Introduction
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 fork is hosted at:
https://github.com/RidgeRun/opencv
Building the Project
Follow the instructions in our Compiling OpenCV from Source page. Make sure you select:
- RidgeRun fork
- GStreamer support
- CUDA support (if applicable)
Enhancements
GStreamer Video Capture
Tested under the following conditions
- OpenCV Version: 4.4.0
- FPS and CPU usage taken with the GstPerf element.
- The following script:
<script lang=python>
- !/usr/bin/env python3
import cv2 as cv
PIPE = "videotestsrc pattern=black ! \
video/x-raw,format=BGR,width=1920,height=1080 ! \
appsink sync=false drop=false max-buffers=3"
cap = cv.VideoCapture(PIPE, cv.CAP_GSTREAMER)
while True:
ret, frame = cap.read()
cv.imshow('display', frame)
if cv.waitKey(1) & 0xFF == ord('q'):
break
cap.release() cv.destroyAllWindows() </script>
