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

[Laurent Pinchart]

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)
