Summary of your issue

It seems that OpenCV 3.2 offers a constructor overload for VideoCapture that allows a device to be defined and captured by device path (such as /dev/video0). Specifications here: https://docs.opencv.org/3.2.0/d8/dfe/classcv_1_1VideoCapture.html#a85b55cf6a4a50451367ba96b65218ba1

Environment

Windows 10 x64, Raspbian Stretch (irrelevant tbh)

What did you do when you faced the problem?

This is not an issue. This is an enhancement to be able to open a device through a path instead of index.

Example code:

N/A

Output:

N/A

What did you intend to be?

An exposure of this constructor so that we can open a device through a path, rather than index
