OpenCV installation for AVerMedia Jetson Nano

[jg03gt]

I am attempting to install OpenCV on my AVerMedia Jetson Nano (Version B01) with an EN715 carrier board. I have attempted this installation script by: mdegans GitHub - mdegans/nano_build_opencv: Build OpenCV on Nvidia Jetson Nano
however, I get the following error in my config log file
configlogfail.docx (10.2 KB)

I also want to use this post to identify other AVerMedia D111NO kit users as I have not seen any posts about this particular configuration of the Jetson Nano. This Jetson Nano is different as it flashes serially and doesn’t have opencv already installed on it. I tried installing just the python version, but numpy would not get built. In the short term, I need a way to capture and record video using linux tools, but in the long-term I need opencv installed on the ARM architecture of the Jetson Nano. So far, I have been able to stream video using v4l-utils and qv4l2, however it does not allow me to capture and record frames. Does anyone know any way to get a linux tool to do this on the Jetson Nano? Or any other suggestions for OpenCV on the Jetson Nano?

Thanks.

Hi,
You may check the samples and give it a try:
Doesn't work nvv4l2decoder for decoding RTSP in gstreamer + opencv - #3 by DaneLLL
V4l2src using OpenCV Gstreamer is not working in Jetson Xavier NX - #3 by DaneLLL
Issue with multi-camera gstreamer capture using OpenCV - #6 by DaneLLL

Suggest run a gstreamer pipeline in cv2.VideoCapture() to get the frame data in cv::Mat

Thank you I will check them out. I was able to get OpenCV installed without building from source by just running sudo apt-get install python3-opencv since it did not have a pre-compiled version of opencv installed already. I will check out the sample and see if it is compatible with memory mapped I/O stream of my IR camera.
