Failed to initialize vdo stream

[danudeep90]

Hi,

I am trying to run https://github.com/AxisCommunications/acap-computer-vision-sdk-examples/tree/main/object-detector-python
application on AXIS camera P3268 LV Dome Camera. But, when i run the service, i am getting an error as "Failed to initialize vdo stream".

I suspect the error is in reading frames. I am unable to get any frames.

I even tried changing the videoCapture source in the code below to 0, but still doesnt work

cap = cv2.VideoCapture(1)
cap.set(cv2.CAP_PROP_FPS, 5)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 480)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 320)
cap.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter_fourcc(*"RGB3"))

Can someone help me on this ?

Hello @danudeep90

Did you run the example 'as it is' following the instructions or did you make changes?
Did you use docker compose?
In order for the container to access the video stream, it has to have some volumes that we set up in the docker-compose file. Maybe you are starting the example without it?

@Corallo : firmware version is 10.12.91. should i do an upgrade ?
no errors as such, frame is None, when i tried to print(frame) after line
_, frame = cap.read()

Yes, the example is not compatible anymore with fw older than 11.0.
Either you update your firmware, (download the new one here)
or you use an older version of the example (not recommended).

I see an option on the GUI on maintenance section, firmware, I can use it to upgrade right ?

[Corallo]

Yes, the upgrade can be done using the GUI, follow the instructions there.
