In order to do so, a new CameraDevice::initialize() method\nis provided, where the collection and inspection of all Camera static properties\nhappens before the CameraDevice::open() method gets called.\n\nBuilding on this foundations, patch 4 builds the image format translation\nmap and the available stream configuration map by testing a set of required\nand optional image resolutions against the wrapped libcamera::Camera instace.\nThe patch produces an android-format to libcamera-format map and a list of\navailable stream configuration items, to be reported to the Android framework\nthrough static metadata.\n\nPatch 5 makes the metadata buffer size calculation 'dynamic', by inspecting\nthe number of elements which have been collected in the stream configuration\nmap.\n\nPatch 6 and 7 make use of the information collected in patch 5 to, respectively,\nreport to the framework the available stream configuration map, and to translate\nfrom Android format to libcamera format at processCaptureRequest time.\n\nWhile I was reading the camera documentation, I spotted a rougue full stop\nin a \\return statement in documentation, and while at there I removed it.\n\n\nJacopo Mondi (8):\n android: camera_device: Provide log prefix\n android: hal_manager: Report supported API version\n android: hal_manager: Do not hardcode properties\n android: camera_device: Build stream configuration\n android: camera_device: Calculate metadata size\n android: camera_manager: Replace hardcoded stream configuration\n android: camera_device: Translate Android format\n libcamera: camera: Drop full stop from \\return\n\n src/android/camera_device.cpp | 375 ++++++++++++++++++++++++-----\n src/android/camera_device.h | 29 ++-\n src/android/camera_hal_manager.cpp | 12 +-\n src/libcamera/camera.cpp | 2 +-\n 4 files changed, 352 insertions(+), 66 deletions(-)\n\n--\n2.26.2" }
