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:

#!/usr/bin/env python3

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()
    cv.imshow('display', frame)
    if cv.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv.destroyAllWindows()
