Constructor & Destructor Documentation

makVrv::DtProcessImageTask::DtProcessImageTask	(	DtDe &	de,
		const DtVideoStream &	stream
	)

CTOR.

virtual makVrv::DtProcessImageTask::~DtProcessImageTask ( )

virtual

DTOR.

makVrv::DtProcessImageTask::DtProcessImageTask ( )

private

This method is executed in a loop by the worker thread created when the image task is initialized. It runs all the process image task elements.

Default CTOR (unimplemented)

makVrv::DtProcessImageTask::DtProcessImageTask ( const DtProcessImageTask & orig )

private

Copy CTOR (unimplemented)

Member Function Documentation

virtual bool makVrv::DtProcessImageTask::initialize	(	const makArchives::DtVideoStreamRecord::ImageTaskRecords &	taskList,
		const makArchives::DtMetadataPublisherRecord &	metadataConfig
	)

virtual

Provide the image task with all the configuration data necessary to create the image task element pipeline and metadata publisher.

virtual void makVrv::DtProcessImageTask::process	(	const DtReadFramebufferProcessData &	data,
		bool	tickPublisher
	)

virtual

Ticks the metadata publisher, if tickPublisher is true -tickPublisher is false when HW encoding, because the process is called asynchronously from another thread (when the encoded frame is ready). Therefore, the client needs to call DtProcessImageTask::tickMetaDataPublisher on its own beforehand, in this case -tickPublisher is true otherwise. Then, it pushes the captured image onto the image processing queue (where it can be modified/operated on by the image task elements)

virtual void makVrv::DtProcessImageTask::tickMetaDataPublisher ( void )

virtual

explicitly tick. Used when async hw encoding done in another thread Needs to be done before frame is submitted to the encoder

const DtVideoStream& makVrv::DtProcessImageTask::stream ( )

Get the video stream process image task is supporting.

virtual DtImageTaskElement* makVrv::DtProcessImageTask::buildPipeline ( const makArchives::DtVideoStreamRecord::ImageTaskRecords & taskList )

protectedvirtual

Create all the process image task elements specified in the ImageTaskRecords record.

virtual void makVrv::DtProcessImageTask::setElementFromRecord	(	DtImageTaskElement *	element,
		const makArchives::DtImageTaskRecord &	taskRecord
	)

protectedvirtual

Initialize a process image task element from the DtImageTaskRecord which caused its creation in buildPipeline.

virtual bool makVrv::DtProcessImageTask::configureElement ( DtImageTaskElement * element )

protectedvirtual

Configure a process image task element based on its current initialization state.

DtProcessImageTask& makVrv::DtProcessImageTask::operator= ( const DtProcessImageTask & rhs )

private

Assignment operator (unimplemented)

virtual void makVrv::DtProcessImageTask::run ( )

privatevirtual

Function that will be called when the worker thread is started.
