Modules

Raw access to each of Nokhwa’s backends.

Camera	The main `Camera` struct. This is the struct that abstracts over all the backends, providing a simplified interface for use. For more details, please refer to `CaptureBackendTrait`
CameraFormat	This is a convenience struct that holds all information about the format of a webcam stream. It consists of a `Resolution`, `FrameFormat`, and a framerate(u8).
CameraInfo	Information about a Camera e.g. its name. `description` amd `misc` may contain backend-specific information. `index` is a camera’s index given to it by (usually) the OS usually in the order it is known to the system.
Resolution	Describes a Resolution. This struct consists of a Width and a Height value (x,y). Note: the `Ord` implementation of this struct is flipped from highest to lowest.

CaptureAPIBackend	The list of known capture backends to the library. Note: Only V4L2 and UVC (and by extension AUTO) is implemented so far.
FrameFormat	Describes a frame format (i.e. how the bytes themselves are encoded). Often called `FourCC` YUYV is a mathematical color space. You can read more here. MJPEG is a motion-jpeg compressed frame, it allows for high frame rates.
NokhwaError	All errors in Nokhwa.

CaptureBackendTrait	This trait is for any backend that allows you to grab and take frames from a camera. Many of the backends are blocking, if the camera is occupied the library will block while it waits for it to become availible.
VirtualBackendTrait

mjpeg_to_rgb888	Converts a MJPEG stream of u8 into a Vec of RGB888. (R,G,B,R,G,B,…)
yuyv422_to_rgb888	Converts a YUYV 4:2:2 datastream to a RGB888 Stream. For further reading
yuyv444_to_rgb888	Convert `YCbCr` 4:4:4 to a RGB888. For further reading
