Screenshots and work samples
|
Since the Gnome screenshot utility can not grab the content of
overlay buffers only one screenshot for first. You have to
imagine a video image
instead of the blue box on the left. The screenshot gives an
impression of the main GUI elements in version 0.1
of wechselspieler:
Fig. 1: The main GUI elements. Main window (top),
binarisation dialog (botton left),
region/trigger preferences for the
first region, selected in main window
(botton right).
Fig. 2: The main window with configuration
dialogs for each region grouped around it, as in version
0.4.
Those who are curious about what Wechselspieler is good for, a
Quicktime movie (5.2MB) gives an impression of
what can be done with the software. Although it is artistically
not that sophisticated it shows
the key point of wechselspieler: Generating sound from video.
In this case, the waves of the ocean play a simple tune.
