Hi
in this [post](http://answers.opencv.org/question/64600/changing-resolution-of-front-lifecam-on-ms-surface-pro/) videocapture constructor is cv::VideoCapture INvidstream(CV_CAP_DSHOW | 1);
Where can I find in doc that constructor for videocapture could be a binary or between device and interface?
I have found [this](http://docs.opencv.org/master/d8/dfe/classcv_1_1VideoCapture.html#ae21bd36b8f10103ff44e2b4d1996826b) and [this](http://docs.opencv.org/modules/highgui/doc/reading_and_writing_images_and_video.html#videocapture-videocapture) but I cannot found this binary or.
Thanks for yours answers
