UNSOLVED RAW-MIPI-SC132M camera working in raspberry pi 5. Cannot be configured to work with the libcamera2 and opencv libraries

alex_ai

Hi @veye_xumm, sorry for confusion, in previous time you guided me to install custom libcamera for veye_mvcam driver and seems like this step is outdated (but I'm still using libcamera).

@Sheko try another pipeline in openCV:

v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1920, height=1080,framerate=30/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1

@alex_ai

command not found(((

~ $ v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1920, height=1080,framerate=30/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1
bash: v4l2src: command not found

I got the title wrong - I meant Picamera2. I need to start working in Opencv first.

@sheko
This is pipeline which need place to openCV instead:

cap = cv2.VideoCapture('/dev/video0')

to run it from command line you need use gstreamer, try :

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1920, height=1080,framerate=30/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1

@sheko please update pipeline with your camera parameters (width, height, framerate). I just copied mine.

Sheko

@alex_ai How to do this?

Sheko

@veye_xumm said in RAW-MIPI-SC132M camera working in raspberry pi 5. Cannot be configured to work with the libcamera2 and opencv libraries:

Требуется прямой вызов через v4l2 API.

Direct call via v4l2 API? What does that mean? Give an example for Python.

alex_ai

@sheko
As I see your standard camera parameters are: 1080x1280 120fps
And as it configured in python script for first step try:

cap = cv2.VideoCapture('v4l2src device=/dev/video0')

if still failing try with passing parameters to gstreamer:

cap = cv2.VideoCapture('v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1080, height=1280,framerate=120/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1')

or from command line to check if gstreamer works without python

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY, width=1080, height=1280,framerate=120/1 ! videoconvert ! video/x-raw,format=GRAY8 ! appsink sync=1

if still failing try RAW8 format

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=RAW8, width=1080, height=1280,framerate=120/1 ! appsink sync=1

if still failing, can't help, I don't have this sensor.

It turns out the manufacturer is ignoring requests for help. Only kind and caring people are helping... The problem remains unresolved.

@sheko Sorry, I just got back from the Chinese New Year holiday. Regarding using the RAW-MIPI-SC132M on the Raspberry Pi 5, I suggest you primarily refer to this document. It covers driver installation, how to use the V4L2 mode, and methods for previewing using OpenCV.
