-// Memory allocators

-// to provide a memory allocator that can provide sample objects. A
-// sample object supports the IMediaSample interface.
-//
-// CBaseAllocator handles the management of free and busy samples. It
-// allocates CMediaSample objects. CBaseAllocator is an abstract class:
-// in particular it has no method of initializing the list of free
-// samples. CMemAllocator is derived from CBaseAllocator and initializes
-// the list of samples using memory from the standard IMalloc interface.
-//
-// If you want your buffers to live in some special area of memory,
-// derive your allocator object from CBaseAllocator. If you derive your
-// IMemInputPin interface object from CBaseMemInputPin, you will get
-// CMemAllocator-based allocation etc for free and will just need to
-// supply the Receive handling, and media type / format negotiation.

-
- We use a lazy signalling mechanism for waiting for samples.
- This means we don't call the OS if no waits occur.
-
- In order to implement this:
-
- 1. When a new sample is added to m_lFree call NotifySample() which
- calls ReleaseSemaphore on m_hSem with a count of m_lWaiting and
- sets m_lWaiting to 0.
- This must all be done holding the allocator's critical section.
-
- 2. When waiting for a sample call SetWaiting() which increments
- m_lWaiting BEFORE leaving the allocator's critical section.
-
- 3. Actually wait by calling WaitForSingleObject(m_hSem, INFINITE)
- having left the allocator's critical section. The effect of
- this is to remove 1 from the semaphore's count. You MUST call
- this once having incremented m_lWaiting.
-
- The following are then true when the critical section is not held :
- (let nWaiting = number about to wait or waiting)
-
- (1) if (m_lFree.GetCount() != 0) then (m_lWaiting == 0)
- (2) m_lWaiting + Semaphore count == nWaiting
-
- We would deadlock if
- nWaiting != 0 &&
- m_lFree.GetCount() != 0 &&
- Semaphore count == 0
-
- But from (1) if m_lFree.GetCount() != 0 then m_lWaiting == 0 so
- from (2) Semaphore count == nWaiting (which is non-0) so the
- deadlock can't happen.

-/* This class implements a simple cache. A cache object is instantiated

- object derived from CBaseObject (helps reduce memory leaks). The cache
- can then have objects added to it and removed from it. The cache size
- is fixed at construction time and may therefore run out or be flooded.
- If it runs out it returns a NULL pointer, if it fills up it also returns
- a NULL pointer instead of a pointer to the object just inserted */

-/* WARNING Be very careful when using this class, what it lets you do is
- store and retrieve objects so that you can minimise object creation
- which in turns improves efficiency. However the object you store is
- exactly the same as the object you get back which means that it short
- circuits the constructor initialisation phase. This means any class
- variables the object has (eg pointers) are highly likely to be invalid.
- Therefore ensure you reinitialise the object before using it again */

-/*
-
-a. Derive your COM object from CUnknown
-
-b. Make a static CreateInstance function that takes an LPUNKNOWN, an HRESULT *
- and a TCHAR *. The LPUNKNOWN defines the object to delegate IUnknown calls
- to. The HRESULT * allows error codes to be passed around constructors and
- the TCHAR * is a descriptive name that can be printed on the debugger.
-
- It is important that constructors only change the HRESULT * if they have
- to set an ERROR code, if it was successful then leave it alone or you may
- overwrite an error code from an object previously created.
-
- When you call a constructor the descriptive name should be in static store
- as we do not copy the string. To stop large amounts of memory being used
- in retail builds by all these static strings use the NAME macro,
-
- CMyFilter = new CImplFilter(NAME("My filter"),pUnknown,phr);
- if (FAILED(hr)) {
- return hr;
- }
-
- In retail builds NAME(_x_) compiles to NULL, the base CBaseObject class
- knows not to do anything with objects that don't have a name.
-
-c. Have a constructor for your object that passes the LPUNKNOWN, HRESULT * and
- TCHAR * to the CUnknown constructor. You can set the HRESULT if you have an
- error, or just simply pass it through to the constructor.
-
- The object creation will fail in the class factory if the HRESULT indicates
- an error (ie FAILED(HRESULT) == TRUE)
-
-d. Create a FactoryTemplate with your object's class id and CreateInstance
- function.
-
-Then (for each interface) either
-
-Multiple inheritance
-
-1. Also derive it from ISomeInterface
-2. Include DECLARE_IUNKNOWN in your class definition to declare
- implementations of QueryInterface, AddRef and Release that
- call the outer unknown
-3. Override NonDelegatingQueryInterface to expose ISomeInterface by
- code something like
-
- if (riid == IID_ISomeInterface) {
- return GetInterface((ISomeInterface *) this, ppv);
- } else {
- return CUnknown::NonDelegatingQueryInterface(riid, ppv);
- }
-
-4. Declare and implement the member functions of ISomeInterface.
-
-or: Nested interfaces
-
-1. Declare a class derived from CUnknown
-2. Include DECLARE_IUNKNOWN in your class definition
-3. Override NonDelegatingQueryInterface to expose ISomeInterface by
- code something like
-
- if (riid == IID_ISomeInterface) {
- return GetInterface((ISomeInterface *) this, ppv);
- } else {
- return CUnknown::NonDelegatingQueryInterface(riid, ppv);
- }
-
-4. Implement the member functions of ISomeInterface. Use GetOwner() to
- access the COM object class.
-
-And in your COM object class:
-
-5. Make the nested class a friend of the COM object class, and declare
- an instance of the nested class as a member of the COM object class.
-
- NOTE that because you must always pass the outer unknown and an hResult
- to the CUnknown constructor you cannot use a default constructor, in
- other words you will have to make the member variable a pointer to the
- class and make a NEW call in your constructor to actually create it.
-
-6. override the NonDelegatingQueryInterface with code like this:
-
- if (riid == IID_ISomeInterface) {
- return m_pImplFilter->
- NonDelegatingQueryInterface(IID_ISomeInterface, ppv);
- } else {
- return CUnknown::NonDelegatingQueryInterface(riid, ppv);
- }
-
-You can have mixed classes which support some interfaces via multiple
-inheritance and some via nested classes

-// Base property page class. Filters typically expose custom properties by
-// implementing special control interfaces, examples are IDirectDrawVideo
-// and IQualProp on renderers. This allows property pages to be built that
-// use the given interface. Applications such as the ActiveMovie OCX query
-// filters for the property pages they support and expose them to the user
-//
-// This class provides all the framework for a property page. A property
-// page is a COM object that supports IPropertyPage. We should be created
-// with a resource ID for the dialog which we will load when required. We
-// should also be given in the constructor a resource ID for a title string
-// we will load from the DLLs STRINGTABLE. The property page titles must be
-// stored in resource files so that they can be easily internationalised
-//
-// We have a number of virtual methods (not PURE) that may be overriden in
-// derived classes to query for interfaces and so on. These functions have
-// simple implementations here that just return NOERROR. Derived classes
-// will almost definately have to override the message handler method called
-// OnReceiveMessage. We have a static dialog procedure that calls the method
-// so that derived classes don't have to fiddle around with the this pointer

- // if the handle is set there will be a command ready. Each time the

-
- WHAT IT MEANS:
- The log shows what happened and when. Each line shows the time at which
- something happened (see WHAT YOU CODE below) what it was that happened
- and (if approporate) the time since the corresponding previous event
- (that's the delta column).
-
- The statistics show how many times each event occurred, what the average
- delta time was, also the standard deviation, largest and smalles delta.
-
- WHAT YOU CODE:
-
- Before anything else executes: - register your ids
-
- int id1 = Msr_Register("Incident One - Note");
- int id2 = Msr_Register("Incident Two - Start/Stop");
- int id3 = Msr_Register("Incident Three - single Note");
- etc.
-
- At interesting moments:
-
- // To measure a repetitive event - e.g. end of bitblt to screen
- Msr_Note(Id9); // e.g. "video frame hiting the screen NOW!"
-
- or
-
- // To measure an elapsed time e.g. time taken to decode an MPEG B-frame
- Msr_Start(Id2); // e.g. "Starting to decode MPEG B-frame"
- . . .
- MsrStop(Id2); // "Finished MPEG decode"
-
- At the end:
-
- HANDLE hFile;
- hFile = CreateFile("Perf.log", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, 0, NULL);
- Msr_Dump(hFile); // This writes the log out to the file
- CloseHandle(hFile);
-
- or
-
- Msr_Dump(NULL); // This writes it to DbgLog((LOG_TRACE,0, ... ));
- // but if you are writing it out to the debugger
- // then the times are probably all garbage because
- // the debugger can make things run awfully slow.
-
- A given id should be used either for start / stop or Note calls. If Notes
- are mixed in with Starts and Stops their statistics will be gibberish.
-
- If you code the calls in upper case i.e. MSR_START(idMunge); then you get
- macros which will turn into nothing unless PERF is defined.
-
- You can reset the statistical counts for a given id by calling Reset(Id).
- They are reset by default at the start.
- It logs Reset as a special incident, so you can see it in the log.
-
- The log is a circular buffer in storage (to try to minimise disk I/O).
- It overwrites the oldest entries once full. The statistics include ALL
- incidents since the last Reset, whether still visible in the log or not.

-
-// Base class for persistent properties of filters
-// (i.e. filter properties in saved graphs)
-
-// The simplest way to use this is:
-// 1. Arrange for your filter to inherit this class
-// 2. Implement in your class WriteToStream and ReadFromStream
-// These will override the "do nothing" functions here.
-// 3. Change your NonDelegatingQueryInterface to handle IPersistStream
-// 4. Implement SizeMax to return the number of bytes of data you save.
-// If you save UNICODE data, don't forget a char is 2 bytes.
-// 5. Whenever your data changes, call SetDirty()
-//
-// At some point you may decide to alter, or extend the format of your data.
-// At that point you will wish that you had a version number in all the old
-// saved graphs, so that you can tell, when you read them, whether they
-// represent the old or new form. To assist you in this, this class
-// writes and reads a version number.
-// When it writes, it calls GetSoftwareVersion() to enquire what version
-// of the software we have at the moment. (In effect this is a version number
-// of the data layout in the file). It writes this as the first thing in the data.
-// If you want to change the version, implement (override) GetSoftwareVersion().
-// It reads this from the file into mPS_dwFileVersion before calling ReadFromStream,
-// so in ReadFromStream you can check mPS_dwFileVersion to see if you are reading
-// an old version file.
-// Normally you should accept files whose version is no newer than the software
-// version that's reading them.

- * During class construction we create a worker thread that is destroyed during

- * is reached. The wakeup points are determined by clients making Advise
- * calls.
- *
- * Each advise call defines a point in time when they wish to be notified. A
- * periodic advise is a series of these such events. We maintain a list of
- * advise links and calculate when the nearest event notification is due for.
- * We then call WaitForSingleObject with a timeout equal to this time. The
- * handle we wait on is used by the class to signal that something has changed
- * and that we must reschedule the next event. This typically happens when
- * someone comes in and asks for an advise link while we are waiting for an
- * event to timeout.
- *
- * While we are modifying the list of advise requests we
- * are protected from interference through a critical section. Clients are NOT
- * advised through callbacks. One shot clients have an event set, while
- * periodic clients have a semaphore released for each event notification. A
- * semaphore allows a client to be kept up to date with the number of events

-
-
-// How allocators are decided.
-//
-// An in-place transform tries to do its work in someone else's buffers.
-// It tries to persuade the filters on either side to use the same allocator
-// (and for that matter the same media type). In desperation, if the downstream
-// filter refuses to supply an allocator and the upstream filter offers only
-// a read-only one then it will provide an allocator.
-// if the upstream filter insists on a read-only allocator then the transform
-// filter will (reluctantly) copy the data before transforming it.
-//
-// In order to pass an allocator through it needs to remember the one it got
-// from the first connection to pass it on to the second one.
-//
-// It is good if we can avoid insisting on a particular order of connection
-// (There is a precedent for insisting on the input
-// being connected first. Insisting on the output being connected first is
-// not allowed. That would break RenderFile.)
-//
-// The base pin classes (CBaseOutputPin and CBaseInputPin) both have a
-// m_pAllocator member which is used in places like
-// CBaseOutputPin::GetDeliveryBuffer and CBaseInputPin::Inactive.
-// To avoid lots of extra overriding, we should keep these happy
-// by using these pointers.
-//
-// When each pin is connected, it will set the corresponding m_pAllocator
-// and will have a single ref-count on that allocator.
-//
-// Refcounts are acquired by GetAllocator calls which return AddReffed
-// allocators and are released in one of:
-// CBaseInputPin::Disconnect
-// CBaseOutputPin::BreakConect
-// In each case m_pAllocator is set to NULL after the release, so this
-// is the last chance to ever release it. If there should ever be
-// multiple refcounts associated with the same pointer, this had better
-// be cleared up before that happens. To avoid such problems, we'll
-// stick with one per pointer.
-
-
-
-// RECONNECTING and STATE CHANGES
-//
-// Each pin could be disconnected, connected with a read-only allocator,
-// connected with an upstream read/write allocator, connected with an
-// allocator from downstream or connected with its own allocator.
-// Five states for each pin gives a data space of 25 states.
-//
-// Notation:
-//
-// R/W == read/write
-// R-O == read-only
-//
-// <input pin state> <output pin state> <comments>
-//
-// 00 means an unconnected pin.
-// <- means using a R/W allocator from the upstream filter
-// <= means using a R-O allocator from an upstream filter
-// || means using our own (R/W) allocator.
-// -> means using a R/W allocator from a downstream filter
-// (a R-O allocator from downstream is nonsense, it can't ever work).
-//
-//
-// That makes 25 possible states. Some states are nonsense (two different
-// allocators from the same place). These are just an artifact of the notation.
-// <= <- Nonsense.
-// <- <= Nonsense
-// Some states are illegal (the output pin never accepts a R-O allocator):
-// 00 <= !! Error !!
-// <= <= !! Error !!
-// || <= !! Error !!
-// -> <= !! Error !!
-// Three states appears to be inaccessible:
-// -> || Inaccessible
-// || -> Inaccessible
-// || <- Inaccessible
-// Some states only ever occur as intermediates with a pending reconnect which
-// is guaranteed to finish in another state.
-// -> 00 ?? unstable goes to || 00
-// 00 <- ?? unstable goes to 00 ||
-// -> <- ?? unstable goes to -> ->
-// <- || ?? unstable goes to <- <-
-// <- -> ?? unstable goes to <- <-
-// And that leaves 11 possible resting states:
-// 1 00 00 Nothing connected.
-// 2 <- 00 Input pin connected.
-// 3 <= 00 Input pin connected using R-O allocator.
-// 4 || 00 Needs several state changes to get here.
-// 5 00 || Output pin connected using our allocator
-// 6 00 -> Downstream only connected
-// 7 || || Undesirable but can be forced upon us.

-// 11 -> -> Transform in place (ideal)

-// The object of the exercise is to ensure that we finish up in states
-// 10 or 11 whenever possible. State 10 is only possible if the upstream
-// filter has a R/W allocator (the AVI splitter notoriously
-// doesn't) and state 11 is only possible if the downstream filter does
-// offer an allocator.
-//
-// The transition table (entries marked * go via a reconnect)
-//
-// There are 8 possible transitions:
-// A: Connect upstream to filter with R-O allocator that insists on using it.
-// B: Connect upstream to filter with R-O allocator but chooses not to use it.
-// C: Connect upstream to filter with R/W allocator and insists on using it.
-// D: Connect upstream to filter with R/W allocator but chooses not to use it.
-// E: Connect downstream to a filter that offers an allocator
-// F: Connect downstream to a filter that does not offer an allocator
-// G: disconnect upstream
-// H: Disconnect downstream
-//

-//
-// All these states are accessible without requiring any filter to
-// change its behaviour but not all transitions are accessible, for
-// instance a transition from state 4 to anywhere other than
-// state 8 requires that the upstream filter first offer a R-O allocator
-// and then changes its mind and offer R/W. This is NOT allowable - it
-// leads to things like the output pin getting a R/W allocator from
-// upstream and then the input pin being told it can only have a R-O one.
-// Note that you CAN change (say) the upstream filter for a different one, but
-// only as a disconnect / connect, not as a Reconnect. (Exercise for
-// the reader is to see how you get into state 4).
-//
-// The reconnection stuff goes as follows (some of the cases shown here as
-// "no reconnect" may get one to finalise media type - an old story).
-// If there is a reconnect where it says "no reconnect" here then the
-// reconnection must not change the allocator choice.
-//
-// state 2: <- 00 transition E <- <- case C <- <- (no change)
-// case D -> <- and then to -> ->
-//
-// state 2: <- 00 transition F <- <- (no reconnect)
-//
-// state 3: <= 00 transition E <= -> case A <= -> (no change)
-// case B -> ->
-// transition F <= || case A <= || (no change)
-// case B || ||
-//
-// state 4: || 00 transition E || || case B -> || and then all cases to -> ->
-// F || || case B || || (no change)
-//
-// state 5: 00 || transition A <= || (no reconnect)
-// B || || (no reconnect)
-// C <- || all cases <- <-
-// D || || (unfortunate, but upstream's choice)
-//
-// state 6: 00 -> transition A <= -> (no reconnect)
-// B -> -> (no reconnect)
-// C <- -> all cases <- <-
-// D -> -> (no reconnect)
-//
-// state 10:<- <- transition G 00 <- case E 00 ->
-// case F 00 ||
-//
-// state 11:-> -> transition H -> 00 case A <= 00 (schizo)
-// case B <= 00
-// case C <- 00 (schizo)
-// case D <- 00
-//
-// The Rules:
-// To sort out media types:
-// The input is reconnected
-// if the input pin is connected and the output pin connects
-// The output is reconnected
-// If the output pin is connected
-// and the input pin connects to a different media type
-//
-// To sort out allocators:
-// The input is reconnected
-// if the output disconnects and the input was using a downstream allocator
-// The output pin calls SetAllocator to pass on a new allocator
-// if the output is connected and
-// if the input disconnects and the output was using an upstream allocator
-// if the input acquires an allocator different from the output one
-// and that new allocator is not R-O
-//
-// Data is copied (i.e. call getbuffer and copy the data before transforming it)
-// if the two allocators are different.
-
-
-
-// CHAINS of filters:
-//
-// We sit between two filters (call them A and Z). We should finish up
-// with the same allocator on both of our pins and that should be the
-// same one that A and Z would have agreed on if we hadn't been in the
-// way. Furthermore, it should not matter how many in-place transforms
-// are in the way. Let B, C, D... be in-place transforms ("us").
-// Here's how it goes:
-//
-// 1.
-// A connects to B. They agree on A's allocator.
-// A-a->B
-//
-// 2.
-// B connects to C. Same story. There is no point in a reconnect, but
-// B will request an input reconnect anyway.
-// A-a->B-a->C
-//
-// 3.
-// C connects to Z.
-// C insists on using A's allocator, but compromises by requesting a reconnect.
-// of C's input.
-// A-a->B-?->C-a->Z
-//
-// We now have pending reconnects on both A--->B and B--->C
-//
-// 4.
-// The A--->B link is reconnected.
-// A asks B for an allocator. B sees that it has a downstream connection so
-// asks its downstream input pin i.e. C's input pin for an allocator. C sees
-// that it too has a downstream connection so asks Z for an allocator.
-//
-// Even though Z's input pin is connected, it is being asked for an allocator.
-// It could refuse, in which case the chain is done and will use A's allocator
-// Alternatively, Z may supply one. A chooses either Z's or A's own one.
-// B's input pin gets NotifyAllocator called to tell it the decision and it
-// propagates this downstream by calling ReceiveAllocator on its output pin
-// which calls NotifyAllocator on the next input pin downstream etc.
-// If the choice is Z then it goes:
-// A-z->B-a->C-a->Z
-// A-z->B-z->C-a->Z
-// A-z->B-z->C-z->Z
-//
-// And that's IT!! Any further (essentially spurious) reconnects peter out
-// with no change in the chain.

- // Frames are assumed to come in three types:
- // Type 1: an AVI key frame or an MPEG I frame.
- // This frame can be decoded with no history.
- // Dropping this frame means that no further frame can be decoded
- // until the next type 1 frame.
- // Type 1 frames are sync points.
- // Type 2: an AVI non-key frame or an MPEG P frame.
- // This frame cannot be decoded unless the previous type 1 frame was
- // decoded and all type 2 frames since have been decoded.
- // Dropping this frame means that no further frame can be decoded
- // until the next type 1 frame.
- // Type 3: An MPEG B frame.
- // This frame cannot be decoded unless the previous type 1 or 2 frame
- // has been decoded AND the subsequent type 1 or 2 frame has also
- // been decoded. (This requires decoding the frames out of sequence).
- // Dropping this frame affects no other frames. This implementation
- // does not allow for these. All non-sync-point frames are treated
- // as being type 2.
- //
- // The spacing of frames of type 1 in a file is not guaranteed. There MUST
- // be a type 1 frame at (well, near) the start of the file in order to start
- // decoding at all. After that there could be one every half second or so,
- // there could be one at the start of each scene (aka "cut", "shot") or
- // there could be no more at all.
- // If there is only a single type 1 frame then NO FRAMES CAN BE DROPPED
- // without losing all the rest of the movie. There is no way to tell whether
- // this is the case, so we find that we are in the gambling business.

- // that we have seen and we bet on things being no worse than this in the
- // future.

-
-// This library provides fairly straight forward debugging functionality, this
-// is split into two main sections. The first is assertion handling, there are
-// three types of assertions provided here. The most commonly used one is the
-// ASSERT(condition) macro which will pop up a message box including the file
-// and line number if the condition evaluates to FALSE. Then there is the
-// EXECUTE_ASSERT macro which is the same as ASSERT except the condition will
-// still be executed in NON debug builds. The final type of assertion is the
-// KASSERT macro which is more suitable for pure (perhaps kernel) filters as
-// the condition is printed onto the debugger rather than in a message box.
-//
-// The other part of the debug module facilties is general purpose logging.
-// This is accessed by calling DbgLog(). The function takes a type and level
-// field which define the type of informational string you are presenting and
-// it's relative importance. The type field can be a combination (one or more)
-// of LOG_TIMING, LOG_TRACE, LOG_MEMORY, LOG_LOCKING and LOG_ERROR. The level
-// is a DWORD value where zero defines highest important. Use of zero as the
-// debug logging level is to be encouraged ONLY for major errors or events as
-// they will ALWAYS be displayed on the debugger. Other debug output has it's
-// level matched against the current debug output level stored in the registry
-// for this module and if less than the current setting it will be displayed.
-//
-// Each module or executable has it's own debug output level for each of the
-// five types. These are read in when the DbgInitialise function is called
-// for DLLs linking to STRMBASE.LIB this is done automatically when the DLL
-// is loaded, executables must call it explicitely with the module instance
-// handle given to them through the WINMAIN entry point. An executable must
-// also call DbgTerminate when they have finished to clean up the resources
-// the debug library uses, once again this is done automatically for DLLs

-
-/* A generic list of pointers to objects.
- Objectives: avoid using MFC libraries in ndm kernel mode and
- provide a really useful list type.
-
- The class is thread safe in that separate threads may add and
- delete items in the list concurrently although the application
- must ensure that constructor and destructor access is suitably
- synchronised.
-
- The list name must not conflict with MFC classes as an
- application may use both
-
- The nodes form a doubly linked, NULL terminated chain with an anchor
- block (the list object per se) holding pointers to the first and last
- nodes and a count of the nodes.
- There is a node cache to reduce the allocation and freeing overhead.
- It optionally (determined at construction time) has an Event which is
- set whenever the list becomes non-empty and reset whenever it becomes
- empty.
- It optionally (determined at construction time) has a Critical Section
- which is entered during the important part of each operation. (About
- all you can do outside it is some parameter checking).
-
- The node cache is a repository of nodes that are NOT in the list to speed
- up storage allocation. Each list has its own cache to reduce locking and
- serialising. The list accesses are serialised anyway for a given list - a
- common cache would mean that we would have to separately serialise access
- of all lists within the cache. Because the cache only stores nodes that are
- not in the list, releasing the cache does not release any list nodes. This
- means that list nodes can be copied or rechained from one list to another
- without danger of creating a dangling reference if the original cache goes
- away.
-
- Questionable design decisions:
- 1. Retaining the warts for compatibility
- 2. Keeping an element count -i.e. counting whenever we do anything
- instead of only when we want the count.
- 3. Making the chain pointers NULL terminated. If the list object
- itself looks just like a node and the list is kept as a ring then
- it reduces the number of special cases. All inserts look the same.

- synchronised. An application can cause deadlock with operations
- which use two lists by simultaneously calling

- are n+1 places to insert and NULL is that "n+1-th" value).
- The POSITION of an element in the list is only invalidated if

- (symmetrically if you are working backwards through the list).
- 3. It simplifies the algebra which the methods generate.
