is this color conversion only for video capture, or can be used for other cases?

It has been made private to VideoCapture by purpose. But sure- it is standard
conversions to I420.

+  static void ConvertToI420(VideoCaptureDevice::Format src_format,
+                            const uint8* src,
+                            int width,
+                            int height,
+                            uint8* dst);

+ private:
+  static void ConvertYUY2ToI420(const uint8* src,

+                                int height,
+                                uint8* dst);
+  static void ConvertRGB24ToI420(const uint8* src,
