Opencv with video backend GStreamer issue
I am completely new with OpenCV and Gstreamer. I am getting an error which I cannot find a answer anywhere.
I have setup Opencv manually with Gstreamer as videoIO backend. On creating videowriter i get the error. Please check my code and logs below.
fourcc = cv2.VideoWriter_fourcc(*'H264')
video = cv2.VideoWriter('/tmp/15.mp4', fourcc, 5.0, (width, height))
I get the error 'no source element for URI "/tmp/15.mp4"'

Please read Under what circumstances may I add “urgent” or other similar phrases to my question, in order to obtain faster answers? - the summary is that this is not an ideal way to address volunteers, and is probably counterproductive to obtaining answers. Please refrain from adding this to your questions.
