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.
