IMVSCSelectInput

The IMVSCSelectInput Interface Interface from the MontiVision Smart Control  provides methods to select the physical input from a capture source crossbar with multiple physical input ports. The  MV SelectInputComboBox uses this interface.

Methods:

Typelib: MV SMartCOntrol

Method IMVSCSelectInput::CheckConnection

Declaration: Sub CheckConnection(SourceFilter As String, Input As Long, Output As Long)

Check if a connection between an input and output pin is possible. The method returns S_OK (0) if the connection is possible or S_FALSE (1) if no connection between the two pins is possible.

Parameter:

	SourceFilter	Source filter label within the filter graph configuration.
	Input	Input pin index.
	Output	Output pin index.

Prototype:

HRESULT CheckConnection(BSTR SourceFilter, LONG Input, LONG Output);

Method IMVSCSelectInput::Connect

Declaration: Sub Connect(SourceFilter As String, Input As Long, Output As Long)

Connects a input to an output from a crossbar.

Parameter:

	SourceFilter	Source filter label within the filter graph configuration.
	Input	Input pin index.
	Output	Output pin index.

Prototype:

HRESULT Connect(STRING SourceFilter, LONG Input, LONG Output);

Method IMVSCSelectInput::CurrentConnection

Declaration: Function CurrentConnection(SourceFilter As String, Output As Long) As Long

Get the current connected input pin for an output pin. It returns the index from the current connected input pin.

Parameter:

	SourceFilter	Source filter label within the filter graph configuration.
	Output	Output pin index.

Prototype:

HRESULT CurrentConnection(BSTR SourceFilter, LONG Output, LONG* value);

Method IMVSCSelectInput::GetInputLabel

Declaration: Function GetInputLabel(SourceFilter As String, Index As Long) As String

Get the label from a output pin.

Parameter:

	SourceFilter	Source filter label within the filter graph configuration.
	Index	Input pin index.

Prototype:

HRESULT GetInputLabel(BSTR SourceFilter, LONG Index, BSTR* value);

Method IMVSCSelectInput::GetOutputLabel

Declaration: Function GetOutputLabel(SourceFilter As String, Index As Long) As String

Get the label from a output pin.

Parameter:

	SourceFilter	Source filter label within the filter graph configuration.
	Index	Output pin index.

Prototype:

HRESULT GetOutputLabel(BSTR SourceFilter, LONG Index, BSTR* value);

Method IMVSCSelectInput::InputCount

Declaration: Function InputCount(SourceFilter As String) As Long

Get the input pin count from the crossbar of a video source filter.

Parameter:

SourceFilter

Source filter label within the filter graph configuration.

Prototype:

HRESULT InputCount(BSTR SourceFilter, LONG* value);

Method IMVSCSelectInput::IsAvailable

Declaration: Function IsAvailable(SourceFilter As String) As Boolean

Test if the crossbar is available

Parameter:

SourceFilter

Source filter label within the filter graph configuration.

Prototype:

HRESULT IsAvailable(BSTR SourceFilter, BOOL* value);

Method IMVSCSelectInput::OutputCount

Declaration: Function OutputCount(SourceFilter As String) As Long

Get the output pin count from a crossbar og a video source filter.

Parameter:

SourceFilter

Source filter label within the filter graph configuration.

Prototype:

HRESULT OutputCount(BSTR SourceFilter, LONG* value);
