  - `input-uvc`: Enables the `libuvc` backend. (cross-platform, libuvc statically-linked)
  - `input-opencv`: Enables the `opencv` backend. (cross-platform) 
  - `input-ipcam`: Enables the use of IP Cameras, please see the `NetworkCamera` struct. Note that this relies on `opencv`, so it will automatically enable the `input-opencv` feature.
