exposing the file with api preference constructor of VideoCapture

[kwatters]

This is a pull request that exposes the VideoCapture constructor that includes the apiPreference. I think this is what Spawn32 is looking for in #1021

Looks good, let's do the same for the other constructors!

[kwatters]

I assume you're referring to all of the following:

  VideoCapture capture = new VideoCapture();
  VideoCapture capture = new VideoCapture(BytePointer filename);
  VideoCapture capture = new VideoCapture(int index);
  VideoCapture capture = new VideoCapture(long size);
  VideoCapture capture = new VideoCapture(Pointer p);
  VideoCapture capture = new VideoCapture(String filename);
  VideoCapture capture = new VideoCapture(BytePointer filename, int apiPreference);
  VideoCapture capture = new VideoCapture(String filename, int apiPreference);

I could work some logic into handle each of those case if you want. I don't know if there's much benefit to the new VideoCapture(); constructor. This is probably a slightly larger refactor...

No, I mean OpenCVFrameGrabber's constructors. We only really need File and deviceNumber.

[saudet]

Or maybe just File, it doesn't support apiPreference for deviceNumer?

[kwatters]

I'm pretty sure file & device number are mutually exclusive. I added a constructor that allows file + api preference.
