// interpret the meta data is outside of the scope of this parameter.

//

* MetadataBufferType defines the type of the metadata buffers that
* can be passed to video encoder component for encoding, via Stagefright
* media recording framework. To see how to work with the metadata buffers
* in media recording framework, please consult HardwareAPI.h
*
* The creator of metadata buffers and video encoder share common knowledge
* on what is actually being stored in these metadata buffers, and
* how the information can be used by the video encoder component
* to locate the actual pixel data as the source input for video
* encoder, plus whatever other information that is necessary. Stagefright
* media recording framework does not need to know anything specific about the
* metadata buffers, except for receving each individual metadata buffer
* as the source input, making a copy of the metadata buffer, and passing the
* copy via OpenMAX API to the video encoder component.
*
* The creator of the metadata buffers must ensure that the first
* 4 bytes in every metadata buffer indicates its buffer type,
* and the rest of the metadata buffer contains the
* actual metadata information. When a video encoder component receives
* a metadata buffer, it uses the first 4 bytes in that buffer to find
* out the type of the metadata buffer, and takes action appropriate
* to that type of metadata buffers (for instance, locate the actual
* pixel data input and then encoding the input data to produce a
* compressed output buffer).
*
* The following shows the layout of a metadata buffer,
* where buffer type is a 4-byte field of MetadataBufferType,
* and the payload is the metadata information.

1. Populate the pTunnelSetup structure with the output port's
requirements and constraints for the tunnel.
When this method is invoked when nPort in an input port, the
component will:
1. Query the necessary parameters from the output port to
determine if the ports are compatible for tunneling
2. If the ports are compatible, the component should store
the tunnel step provided by the output port
3. Determine which port (either input or output) is the buffer
supplier, and call OMX_SetParameter on the output port to
indicate this selection.
The component will return from this call within 5 msec.

Handle of the component to tunnel with. This is the component
handle returned by the call to the OMX_GetHandle method. When
this parameter is 0x0 the component should setup the port for
communication with the application / IL Client.
@param [in] nPortOutput
