I was unable to get the Signals\nproperly connected to a lambda or a method, although connecting to a\nstatic function works. It compiles but the handler is never called, and\nmy tests seg fault at exit.\n\nAnd this needs documentation...\n\n Tomi\n\nTomi Valkeinen (7):\n py: cam.py: Fix multi camera capture without -C\n py: Add Python logging category\n py: Move ControlValue helpers to py_helpers.cpp\n py: Create PyCameraManager\n py: Add 'nonblocking' argument to get_ready_requests()\n py: New event handling\n py: cam.py: Use new events support\n\n src/py/cam/cam.py | 33 ++-\n src/py/libcamera/meson.build | 2 +\n src/py/libcamera/py_camera_manager.cpp | 393 +++++++++++++++++++++++++\n src/py/libcamera/py_camera_manager.h | 74 +++++\n src/py/libcamera/py_helpers.cpp | 98 ++++++\n src/py/libcamera/py_helpers.h | 13 +\n src/py/libcamera/py_main.cpp | 283 +++++++-----------\n src/py/libcamera/py_main.h | 12 +\n 8 files changed, 730 insertions(+), 178 deletions(-)\n create mode 100644 src/py/libcamera/py_camera_manager.cpp\n create mode 100644 src/py/libcamera/py_camera_manager.h\n create mode 100644 src/py/libcamera/py_helpers.cpp\n create mode 100644 src/py/libcamera/py_helpers.h\n create mode 100644 src/py/libcamera/py_main.h"}
