This method adds a filter to the graph and names it by using the pName parameter.
Syntax
HRESULT AddFilter(
IBaseFilter* pFilter,
LPCWSTR pName
);
Parameters
- pFilter
[in] Filter to add to the graph.
- pName
[in] Name of the filter.
Return Value
Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.

E_INVALIDARG |
Invalid argument. |
E_NOTIMPL |

Remarks
The name of the filter can be NULL, in which case the filter graph manager will generate a name. If the name is not NULL and is not unique, this method will modify the name in an attempt to generate a new unique name. If this is successful, this method returns VFW_S_DUPLICATE_NAME. If it cannot generate a unique name, it returns VFW_E_DUPLICATE_NAME.
AddFilter calls the filter's IBaseFilter::JoinFilterGraph method to inform the filter that it has been added. AddFilter must be called before attempting to use the IGraphBuilder::Connect, IFilterGraph::ConnectDirect, or IGraphBuilder::Render method to connect or render pins belonging to the added filter.
