The '''RidgeRun OpenCV fork''' is a modified version of the project with various improvements around speed and efficiency. While some changes are general (i.e.: any platform will benefit from them), others are specific to the NVIDIA Jetson family. | The '''RidgeRun OpenCV fork''' is a modified version of the project with various improvements around speed and efficiency.

import cv2 as cv | |||
PIPE = "videotestsrc pattern=black ! \ | |||
video/x-raw,format=BGR,width=1920,height=1080 ! \ | |||
perf print-arm-load=true ! \ | |||
appsink sync=false drop=false max-buffers=3" | |||
cap = cv.VideoCapture(PIPE, cv.CAP_GSTREAMER) | |||
while True: | |||
ret, frame = cap.read() | |||
cap.release() | |||
cv.destroyAllWindows() | |||
