Member Function Documentation

abortStream()

void jevois::VideoDisplayGUI::abortStream ( )

overridevirtual

Abort streaming.

This only cancels future get() and done() calls, one should still call streamOff() to turn off streaming.

Implements jevois::VideoOutput.

Definition at line 116 of file VideoDisplayGUI.C.

get()

void jevois::VideoDisplayGUI::get ( jevois::RawImage &  img )

overridevirtual

Get a pre-allocated image so that we can fill the pixel data and later send out using send()

Implements jevois::VideoOutput.

Definition at line 78 of file VideoDisplayGUI.C.

References jevois::RawImage::bufindex, LDEBUG, and LFATAL.

send()

void jevois::VideoDisplayGUI::send ( jevois::RawImage const &  img )

overridevirtual

Send an image out to display.

Implements jevois::VideoOutput.

Definition at line 88 of file VideoDisplayGUI.C.

References jevois::RawImage::bufindex, h, LDEBUG, and LFATAL.

setFormat()

void jevois::VideoDisplayGUI::setFormat ( jevois::VideoMapping const &  m )

overridevirtual

Set the video format and frame rate, allocate the buffers.

Implements jevois::VideoOutput.

streamOff()

void jevois::VideoDisplayGUI::streamOff ( )

overridevirtual

Stop streaming.

Implements jevois::VideoOutput.

Definition at line 120 of file VideoDisplayGUI.C.

streamOn()

void jevois::VideoDisplayGUI::streamOn ( )

overridevirtual

Start streaming.

Implements jevois::VideoOutput.
