determine if tunneling is not possible, or if tunneling is not
supported.
Base profile components (i.e. non-interop) do not support this
method and should return OMX_ErrorNotImplemented
The interop profile component MUST support tunneling to another
interop profile component with a compatible port parameters.
A component may also support proprietary communication.
If proprietary communication is supported the negotiation of
proprietary communication is done outside of OMX in a vendor
specific way. It is only required that the proper result be
returned and the details of how the setup is done is left
to the component implementation.
When this method is invoked when nPort in an output port, the
component will:
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.
@param [in] hComp
Handle of the component to be accessed. This is the component
handle returned by the call to the OMX_GetHandle method.
@param [in] nPort
nPort is used to select the port on the component to be used
for tunneling.
@param [in] hTunneledComp
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
nPortOutput is used indicate the port the component should
tunnel with.
@param [in] pTunnelSetup
Pointer to the tunnel setup structure. When nPort is an output port
the component should populate the fields of this structure. When
When nPort is an input port the component should review the setup
provided by the component with the output port.
