// 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).
// 
// Return Value:
//      An HResult.  See the Direct Show SDK and COM SDK documentation for more 
// information on interpreting HRESULTs.
// 
// 
// 
// 
// HResult PauseChain( [in] IBaseFilter *pStartFilter, [in] IBaseFilter *pEndFilter );
// 
//      PauseChain() switches all the filters in a chain to the paused state.  If it cannot
// switch one of the filtres into the paused state, all the filters in the chain are
// stopped.  This method can only be called if the filter graph is paused.
// 
// 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::StopChain( A, NULL ) would stop filter A.   
// IFilterChain::StopChain( G, NULL ) would stop filters G and H.  
// IFilterChain::StopChain( C, NULL ) would stop filters C and D.  Finally, 
// IFilterChain::StopChain( E, NULL ) would fail because E cannot be in a filter 
// chain (see the Filter Chain Definition section for more information).
//

// 
// 
// 
// HResult StopChain( [in] IBaseFilter *pStartFilter, [in] IBaseFilter *pEndFilter );
// 
//  StopChain() switches all the filters in chain to the stopped state.
//
// 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::StopChain( A, NULL ) would stop filter A.

// IFilterChain::StopChain( C, NULL ) would stop filters C and D.  Finally,
// IFilterChain::StopChain( E, NULL ) would fail because E cannot be in a filter

// 
// 
// 
// 
// 
// HResult RemoveChain( [in] IBaseFilter *pStartFilter, [in] IBaseFilter *pEndFilter );
// 
//      RemoveChain() removes every filter in a chain from the filter graph.  
// The filters can be removed while the graph is running.
// 
// Parameters:
// - pStartFilter [in]
//      The first filter in the filter chain.  Note that this can be the same

// DWORD bit masks that specify where the RGB data can be found in the image
// (For more information regarding BITMAPINFOs see the Win32 documentation)

// The rcSource and rcTarget fields are not for use by filters supplying the
// data. The destination (target) rectangle should be set to all zeroes. The

// if the video is 352x288 pixels then set it to (0,0,352,288). These fields
// are mainly used by downstream filters that want to ask the source filter
// to place the image in a different position in an output buffer. So when
// using for example the primary surface the video renderer may ask a filter
// to place the video images in a destination position of (100,100,452,388)

// System-defined event codes
// ==========================
//
// There are three types of system-defined event codes:
//
// 1.  Those which are always passed through to the application
//     (To be collected by calls to GetEvent or within WaitForCompletion.)
//     (e.g. EC_ERRORABORT, EC_USERABORT.)
//
// 2.  Those which are pure internal and will never be passed to
//     the application.  (e.g. EC_SHUTDOWN)
//
// 3.  Those which have default handling.  Default handing implies that
//     the event is not passed to the application.  However, default
//     handling may be canceled by calling
//     IMediaEvent::CancelDefaultHandling.  If the default handling is
//     cancelled in this way, then the message will be delivered to the
//     application and the application must action it appropriately.
//     Default handling can be restored by calling RestoreDefaultHandling.
//
// We will refer to these events as application, internal and defaulted
// events respectively.
//
// System-defined events may have interface pointers, BSTR's, etc passed
// as parameters.  It is therefore essential that, for any message
// retrieved using GetEvent, a matching call to FreeEventParams is made
// to ensure that relevant interfaces are released and storage freed.
// Failure to call FreeEventParams will result in memory leaks, if not
// worse.
//
// Filters sending these messages to the filter graph should not AddRef()
// any interfaces that they may pass as parameters.  The filter graph
// manager will AddRef them if required.  E.g. if the event is to be queued
// for the application or queued to a worker thread.

// Each event listed below is immediately followed by a parameter list
// detailing the types of the parameters associated with the message,
// and an indication of whether the message is an application, internal
// or defaulted message.  This is then followed by a short description.
// The use of "void" in the parameter list implies that the parameter is not
// used.  Such parameters should be zero.

// Other defined EC_ regions:
// DVD event codes           0x0100 - 0x0150 (dvdevcod.h)
// audio device event codes  0x0200 - 0x0250 (audevcod.h)
// WindowsMedia SDK-originated events 0x0251 - 0x0300 (see below)
// MSVIDCTL                  0x0301 - 0x0325 (msvidctl.idl)

This is a summary of what media types/specifiers will be required for all DVD+DSS+DVB+DTV MPEG decoders.
These media types are what the decoder driver must accept, hardware support for all of these media types
may or may not actually be provided by the decoder natively.  These media types are intended to define
the "officially" supported MPEG/AC-3 media types that all WHQL certified decoders must implement.  This
specifically includes driver and/or hardware support for all the required standards and dialects.

All MPEG video decoders must support all of the MPEG video modes shown as [required] below.
All MPEG audio decoders must support all of the MPEG audio modes shown as [required] below.
All AC-3 audio decoders must support all of the AC-3 audio modes shown as [required] below.
The line items shown as [optional] need not be implemented, but are possible formats that might be implemented.

Note that the input/output pin formats are defined by 2 or 3 GUIDs: TYPE, SUBTYPE, and maybe SPECIFIER.
The specifiers are included if the data format is a "dialect" that needs to be differentiated during decoding.
The decoder MUST be prepared to deal with ALL requests for _required_ "Standard" formats OR _required_ "Dialects".

Note that the SPECIFIER GUIDs normally identify particular versions of MPEG such as DSS and DVD.
This approach was taken to minimize the number of DSS/DVB/DVD/DTV etc. media SUBTYPES.
These specifiers are currently required to disambiguate MPEG syntax _parsing_ by the decoder
using alternate parsing routines or downloadable firmware or hardware decode settings.

In the future these specifiers will be extended to cover new KS MPEG flavors such as DVB and DTV.
Thus, the optional specifiers will be subject to clarification and/or definition as they are needed.

Important note: Per the ITU MPEG specs, MPEG 2 media may contain pure MPEG 1 syntax and
any "MPEG 2" PES packets may actually contain MPEG 1 payloads and MPEG 1 syntax.  Some MPEG
broadcasts can revert from MPEG2 to MPEG1 format data at their discretion, without warning.

CAUTION: Decoders MUST attempt to process MPEG data AS SOON AS POSSIBLE after reception.
In particular, elementary MPEG or MPEG PES packet streams should not be aggregated into DVD
"pack headers" internally before submission to the codec hardware if AT ALL POSSIBLE.  The
reason is that mpeg data may need to be processed immediately but there may be no additional
MPEG data forthcoming to fill up the PES packet OR DVD "pack" in a timely fashion.  This is
particularly true of MPEG dialects that utilize "repeat field signally" to reuse the last
decoded MPEG video field.

//  Abstract:
//      This header contain structures and peroperty sets for
//      interfacing to an external device, like a DV.
//      The code is modeled after DirectShow's Vcrctrl Sample
//      (VCR Control Filter). It contain IAMExtDevice,
//      IAMExtTransport, and IAMTimecodeReader interfaces, and
//      a new interface IAMAdvancedAVControl() is added
//      for additional advanced device controls.
//
//      Note:  (From DShow DDK)
//          The VCR control sample filter, Vcrctrl, is a simple
//          implementation of the external device control interfaces
//          that DirectShow provides. Vcrctrl provides basic transport
//          control and SMPTE timecode-reading capabilities for certain
//          Betacam and SVHS videocassette recorders with RS-422 or RS-232
//          serial interfaces (see source code for specific machine types
//          supported).
//
//      Note:  some methods in IAM* interfaces may not be
//             used and will return not implemented.

   Notes:
       The derived class is meant to do most work to initialize streaming
       in AllocateStreamingResources rather than when types are set.

       This centralizes the work to one
       clear place based on the types set for all streams.

       The derived class implements locking.

       The derived class implements the IUnknown methods

   Usage example (1 input and 1 output) :
   class CMyDMO : public IMediaObjectImpl<CMyDmo, 1, 1>,
                  ...
}

  Delphi class tries to follow C++ template class as much as possible.
  But in addition to original C++ template it's already implements
  multi-threading support due to:
    1) AddRef, Release - realized as thread safe in TComObject
    2) Lock(), Unlock() - uses critical section.

  If you do not need support for thread-safe processing you can save some
  system resources by not calling Windows functions (InterlockedInclerent,
  InterlockedDecrement, EnterCriticalSection, LeaveCriticalSection). This
  can be don by overriding these funtions in derived class:
  ObjAddRef, ObjRelease, Lock(), Unlock()
}
