Having a problem capturing an image on Android 14. Tombstone looks like this:

Streaming works until trying to capture and image via MLKIT

Unfortunately an issue this is out of scope for this repo, which is just a Raspberry Pi specific fork of libcamera. I would advise to re-send this issue to the libcamera dev mailing list instead.

Thanks, I will try to raise it with libcamera itself. I'm pretty sure they will refer it back here, since it was not reported by other platforms. It specific to Raspberry Pi 4 & 5, I have same issue on various Android distro's and self built version. With self built version I compiled various source versions with the same effect. Tested on both CM4 and RPi5.
