I have a custom Control\n class to experiment with but that is not utilsed by this series.\n I'm not sure how I'd change the iterators to use this anyway yet.\n\n - This series does not aim to represent MetaData as such yet. That might be\n similar and might be possible to use a 'ControlList' but it's not clear yet.\n\n - As yet there is not a facility to obtain a list of all controls from the\n V4L2 layer, and as such I have not yet implemented any means of finding\n a complete set of controls aavilable to a particular Camera.\n\n \n \nKieran Bingham (9):\n libcamera: Value: Provide abstract value class\n libcamera: test: Add Value tests\n libcamera: controls: Introduce Control structures\n libcamera: test: Add ControlInfo tests\n libcamera: Implement a ControlList\n libcamera: request: Add a ControlList\n libcamera: test: Add ControlList tests\n [PoC] UVCPipelineHandler: Set Controls\n [PoC] QCam: Control demo: A SineWave Brightness\n\n include/libcamera/controls.h | 99 ++++++++++\n include/libcamera/meson.build | 2 +\n include/libcamera/request.h | 3 +\n include/libcamera/value.h | 63 ++++++\n src/libcamera/controls.cpp | 288 ++++++++++++++++++++++++++++\n src/libcamera/meson.build | 2 +\n src/libcamera/pipeline/uvcvideo.cpp | 43 ++++-\n src/libcamera/request.cpp | 10 +\n src/libcamera/value.cpp | 226 ++++++++++++++++++++++\n src/qcam/main_window.cpp | 16 ++\n test/controls.cpp | 139 ++++++++++++++\n test/meson.build | 2 +\n test/value.cpp | 82 ++++++++\n 13 files changed, 974 insertions(+), 1 deletion(-)\n create mode 100644 include/libcamera/controls.h\n create mode 100644 include/libcamera/value.h\n create mode 100644 src/libcamera/controls.cpp\n create mode 100644 src/libcamera/value.cpp\n create mode 100644 test/controls.cpp\n create mode 100644 test/value.cpp" }
