GUI Application (vcu_qt)
The vcu_qt application is a multi-threaded Linux application that uses the Qt graphics
toolkit to render a GUI. The GUI provides control knobs for user input and a display area to
show the captured video stream. The GUI shown in Figure 3-9 contains the following
control elements displayed on top of the video output area:
• Control bar (top)
• Video info panel (top-right)
• System performance panels (bottom)
Number of Inputs
This determines the number of active video sources. In the current version of the TRD, a
maximum of four sources are supported (the default value is one).
See Figure 3-10 for input settings.
