Using the multimedia players in DeBoard is
easy but you should be aware of a few facts
when dealing with your computer's capacity.
Scrolling, moving images and crawl lines will
take precedence over playing multimedia
files. If you are playing a long wave file (30
seconds to 30 minutes), and the movement
processes are choking the wave file's output
(stuttering, etc.), increase the delay in the
movement processes to give the multimedia
player more time to read or buffer the wave
file. When you adjust the delay, you are
balancing the time allotted to both the wave
player and the scrolling engines. This applies
to AVI files as well. Midi files on the other
hand, use very little file I-O and usually won't
slow your system down but can play havoc
on system timing.
You can, if your computer has the
horsepower, play a wave file or Midi file and
an multiple AVI files and scroll text at the
same time! We've tested and verified this
using the 640 by 480 256-color mode,
running NT5.0 on 133 MHz Pentium 24 meg
machine without problems. W9x however
didn't do so well. Playing multiple full screen
multimedia with audio requires near perfect
conditions to be effective.
