In the configure process, GstInference searches for OpenCV 2.X or 3.X, in case of systems with OpenCV 4.1 installed, this package is not detected and inference overlay plugins are discarded.
Example: Jetson Xavier running JetPack 4.3
libopencv-dev is already the newest version (4.1.1-2-gd5a58aa75).
After configure:
configure: checking feature: OpenCV computer vision library
configure: for plug-ins: opencv
checking for OPENCV... no
configure: No package 'opencv' found
configure: *** These plugins will not be built: opencv
For this cases, We must add a section to clarify OpenCV required version:
I had to build OpenCV 3.4 from sources to enable inference overlay plugins
