Hi,

I try to create dll using opencv methods for unity but I run my dll with split function ,my app crash

extern "C" void __declspec(dllexport) __stdcall Test() { Mat frame; capture >> frame; if (frame.empty()) return;

std::vector<mat> channels(3);

split(frame, channels);

}

I cant use Vector in split ,I try like below

extern "C" void __declspec(dllexport) __stdcall Test() { Mat frame; capture >> frame; if (frame.empty()) return;

Mat channles[3];

split(frame, channels);

}

it works but I need to use vector version How can I solve my problem ?

please help me :(
