Patch 4 enables visualization via cam.\n\nThe main changes in v2 are that the direction field in controls\ndefinitions yaml files are now required, and the code has been cleaned\nup to take advantage of Flags.\n\nv3 expands the v4l2 and local id control serializers so that we can\nremove the default bidirectional parameter from ControlId and Control\nconstructors.\n\nPaul Elder (4):\n libcamera: controls: Populate direction field in control definitions\n utils: codegen: controls.py: Parse direction information\n libcamera: controls: Add support for querying direction information\n apps: cam: Print control direction information\n\n include/libcamera/controls.h | 19 ++++++++++--\n include/libcamera/ipa/ipa_controls.h | 3 +-\n src/apps/cam/camera_session.cpp | 10 +++++--\n src/libcamera/control_ids.cpp.in | 4 +--\n src/libcamera/control_ids_core.yaml | 44 +++++++++++++++++++++++++++\n src/libcamera/control_ids_draft.yaml | 15 ++++++++++\n src/libcamera/control_ids_rpi.yaml | 3 ++\n src/libcamera/control_serializer.cpp | 11 ++++++-\n src/libcamera/controls.cpp | 45 ++++++++++++++++++++++++++--\n src/libcamera/v4l2_device.cpp | 10 ++++++-\n src/py/libcamera/gen-py-controls.py | 2 +-\n utils/codegen/controls.py | 24 ++++++++++++++-\n utils/codegen/gen-controls.py | 2 +-\n utils/codegen/gen-gst-controls.py | 2 +-\n 14 files changed, 178 insertions(+), 16 deletions(-)"}
