iOS App Connects but won't show previews or take photos

[DishItDash]

It seems that with the introduction of LibCamera as the default library in Bullseye, the python script doesn't trigger the correct commands In the iOS app I am able to successfully connect to the raspberry pi, but no image is visible on screen. Here is what I'm seeing, even after attempting to manually install PiCam and following all of the steps in the ReadMe:

Thanks @DishItDash for pointing this out. Looks like a straightforward fix as it's a new library (Libcamera) as opposed to any changes in the underlying OS itself - so will add a new script that allows for that to be used. Not sure how this affects things like the Image FX but will see what I can do in the next couple of days.

Have you tried the PiCamera version of the script in the repo? Or does it seem to have a dependency on using the raspistill/raspivid libraries too? I'll check this out when I put a new build of Raspberry Pi OS in one of my test cameras.

Thank you for your swift response! I have basically no knowledge of programming/python, so I am actually hiring a tutor to show me how I could alter BerryCam myself as a learning goal. As I had mentioned to you on Instagram, this will be for taking pictures through my telescope. I really appreciate your time and effort, and am so excited to have come across your application. Earlier this year I tried to set up something similar, but I didn't get any usable results besides the moon since the HQ Camera sensor is so small. I do have a focal reducer that makes taking pictures with the telescope more manageable, but I'll be very curious to see if having the detailed control of BerryCam will make it a winner!

Did I mention the fix was gonna be easy? Well in some respects, getting Libcamera to talk to Berrycam is straightforward. There are some issues with the extended functionality which is going to take a bit of time to sort out, mainly around exif tagging, image FX and annotations.

The short term fix is to continue to use Raspberry Pi OS Buster until a fix can be formulated that replicates all of the functionality of Raspistill and PiCamera. I will also try to simplify the deployment process across OSes and Pi versions, but this needs a bit of time and there's only one of me to do that at the moment.

I hope this isn't too much of an issue. If you use one of the later builds of Raspberry Pi OS 10 (pre October 2021) this should allow you to install and get up and running without too many issues.
