Feature

The default feature includes nothing. Anything starting with input-* is a feature that enables the specific backend.

input-* features:

input-v4l: Enables the Video4Linux backend (linux)
input-uvc: Enables the libuvc backend (cross-platform)

Conversely, anything that starts with output-* controls a feature that controls the output of something (usually a frame from the camera)

output-* features:

output-wgpu: Copies a frame directly into a wgpu texture.

You many want to pick and choose to reduce bloat.
