INDI LibCamera Driver

INDI LibCamera Driver was created by Jasem Mutlaq

I started work in INDI LibCamera driver. This is meant to run on Raspberry PI using Debian 11 (Bullseye).

As of 2022.08.21, the driver is just a skeleton and cannot be used for anything. Once capture works, we'll ask for feedback in this thread.

Thanks a lot! It's just what I needed. I had to install a few libs:

<code>sudo apt-get install libindi-dev libcamera-dev libcamera-apps libboost-program-options-dev</code>

Unfortunately, I get build errors complaining about "addFitsKeyWords" being unknown and I had to copy the /usr/include/libcamera/libcamera/* files to the parent dir and I actually had to compile indi from source and install to get the indilib includes correct. Otherwise it would complain about /usr/include/libindi/indipropertyswitch.h missing.

Fixing those and starting the driver works, but I can't see images and the size is 0,0, likewise the pixel size.

Any help here would be appreciated!

Hm. Reading the source of indi-libcamera doesn't show anything except a bit of options parsing? It doesn't seem to do anything?

And... actually reading the top post gives a clue that it doesn't do anything... OK, I was mislead by the post from Aaron and thought he talked about the driver, while he probably meant the all-sky thing. So never mind.

Do you have an ETA for the driver? I can see the skeleton seems to be working, so "only" hooking up the actual capture seems to be missing? Anything one can help with?

Could you mark the missing parts with a some // TODO annotations and/or maybe a high-level TODO.txt which just outlines on what's missing and how to progess?

Something like:

- add capturing in x.cpp
- add skeleton xml for options
...

Try to run this is a debugger. This is still in very early stages. See where it crashes exactly. I found libcamera to be unreliable now :(

I think I set something up incorrectly, see this

<code>astroberry@raspberrypi:~/Projects/build/ekosdebugger $ which indi_libcamera_ccd
/usr/bin/indi_libcamera_ccd
astroberry@raspberrypi:~/Projects/build/ekosdebugger $ which indiserver /usr/bin/indiserver
astroberry@raspberrypi:~/Projects/build/ekosdebugger $

When I use EKOSDEBUGGER
<code>2022-11-06T08:05:54: startup: /usr/bin/indiserver -r 0 -v indi_libcamera_ccd indi_simulator_ccd indi_simulator_focus indi_simulator_telescope

and when i run indiserver indi_libcamera_ccd from terminal I get error from post above


In my Kstars there is no Libcamera so I added it manually to code as I cannot add it to profile... any ideas?

Also can you share your
libcamera-hello --version
To eliminate discrepancy there

It's also in a few other places, dunno how relevant the .spec is:

pi@astrocam:~/astro/indi-3rdparty/indi-libcamera $ rg asi |grep indi

indi-libcamera.spec:Name: indi-asi
indi-libcamera.spec:BuildRequires: libasi
