Issue submission checklist

• [. ] I report the issue, it's not a question
• [. ] I checked the problem with documentation, FAQ, open issues,
  answers.opencv.org, Stack Overflow, etc and have not found solution
• [. ] I updated to latest OpenCV version and the issue is still there
• [ .] There is reproducer code and related data files: videos, images, onnx, etc

Can be solved by just adding a line to modules\videoio\src\cap_dshow.cpp

#define NO_DSHOW_STRSAFE

just above

#include "DShow.h"

I will submit this as a pull request.
