I have built libcamera now myself, but I am still having same issues, I might need to build kstars as well as my version is missing a lot of stuff, including buttons :D This might finally force me to go to Stellarmate :D But we should make it stable on RPi OS as well.

I found this forums.raspberrypi.com/viewtopic.php?t=315490. It seams that is related to our problem.
Therefore if the FrameBufferAllocator is not deleted before deleting the CameraManager, the Camera object will still exist hence triggering the /dev/media warnings.
By taking another look at the Stop, Teardown and Close routines in libcamera-apps/libcamera_app.hpp and ensuring that I delete the FrameBufferAllocator I have managed to get rid of the /dev/media errors (at least for now).

I modified detectCameras() like this:
void INDILibCamera::detectCameras()
{
    std::unique_ptr<LibcameraApp::CameraManager> cameraManager(new LibcameraApp::CameraManager());
    cameraManager->start();    
    auto cameras = cameraManager->cameras();
    // Do not show USB webcams as these are not supported in libcamera-apps!
    auto rem = std::remove_if(cameras.begin(), cameras.end(),
                              [](auto & cam)
    {
        return cam->id().find("/usb") != std::string::npos;
    });
    cameras.erase(rem, cameras.end());
 
    if (cameras.size() == 0)
    {
        LOG_ERROR("No cameras detected.");
        return;
    }
 
    CameraSP.resize(cameras.size());
    for (size_t i = 0; i < cameras.size(); i++)
        CameraSP[i].fill(cameras[i]->id().c_str(), cameras[i]->id().c_str(), ISS_OFF);
 
    int onIndex = -1;
    if (IUGetConfigOnSwitchIndex(getDeviceName(), "CAMERAS", &onIndex) == 0)
        CameraSP[onIndex].setState(ISS_ON);
    else
        CameraSP[0].setState(ISS_ON);
 
    cameraManager->stop();
    cameraManager.release(); // I added this line
    cameraManager.reset();
}

and now

I did. This is compile output from QT Creator:

Are locations correct?

Never mind, I corected problem with:
LD_LIBRARY_PATH=/usr/local/lib

And error went away. Not sure if it's the right thing to do though? Why would library output location change after updating to new version?

After commenting out the cameraManager->reset(), mine fails with the option parsing in StillOptions Option::Parse(). Where does this live anyway? The Option class just has this as virtual?

//if (Options::Parse(argc, argv) == false)
// return false;

Commenting this goes a bit further, but unsurprisingly croaks with:

ERROR 21.847219 sec : Error opening camera: bad thumbnail parameters

A workflow that halfway works for me is having two windows, in the one I recompile and start indi:

pi@astrocam:~/astro/indi-3rdparty/build/indi-libcamera $ make && indiserver -v `pwd`/indi_libcamera_ccd

and in the other I do:

pi@astrocam:~/.indi/logs/2022-11-26/indi_libcamera_ccd $ rm *.log && indi_setprop LibCamera.LOG_OUTPUT.FILE_DEBUG=On && indi_setprop LibCamera.CONNECTION.CONNECT=On && cat *.log

which deletes the previous log, sets logging to file to on and connects.

Faking the still options gives:

Are there any instructions on installing QTCreator on the pi? I only found pretty involved stuff that requires recompiles and cross compiles?

Just for your info it is very sluggish and freezing on 4b 1gb, while it works well on 8gb version.

I run QT Creator on Raspberry Pi 4B 4GB and it works fine.

Finally I have managed to make some progress. Method detectCameras() no longer crashes. And driver starts in EKOS (see attached image).

More here: github.com/sajmons/indi-3rdparty/commit/...7f51c85f3f06789f2c4e.

OUTTA, Jasem, what would be next step? Probably fill in more information about camera capabilities, so that more buttons in EKOS gets enabled?

I wonder if we'd be better off creating a static CameraManager instead of this create/destroy dance. We'd probably have to pull more bits of the libcamera-apps code in rather than linking to it, but that might not be such a bad thing sone those seem to be demos that might be unstable and/or depend on Raspberry Pi specific components. I'll start looking into what that would look like.
