◆ getStatusString()

QString cx::BasicVideoSource::getStatusString ( ) const
virtual

status text describing the stream state, display instead of stream when the stream is invalid.

Implements cx::VideoSource.

virtual

Implements cx::VideoSource.

Definition at line 114 of file cxBasicVideoSource.cpp.

◆ isConnected()

bool cx::BasicVideoSource::isConnected ( ) const
virtual

return true when a connection to the data source is established.

Implements cx::VideoSource.

Definition at line 99 of file cxBasicVideoSource.cpp.

◆ isStreaming()

bool cx::BasicVideoSource::isStreaming ( ) const
virtual

return true when the source is streaming data.

Implements cx::VideoSource.

Definition at line 104 of file cxBasicVideoSource.cpp.

◆ overrideTimeout()

void cx::BasicVideoSource::overrideTimeout ( bool  timeout)

Disable internal timeout checking, instead set timeout directly.

Definition at line 53 of file cxBasicVideoSource.cpp.

◆ setInfoString()

void cx::BasicVideoSource::setInfoString ( QString  text)
inline

Definition at line 83 of file cxBasicVideoSource.h.

◆ setInput()

void cx::BasicVideoSource::setInput ( ImagePtr  input)

Set an image that is used for output.

Set a new image for each new frame. Only the vtkImageData, uid and timestamp are used, also make sure the uid is unchanged for each setInput().

Setting an input indicates connect(), settings an empty input indicates disconnect()
