public DPIPortBodyC<DataT>
public DPPlayControlBodyC
public DPStreamOpBodyC

DPISPortC input;

Where to get data from.

DPIPlayControlBodyC()

Default constructor.

DPIPlayControlBodyC(const DPISPortC<DataT> & nin,bool nPassEOS = true,UIntT nstart = ((UIntT)),UIntT nend = ((UIntT)))

Constructor.

StringC OpName() const

Op type name.

DataT Get()

Get next piece of data.

bool Get(DataT & buff)

Try and get next piece of data.
If none, return false. else put data into buff.

bool IsGetReady() const

Is some data ready ?
true = yes.

bool IsGetEOS() const

Has the End Of Stream been reached ?
true = yes.

bool Open(const DPISPortC<DataT> & nPort)

Open new video stream.

DListC<DPIPortBaseC> IPorts() const

Input ports.

DListC<DPIPlugBaseC> IPlugs() const

Input plugs.

const DPISPortC<DataT> & Input()

Access input port.

DataT Get()

Get next piece of data.
May block if not ready, or it could throw an DataNotReadyC exception. NB. This function MUST be provided by client class.

bool Get(DataT & buff)

Try and get next piece of data.
This may not NOT block, if no data is ready it will return false, and not set buff. NB. The default version of this function uses the Get() method defined above and so need not be provided by derived classes.

IntT GetArray(SArray1dC<DataT> & data)

Get an array of data from stream.
returns the number of elements succesfully processed. NB. This need NOT be overridden in client classes unless fast handling of arrays of data elements is required.

const type_info & InputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

bool Discard()

Discard the next input datum.

IntT Speed(IntT ninc)

Set increments.
1 == Normal play -1=Reverse play 2=Double speed forward etc..

UIntT Tell() const

Where are we in the stream ?
This gives the number of the NEXT frame that will be processed.

UIntT LastFrame() const

Get number of last frame read.

UIntT Size() const

How long is the stream ?
This is the number of frames in the sequence.

bool Seek(UIntT pos)

Seek to an absolute position in stream

void Pause()

Pause playing.

void Continue()

Continue playing.

void Jog(IntT frames = 1)

Move 'frames' forward or backward.

UIntT FixedStart() const

Get start of sub sequence.

UIntT FixedEnd() const

Get start of sub sequence.

void ToBeginning()

Goto beginning of sequence. (for GUI)

void FastFwd()

Fast forward. (for GUI)

void PlayFwd()

Play forward. (for GUI)

void JogFwd()

Go forward 1 frame. (for GUI)

void Stop()

Stop (for GUI)

void JogBkw()

Go backward 1 frame. (for GUI)

void PlayBkw()

Play backward. (for GUI)

void FastBkw()

Play backward. (for GUI)

void ToEnd()

Goto end of sequence. (for GUI)

void SeekTo(UIntT loc)

Goto position in sequence. (for GUI)

void PlaySubSequence(int mode,UIntT startfrm,UIntT endfrm)

Play a sub-sequence.
0-Once through whole sequence. 1-Once through sub seq. 2-Repeat 3-back and forth.

IntT & SubSeqStart()

Set sub sequence start.

IntT & SubSeqEnd()

Set sub sequence start.

IntT & SubSeqMode()

Set sub sequence start.

bool Open(const DPSeekCtrlC & nCntrl)

Open new video stream.
This assumes the input stream is locked by the calling function.

bool CheckUpdate()

Check state of stream after get.
This assumes the input stream is locked by the calling function.

StringC OpName() const

Op type name.

DListC<DPIPlugBaseC> IPlugs() const
