If gstreamer is already installed on a jetson nano device. Can we change the status to YES in a virtual environment or we need to install the gstreamer again?If then how we can do it?
if you mean - gstreamer support for opencv’s videoio module ;-
you have to build the opencv libs with gstreamer installed
(you cannot change anything later …)
Can you tell us how to build opencv libs with gstreamer in virtual environment
first, what does print(cv.getBuildInformation()) say?
how did you install the OpenCV package for python?
if you know: where did you get it from?
if you know: who made the package?
