(raspberry pi 4 and Python) raspberry Camera mode raise picamera.exc.PiCameraMMALError and picamera.exc.PiCameraError

system: raspberry pi 4 model B, use external usb logitech camera

I'm follow the youtube tutorial but get picamera.exc.PiCameraMMALError andpicamera.exc.PiCameraError

relate discussion on other site 2021 (I didn't get their solution): "Camera issue, no idea what the problem is"
https://forums.raspberrypi.com/viewtopic.php?t=324702

- the python code:

from picamera import PiCamera
import time


print("= = = = = == = = = ")
camera = PiCamera()

camera.start_preview()
time.sleep(2)

camera.capture("test.jpg")

- the whole output:

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:

You need to enable Pi-camera in setting.That's what error is saying.

  1. Type sudo raspi-config in terminal & hit enter.
  2. Go to interface options
  3. Go to p1 Legacy camera and hit enetr After enable it.

4.Reboot

As you mentioned external camera What happens here I guess is raspberry Pi has onboard camera socket. WHen we conncet camera to it Raspberry pi assigns as device id =0 internally. When we connect second camera(which is through USB yourcase). It will be assigned witj device id =1 ...As you not mentioned which device Id it deafultly checking at devic id=0 which not exists. Let me check documention how to re assign Id. I Know how to do that opencv but, Never tried in this pi camera module. in meanwhile try opencv

pip install opencv-contrib-python

After installation of library

import cv2
  
  
# define a video capture object
vid = cv2.VideoCapture(1) ########## 1- device id =1###if 1 deosn't work try 2
  
while(True):
      
    # Capture the video frame
    # by frame
    ret, frame = vid.read()
  
    # Display the resulting frame
    cv2.imshow('frame', frame)
      
    # the 'q' button is set as the
    # quitting button you may use any
    # desired button of your choice
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
  
# After the loop release the cap object
vid.release()
# Destroy all the windows
cv2.destroyAllWindows()
