ATTENTION: this
category is for experienced users since it makes call to
system files of MS Windows 95. If your don't have advanced
knowledge of this environment, don't try the manipulations
explained below.
Media Control
Interfacing (MCI) allows a standardized playing of multimedia
files. The Windows Media Player functions thanks to this
library. A MCI driver is a file allowing the playing of one or
several multimedia files. WIN.INI and SYSTEM.INI files
(located in the Windows folder) are used by MCI.
1.
SYSTEM.INI
MCI drivers are declared in the [MCI] section of
SYSTEM.INI
[mci]
cdaudio=mcicda.drv
sequencer=mciseq.drv
waveaudio=mciwave.drv 9
avivideo=mciavi.drv
videodisc=mcipionr.drv
vcr=mcivisca.drv
dmusic=etekmod.drv
MPEGVideo=mciqtz.drv
Animation1=mciaap.drv
Thus, the MCI
driver mciseq.drv will be recognized under the name of "
sequencer ". It allows to play MIDI files. The MCI driver
mciqtz.drv will be recognized under the name of "
MPEGVideo ", it is the pilot of Microsoft ActiveMovie, it
permits the reading of a large number of files: AVI, MOV, MPG,
MP2, MP3 (ActiveMovie v2 only), MID, WAV, etc...
2.
WIN.INI
File types associated to these MCI drivers are
declared in the [mci extensions]section of WIN.INI
[mci
extensions]
mid=Sequencer
rmi=Sequencer
wav=waveaudio
mod=dmusic
avi=MPEGVideo
mov=MPEGVideo
mpg=MPEGVideo
mpeg=MPEGVideo
au=MPEGVideo
snd=MPEGVideo
aif=MPEGVideo
kar=Sequencer
cda=cdaudio
mp3=MPEGVideo
fli=Animation1
flc=Animation1
That means that
the * .mid files will be read thanks to " sequencer
" driver (therefore mciseq.drv), or that CDaudio tracks
(* .cda) will be read thanks to " cdaudio ",
therefore mcicda.drv.
Several MCI
drivers can be able to read a file type. A driver can be
better optimized than another or can allow more
functionalities. For example, a wavefile can be read thanks to
"waveaudio" or thanks to "MPEGVideo".
Concerning ActiveMovie (MPEGVideo), it adds playing speed
variation (slow, accelerated, etc...) but informations
returned by the pilot MCI are less complete
You can use the
MCI Wizard to assign a
driver to a file type. Nevertheless you won't be able to add a
new type of file. According to MCI drivers installed on your
system, you can configure the playing of your multimedia
files. The driver affected to a filetype must exist
effectively. Don't add MOD=dmusic believing that these files
will be read: when a pilot is installed on your system, it
appears in the [MCI] section of your SYSTEM.INI |
