<description>
A camera feed gives you access to a single physical camera attached to your device. When enabled, Godot will start capturing frames from the camera which can then be used. See also [CameraServer].
[b]Note:[/b] Many cameras will return YCbCr images which are split into two textures and need to be combined in a shader. Godot does this automatically for you if you set the environment to show the camera image in the background.

<description>
Sets the feed format parameters for the given index in the [member formats] array. Returns [code]true[/code] on success. By default YUYV encoded stream is transformed to FEED_RGB. YUYV encoded stream output format can be changed with [param parameters].output value:
[code]separate[/code] will result in FEED_YCBCR_SEP
[code]grayscale[/code] will result in desaturated FEED_RGB
[code]copy[/code] will result in FEED_YCBCR
