With this patch auto-focus can\nbe enabled for cameras that support it. By default it is disabled, which\nmeans default behaviour remains unchanged. For cameras that do not\nsupport auto-focus, an error message shows up if auto-focus is enabled.\n\nThis was tested on cameras that do not support auto-focus (e.g. PiCam2)\nand was tested on a camera that does support auto-focus (PiCam3) by\nsetting it to AfModeContinous, observing auto-focus, and by setting it\nto AfModeManual or by not setting the option, both resulting in\nauto-focus being disabled.\n\nBug: https://bugs.libcamera.org/show_bug.cgi?id=188.\n\nSigned-off-by: Cedric Nugteren \n---\nChanges since v1:\n- Now re-using the GParamSpec variables instead of re-creating.\n- Use bool instead of gboolean for enable_auto_focus.\n- Remove changes from the reconfigure_element functions.\n\nChanges since v2:\n- Fix a typo in the commit message (remove 'it').\n- Fix the link to the actual bug.\n- Apply the style suggestions of utils/checkstyle.py.\n- Start the commit message with 'gstreamer:'.\n- Change the boolean to a 3-option AfMode enum and change variable\n names and strings accordingly.\n\n---\n src/gstreamer/gstlibcameraprovider.cpp | 14 ++++++++++++\n src/gstreamer/gstlibcamerasrc.cpp | 30 ++++++++++++++++++++++++-\n src/gstreamer/gstlibcamerasrc.h | 31
