// Filter Chain Definition
|
|
//
|
|
// Filter chains have the following properties:
|
|
//
|
|
// - Each filter chain has one or more filters.
|
|
//
|
|
// - Each filter in a filter chain has at most one connected input pin and one
|
|
// connected output pin. For example, filters A, C, D, F, G, H, I, J and K
|
|
// (see the diagram below) can be in a filter chain because each one has at
|
|
// most one connected input pin and one connected output pin.
|
|
//
|
|
// - Any filter in a chain is reachable by any other filter in the chain.
|
|
// For example, in the filter chain F-G-H, F can reach H by following the F-
|
|
// G connection to G and then following the G-H connection to H. Filters F
|
|
// and J cannot be in the same filter chain because J is not reachable from
|
|
// F. Anotherwords, there no sequence of connected filters between F and J.
|
|
//
|
|
// - The start filter is the only filter in the filter chain who's input
|
|
// pin is not connected to another filter in the chain. For instance, F is
|
|
// the start filter in F-G-H because F's input pin is connected to E and E
|
|
// is not in the filter chain. G's input pin is connected to F and H's is
|
|
// connected to G. Both F and G are in the filter chain.
|
|
//
|
|
// - The end filter is the only filter in the filter chain who's output pin
|
|
// is not connected to another filter in the chain. For example, in the
|
|
// filter chain J-K, K is the end filter because K's output pin is
|
|
// connected to L. J's output pin is connected to K and K is in the J-K
|
|
// filter chain.

// HRESULT StartChain( [in] IBaseFilter *pStartFilter, [in] IBaseFilter *pEndFilter );

//
|
|
// StartChain() switches all the filters in the chain into the running state
|
|
// If one of the filters will not switch to the running state, then all the filters
|
|
// in the chain are stopped. This method can only be called if the filter graph is
|
|
// running.
|
|
//
|
|
// Parameters:
|
|
// - pStartFilter [in]
|
|
// The first filter in the filter chain. Note that this can be the same
|
|
// filter as pEndFilter .
|
|
//
|
|
// - pEndFilter [in]
|
|
// The last filter in the filter chain. Note that this can be the same
|
|
// filter as pStartFilter. If pEndFilter is NULL then the filter chain extends
|
|
// from pStartFilter to the last downstream filter which can be in a filter chain.
|
|
// For example, IFilterChain::StartChain( A, NULL ) would start filter A.
|
|
// IFilterChain::StartChain( G, NULL ) would start filters G and H.
|
|
// IFilterChain::StartChain( C, NULL ) would start filters C and D. Finally,
|
|
// IFilterChain::StartChain( E, NULL ) would fail because E cannot be in a

|
// filter chain (see the Filter Chain Definition section for more information).
|
|
//

|
// information on interpreting HRESULTs.

//
|
|
// Parameters:

|
// - pStartFilter [in]

// For example, IFilterChain::StopChain( A, NULL ) would stop filter A.
