// When Android native buffer use is disabled for a port (the default state),

// 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.

// When meta data is stored in the video buffers passed between OMX clients

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

// buffer receiver, and the data may or may not be the actual video data, but

// 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.

// If bStoreMetaData is set to false, real YUV frame data will be stored

// in the buffers. In addition, if no OMX_SetParameter() call is made

// with the corresponding extension index, real YUV data is stored

// in the buffers.
