+        OpenCV creates YUV420 frame from BGR
+        This frame has following structure and size:
+        width, height - dim of input frame
+        width, height * 1.5 - dim of output frame
+
+                  width

+
+         width // 2   width // 2
+
+        Y, U, V can be extracted using slices and joined in one list using itertools.chain.from_iterable()
