[libcamera-devel,v3,00/14] libcamera Controls

1542 mbox series

Hello,

Here's the third version of the libcamera controls series, taken over
from Kieran (with his consent and help).

The main API changes since v2 are

- The Value class has been renamed to ControlValue
- The ControlList class is now indexed by ControlInfo pointer instead of
  instance
- The ControlList class is constructed for a camera, and looks up
  ControlInfo from that camera
- The V4L2ControlInfo class now exposes the min and max values
- The Camera has a new method to expose all the controls it supports

Notable changes are also file renames (control_definitions.h ->
control_ids.h and control_definitions.cpp -> control_types.cpp), dynamic
query of supported controls in the UVC pipeline handler, control support
in the VIMC pipeline handler and handling of control minimum/maximum
values in the qcam proof-of-concept patch.

Todo items include

- Better documentation for the initial controls
- Integer type handling for ControlValue (see patch 04/14)
