tunneling. The return codes for this method can be used to

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.

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

this parameter is 0x0 the component should setup the port for

nPortOutput is used indicate the port the component should

When nPort is an input port the component should review the setup

provided by the component with the output port.
