Current stock\n implementation on CrOS is to ::exit(1) cros_camera_service \n if an open camera is unplugged. AOSP doesn't seem to handle\n this use case, maybe because it doesn't have notion of \n hot-[un]pluggable cameras? Add a \\todo on unplug handler path.\n \nChanges from v1:\n- Treat all UVC cameras as external - based off Laurent's suggestion.\n -It's difficult to know whether a UVC camera is external or internal.\n Hence, treat all UVC camereas as external by setting their\n CameraLocation property as CameraLocationExternal.\n- Use different IDs for internal and external cameras.\n -Internal camera IDs are meant to be started with 0 and\n external/removable ones from 1000. Also, support that\n if the camera has been seen in the past, reuse it's ID.\n- Few changes dealing with race conditions, locking and graceful\n handling of currently streaming camera.\n\nUmang Jain (5):\n libcamera: pipeline: uvcvideo: Treat all UVC cameras as external\n android: camera_hal_manager: Set camera module callbacks\n android: camera_device: Make CameraDevice a shared object\n android: camera_device: Add a getter to get libcamera::Camera pointer\n android: camera_hal_manager: Support camera hotplug\n\n src/android/camera3_hal.cpp | 2 +\n src/android/camera_device.cpp | 15 ++\n src/android/camera_device.h | 8 +-\n src/android/camera_hal_manager.cpp | 179 ++++++++++++++++---\n src/android/camera_hal_manager.h | 23 ++-\n src/libcamera/pipeline/uvcvideo/uvcvideo.cpp | 7 +\n 6 files changed, 209 insertions(+), 25 deletions(-)"}
