7. EXAMPLE APPLICATION
7.1 Usage Hints
Linux
Mplayer requires the following options to play the 6-channel audio instead of 2-channel: -channels 6 -af
channels=6:6:0:0:1:1:2:4:3:5:4:2:5:3. The first option selects six channels, and the second option
corrects the channel mapping. Mplayer does not determine the output channel mapping automatically.
Also an option like -ao alsa:device=hw=1.0 may be needed to select the USB Audio Device in case the
system has multiple audio devices.
MAC
The MAC system player seems to only play the two-channel mix of a DVD, and can not be configured for multi-
channel sound, as far as we could determine.

Windows 2000Pro, XP, Vista
Windows MediaPlayer should play all the channels and it also processes the channel order information, thus plays
the channels in the right order. Some old third-party DVD player applications only play 2-channel audio.
