Error With Sensor Mode 3, RPi HQ Camera on RPi Zero 2 W

[johnson29630]

Describe the bug
Cannot select 'Sensor Mode 3' for maximum resolution for RPi HQ Camera.

To Reproduce
New installation on RPi Zero 2 W running headless. Using SSH/Putty to install and start CamUI with all dependencies. CamUI startes with no noticable issue.

• Using the web interface on a network computer/browser, switch to 'Camera' view. (camera does work)
• Can switch from Mode 1 to Mode 2 or Mode 3, no issues, camera view displays, can capture images.
• Attempted to select Mode 3 faximum resolution for RPi HQ Camera, camera window does not display live image, will not capture images. The SSH/Putty window shows debug window with 'Error saving profile: [Errno 12] Cannot allocate memory' error
• I can select Mode 0, functionality is restored.

Expected behavior
I expect to be able to use Mode 3, as well as Modes 0/1/2

Desktop (please complete the following information):

• OS: Windows 10 Pro
• Browser: Chrome
• Version 136.0.7103.114 (Official Build) (64-bit)

Additional context

RPi Zero 2 W running RPi OS (lite). Followed instructions to install CamUI and dependencies. Specificalu using RPi Zero 2 W for small size and reduced power consumption.

SSH data captured and attached. Shows all activity once CamUI was started.

Line 1: CamUI started
Line 143: select Mode 1 from web interface (started at Mode 0)
Line 164: select Mode 2 from web interface
Line 185: select Mode 3 from web interface (camera stops working)

yeah there is an issue higher resolution on older hardware... the mjpeg encoder crashes when its too much for the system.

in the branch https://github.com/monkeymademe/CamUI/tree/v2.0.1 I changed the encoder to the jpegencoder. I tested with the pi4 and v3 camera and it seems to be working ok... There is an unknown effect to performance and quality but at least its working for now.

I don't have a pizero setup for testing so if you could give it ago to see if its better?

Please remember pizero with maxed out resolution might not work so well...

@monkeymademe I've been traveling, and will test the new version as soon as I am settled in. Thanks for the response. I'm using the Pi Zero 2 W as it's a small package with the camera, and it's low power for battery use. Will update with my results!

Finally got home and and trying to get CamUI working... sorry for the delay.
I copied both 2.0.0 and 2.0.1 to my Raspberry PI Zero 2W.
2.0.0 works as before.
2.0.1 will not launch for me. I've attached the command window log, perhaps it will help.

Could you do me a favor and try and run an update... There has been a few updates in picamera2 and libcamera in the last few weeks. Technically should not effect what I am doing but I would like to rule that out

[johnson29630]

Before my attempt to run CamUI 2.0.1 I had run a system update on July 25 using this command:
sudo apt update && sudo apt upgrade -y
Just to be sure I just re-ran the system update.
CamUI 2.0.1 still does not launch.

PS: I am not clear on the git command syntax to install specific versions (of CamUI). I used the git web interface to access and download .zip files for the target versions, and manually installed the files to my RPI.

[monkeymademe]

in the folder for for 2.0.1 type

git pull

See if it updates the version that might be it.... Maybe
