gstreamer capture

[dabenpb]

Whooops, wrong thread ... I will repost in general.

Is the gstreamer backend compiled into the opencv for emgcv? I would like to use similar to this python capture:

import cv2
cap = cv2.VideoCapture('videotestsrc ! videoconvert ! appsink')
while True:
ret,frame = cap.read()
cv2.imshow('',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cv2.destroyAllWindows()
cap.release()
