Hi,

I'm trying to implent a code that uses libcamera-apps librairies to control a Arducam 64MP. I can't get the autofocus to work like your libcamera-still does. I applied all the patches that I found in this repo (under realese). Could you please provide the source code of your libcamera-apps (installed through the script) or a patch to apply to the base raspberry/libcamera-apps.

Thanks

I've actually found the solution to my problem. I didn't set the auto focus mode to auto before sending an auto focus trigger. This can be achieved using the method SetControls() form libcamera-apps lib. 

        libcamera::ControlList controls;
        controls.set(libcamera::controls::AfMode, libcamera::controls::AfModeAuto);
        SetControls(controls);

Then the auto focus can be triggered using the following:

        libcamera::ControlList controls;
        controls.set(libcamera::controls::AfTrigger, libcamera::controls::AfTriggerStart);
        SetControls(controls);

All the available controls can be found https://github.com/raspberrypi/libcamera/blob/main/src/libcamera/control_ids.yaml
