Have you looked at the reference application that is present in the
codebase 'qcam' ? There are lot of initial pointers in there, for
the things you are trying to do, I guess. <br>

<br>
The best example for 3A in libcamera is the Raspberry Pi IPA
code.<br>
<br>
Please examine:<br>
src/ipa/raspberrypi/<br>
<br>
The Raspberry Pi pipeline handler controls that IPA, so for
direction<br>
there, look at :<br>
<br>
src/libcamera/pipeline/raspberrypi/raspberrypi.cpp<br>
<br>
But perhaps you are looking for what controls are available
for<br>
applications to 'control' the 3A. A lot of that is still under<br>
development, but you should also look at :<br>
<br>
src/libcamera/control_ids.yaml<br>
<br>
Which generates docuemntation at :<br>

<br>
<br>
I see from your threads, you have been doing quite a bit of<br>
investigation over the various areas of libcamera.<br>
<br>
Perhaps could you share what you are working on with
libcamera?<br>
<br>
Are you planning to create an application using it? or do you
have<br>
devices in mind which you think libcamera should be
supporting?<br>
