input devices detected by the platform backend.
• keycodes: print key/button codes as you press them.
• config: Load the config, and listen for key presses to trigger camera controls.
• wizard: interactively add a binding to a config file.

Config format

[[bindings]]
key = "CTRL_L+SHIFT_L+KeyE"
device = "Logitech"
control = "Exposure"
mode = "INCREMENT"

[[bindings]]
key = "ALT+KeyA"
device = "Logitech"
control = "Exposure"
mode = "AUTO"

[[bindings]]
key = "ALT+KeyS"
device = "Logitech"
control = "Exposure"
mode = { SET = 120 }

Notes:

• Use keycodes to discover the exact key strings, or just use the wizard.
• mode supports AUTO, INCREMENT, DECREMENT, or SET.
  • AUTO: Put the exposure meter in auto mode.
  • INCREMENT: Increase the exposure by 1.
  • DECREMENT: Decrease the exposure by 1.
  • SET: Set the exposure to the given value.

Platform notes

• Linux: requires v4l2 and access to /dev/video*.
• Windows: uses DirectShow/Media Foundation to access camera controls.
