"content": "Hello,\n this series adds an initial implementation of an Android compatbile HAL\nmodule that wraps libcamera.\n\nThe series adds by exposing the Camera state to have it accessible to the HAL\nand continues tweaking the build system to add a condtional 'android' option.\n\nPatches 3 and 4 import from Chrome OS the Android camera HALv3 headers and the\nAndroid metadata library, which is linked against then newly created HAL.\n\nThe last patch finally implements the HAL module itself, split between an HAL\nmodule that is used by the Android/Cros camera stack to load the .so file and\nsetup callbacks and a CameraModule and CameraProxy modules, that realize the\nAndroid camera HALv3 APIs.\n\nThe HAL implementation is still immature and incomplete, as it provides only\nbasic functionalities, but it is enough to test capture of a single video stream\nusing Chromium OS camera applications.\n\nThanks\n j\n\nJacopo Mondi (5):\n libcamera: camera: Make camera state
