The video client

can be started as follows:
# xvideo [-<option>]
After
xvideo
is started two windows show up: the
control panel
and the
canvas panel
. The control panel of-
fers controls for customizing the display. Whereas the canvas panel displays the video or RGB data. The video
client detects automatically what kind of signal is connected to channel 1.

depending on the actual hardware configuration of your E

.
The options for starting the video client
xvideo
are listed in section
. An important option is
described below: Module Video and Module RGB.
Module video and Module RGB
All input cards allow to start the video client
xvideo
with an option for displaying the input signal without
borders and fitted to complete projection modules (1 to n×n, depending on configuration).
The command
# xvideo –mv 1 –mg 1x1+1+0
lets the video client start as Module Video (
-mv 1
) on the second cube from the left in the upper row (
-mg
1x1+1+0
).
The displayed video or RGB signal is always »on top«, other applications are »beyond« and can not be manipu-
lated by accident.
