+// the OMX node should operate as normal, and expect UseBuffer calls to set its
+// buffers.  This is the mode that will be used when CPU access to the buffer is
+// required.
+//
+// When Android native buffer use has been enabled for a given port, the video
+// color format for the port is to be interpreted as an Android pixel format
+// rather than an OMX color format.  The node should then expect to receive
+// UseAndroidNativeBuffer calls (via OMX_SetParameter) rather than UseBuffer
+// calls for that port.

+// and OMX components, interpretation of the buffer data is up to the

+// some information helpful for the receiver to locate the actual data.
+// The buffer receiver thus needs to know how to interpret what is stored
+// in these buffers, with mechanisms pre-determined externally. How to
+// interpret the meta data is outside of the scope of this method.
+//
+// Currently, this is specifically used to pass meta data from video source
+// (camera component, for instance) to video encoder to avoid memcpying of
+// input video frame data. To do this, bStoreMetaDta is set to OMX_TRUE.
