[BUG] Unable to open camera when building opencv from source #38

Closed squeakus closed 3 years ago

squeakus commented 3 years ago

Describe the issue Hi,I am unable to access the camera when I build from source, even with gstreamer enabled. I get the following error

nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)1280, height=(int)720, format=(string)NV12, framerate=(fraction)60/1 ! nvvidconv flip-method=0 ! video/x-raw, width=(int)1280, height=(int)720, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink Unable to open camera

If I uninstall and install from apt it works fine so it must be some other dependency I am missing. I need to build it from source to enable the nvidia optical flow contrib packages

What version of L4T/JetPack L4T/JetPack version: R32 (release), REVISION: 5.1, GCID: 26202423, BOARD: t210ref, EABI: aarch64, DATE: Fri Feb 19 16:45:52 UTC 2021 What version of OpenCV OpenCV version: 4.5 Python Version 3.8

To Reproduce Steps to reproduce the behavior: For example, what command line did you run? python3 simple_camera.py

Expected behavior run the camera app and show output

Additional context Add any other context about the problem here.

My bad, when I checked the build with print(cv2.getBuildInformation()) it turned out that gstreamer was failing silently I needed to install additional gstreamer dev packages.

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

Hey, I am facing a similar issue. I tried installing the additional packages, but I am still getting the same error, can you please give me any idea how to solve it?
