[libcamera-devel] [PATCH 5/5] cam: Use script parser to set controls

[Jacopo Mondi]

Add to the CameraSession class a script parser instance, created
conditionally to the OptCaptureScript option.

If the script parser has been created, use it at queueRequest time to
retrieve the list of controls that has to be associated with a Request,
and populate Request::controls() with it before queueing it to the
Camera.
