This might be an issue with your OpenCV installation or Gstreamer either. I see you are using Gstreamer for video capture although the command takes OpenCV video capture functions. Could you test with
$ ./darknet yolo demo cfg/yolo-face.cfg yolo-face_final.weights <video_file.mp4> or with webcam $ ./darknet yolo demo cfg/yolo-face.cfg yolo-face_final.weights for a sanity check?
