StereoPi Forum

hello everyone !
i am using the stereoPi v2 with CM4 when i ran the 1_test.py i get the following error
mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM)
mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)

During handling of the above exception, another exception occurred:

and thank you in advance for your time and help

It's either the camera ribbon cable connection issue, or GPU memory settings. If you're using our OpenCV image, memory settings should be fine.

Could you please run these commands in the terminal one by one and share the results:

raspivid -cs 0

raspivid -cs 1

upd> If you altered test.py with your own resolution (like 12Mpix for HQ camera), adjust the gpu_mem setting in config.txt to 384 or 512 Mb.

i didn't altered the test.py but i changed gpu_mem to 512Mb but the same error .i attached the results for the 2 commands you asked me to do and after that i tried to change the mode to legacy but i didn't find the option in the raspi-config as you can see.do i need to disconnect the ribbon and reconnect it.

It looks like you're using the fresh RaspiOS, which does not have the MMAL/raspivid/raspistill video stack.

The easiest way is to get the ready-to-use OpenCV image here: https://www.mediafire.com/folder/nzr90vj8wp1l3/SLP

i am sorry i am kinda new to this can give me further instructions ,is there any way to get the legacy camera stack on .
i am sorry in advance for the trouble ,thank you for your guidance.

Okay, here are a few simple steps:
1. Using the link I've provided, please download the file "OpenCV_Buster..."
2. Insert SD card to your pc, and, using Balena Etcher software, write this image to the SD card
3. Insert this card to your StereoPi. Enjoy!

thank you for your help,i am gonna test these steps tomorrow, i hope this works.
update:
it finally worked thank you so much.

i need to use yolov8 in my project and when i try to install ultralytics it depends on pytorch>=1.8 but it's impossible to install pytorch for the 32bits raspi os that you provided .is there any busterOS images for 64bits or if there is any solution to this problem.

Sorry, we don't have a ready-to-use 64bit image.

will the parametres that are in calib_data folder work (i have IMX219-160 camera) ?

another question why there are two folders 240 and 480?what are they used for ?

%Run 5_dm_tune.py
