Hi, after a while I wanted to restart using my xavier NX to make same vide analyses with opencv. I tried to build a python programm, using python 3.9.25, and opencv 4.12.0. I have raspi cam’s on both sockets, but none of them seems to return a frame. my code is rather simple import cv2 print(cv2._…

Hi, Is this a duplicate of the below topic? [image] Python opencv on jetpack 5.1.4 Jetson Xavier NX Hi, I want to reactivate my old Xavier NX to build a robot head. I want to use 2 pi cameras for the eyes. Does the jetpack 5.1.4 or 5.1.5 support python openc…

Sorry for the late response. Is this still an issue to support? Any result can be shared?

Hi @jetson1 , Have you tried testing the pipeline using gst-launch to confirm that it is running correctly? I noticed a typo in your pipeline in the height setting. You can test the pipeline using: gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! “video/x-raw(memory:NVMM), width=3264, height=2464, fr…

hi, i tried the following command from the command line : gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! "video/x-raw(memory:NVMM), width=3264, height=2464, framerate=21/1, format=NV12" ! nvvidconv flip-method=2 ! video/x-raw, width=800, height=600, format=BGRx ! videoconvert ! video/x-raw, format=B…

You can rebuild opencv to add gstreamer support, you can use the following wiki Compiling_OpenCV_from_Source , make sure to add -D WITH_GSTREAMER=ON \ t…

I followed the compilation wiki. and used the following cmake command cmake -B build -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_GENERATE_PKGCONFIG=ON -D BUILD_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=OFF -D INSTALL_C_EXAMPLES=OFF -D PYTHON_EXECUTABLE=$(which python2) …
