If you want to use existing buffer without copping it use:
Mat(rows, cols, CV_16U, your_buffer, stride_of_buffer);
It will create Mat that will contain your buffer. Note that Mat won't take the responsibility of releasing it, you will have to do that yourself.

It doesn't really matter if the buffer is part of video or something else.
And the last parameter is optional (stride_of_buffer). You don't need it your buffer is continuous in memory.
