Detailed Description

An encapsulation of a DirectShow graph (Windows-specific).

Constructor & Destructor Documentation

DirectShowGraph()

ts::DirectShowGraph::DirectShowGraph

(

)

Default constructor.

~DirectShowGraph()

virtual ts::DirectShowGraph::~DirectShowGraph ( )

virtual

Destructor.

Member Function Documentation

initialize()

bool ts::DirectShowGraph::initialize

(

Report &

report

)

Initialize the graph.

Parameters

[in,out]

report

Where to report errors.

Returns

True on success, false on error.

clear()

virtual void ts::DirectShowGraph::clear ( Report & report )

virtual

Clear the graph back to uninitialized state.

Parameters

[in,out]

report

Where to report errors.

Reimplemented in ts::TunerGraph.

isValid()

bool ts::DirectShowGraph::isValid

(

)

const

Check if the graph was correctly initialized.

Returns

True if the graph was correctly initialized.

addFilter()

bool ts::DirectShowGraph::addFilter	(	::IBaseFilter *	filter,
		const wchar_t *	name,
		Report &	report )

Add a filter in the graph.

Parameters

[in,out]	filter	The filter to add.
[in]	name	Filter name.
[in,out]	report	Where to report errors.

Returns

True on success, false on error.

removeFilter()

bool ts::DirectShowGraph::removeFilter	(	::IBaseFilter *	filter,
		Report &	report )

Remove a filter from the graph.

Parameters

[in,out]	filter	The filter to remove.
[in,out]	report	Where to report errors.

Returns

True on success, false on error.

connectFilters()

bool ts::DirectShowGraph::connectFilters	(	::IBaseFilter *	filter1,
		::IBaseFilter *	filter2,
		Report &	report )

Directly connect two filters using whatever output and input pin.

Parameters

[in,out]	filter1	DirectShow filter with output pins.
[in,out]	filter2	DirectShow filter with input pins.
[in,out]	report	Where to report errors.

Returns

True on success, false on error.

cleanupDownstream()

bool ts::DirectShowGraph::cleanupDownstream	(	::IBaseFilter *	filter,
		Report &	report )

In the graph, cleanup everything downstream a specified filter. All downstream filters are disconnected and removed from the graph.

Parameters

[in,out]	filter	DirectShow filter.
[in,out]	report	Where to report errors.

Returns

True on success, false on error.

startingFilter()

ComPtr<::IBaseFilter > ts::DirectShowGraph::startingFilter

(

Report &

report

)

Get the starting filter of the graph.

Parameters

[in,out]

report

Where to report errors.

Returns

A pointer to the first filter with no connected input pin or a null pointer if not found.

run()

bool ts::DirectShowGraph::run

(

Report &

report

)

Run the graph.

Parameters

[in,out]

report

Where to report errors.

Returns

True on success, false on error.

stop()

bool ts::DirectShowGraph::stop

(

Report &

report

)

Stop the graph.

Parameters

[in,out]

report

Where to report errors.

Returns

True on success or already stopped, false on error.

display()

void ts::DirectShowGraph::display	(	std::ostream &	output,
		Report &	report,
		const UString &	margin = UString(),
		bool	verbose = true )

Display the description of the graph.

Parameters

[in,out]	output	Where to display test results.
[in,out]	report	Where to report errors.
[in]	margin	Left margin to display.
[in]	verbose	True for verbose information.
