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. +// +// +// --->|---| |---|---> +// | C |--->| D | +// |---| |---|--->|---| |---|--->|---| |---| |---| |---| +// | A |--->| B | | E |--->| F |--->| G |--->| H | +// |---| |---|--->|---|------------>|---| |---| |---| |---| +// | I |---> +// --->|---|---> +// +// |---| |---| |---| +// | J |--->| K |--->| L | +// |---| |---| |---| +// +// Example Filter Graph +// +// +// +// IFilterChain Methods Documentation +// +// 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.
