Introduction to MCI
By Chris Wagg.
Welcome to MCI
MCI (Multi-Media Control Interface) has been around a long time, and has improved much over the years. Yet it goes mostly unexplored by many developers (including me!). This is an attempt to explore its capabilities and limitations without the need for writing code (just yet). See MSDN for a comprehensive list of possible commands.
A basic set of commands seems to work with all multi-media devices and files(and MCI versions): open, play, pause, stop, close, seek. etc. Some of the optional parameters used with these commands, like "repeat", do not work with all files and devices and versions, so this is your chance to test basic commands on multiple platforms and get the quirks out! -).
Beyond the basics are extended MCI commands and vary depending upon the device: resume, cue, freeze, unfreeze, capture, record, save, etc. Extended commands are not excepted by all devices and all MCI versions.
Be aware that some commands don't work with some devices for obvious reasons: sound-only devices like cdaudio, waveaudio, and midi sequencer are simple devices (versus compound - they don't have video), so they don't support palettes and windows and the 'put' command in any form.
On the other hand, some commands, like cue and resume, don't work for "not so obvious" reasons: they were written for certain devices or versions and have no support beyond that. Test these on various devices before using, or use 'capability' first to see if the command is supported.
Although MCI versions seem to be mostly compatible, there are some minor differences. It's difficult to pinpoint all the little details. A major difference is the old version (4x) seems to return the MCI ERROR NUMBER in its string buffer: MMSYSTEM# followed by the message. I guess some people thought that was redundant since the the error number was already being returned. The newer version (5x) avoids returning the error number in the message buffer. Also the textual messages for the same MCI error numbers are worded slightly different between versions.
Below are past conversations with various machines - including some 486's and other boxes with low-grade sound cards. Although those low-grade machines had limits (like no multiple wave-table support), they otherwise seemed to perform admirably! I tried to clean up the textual conversation somewhat, but included some mistakes that maybe you can learn from :-? Try some of these commands on your machine!
P.S If you come up with some unique solutions or innovative conversations (like I can't get my TVCard or Overlay device to work with MCI! What's the trick?), please e-mail them to Chris Wagg. - TIA!
The Conversation Program
Click here to download the MCI conversation program.
Just type in a textual command and the MCI Interface will respond. The typical MCI command syntax is:
Command <device> (parameters...) (notify | wait)
Command - open, play, pause, stop, close, info, status, capability, etc.
<device> - either a file name, an alias, the word "all", a drive letter for a MMedia device (has to be type-d), or a MM device driver signature (waveaudio, avivideo, cdaudio, sequencer, etc.)
(notify | wait) - are optional parameters, and accepted by most MCI commands.
Tip: <Enter> launches the command line. To avoid that, use <Ctrl><Enter>
Notes:
- "All" does not work with every command, but always works with "close" ("Close all"). Also using "all" may limit optional parameters (see some conversations below).
- MCI file names should be "short" (8.3) by design ;=) However, using double quotes to enclose the file name (like "Long movie name.mpeg") seems to work with all MCI versions and platforms. Also fully-pathed file names seem to open faster.
- One or more parameters may be required, and depend upon the command being used.
- Using the "all" <device> name may void the use of any parameters, including notify & wait.
- Be aware that using wait with real devices or huge files like full-length movies may cause an intolerable delay (!) and will create a blocking situation: nothing happens until the device has finished the command. For example, "seek DAT to Start wait" may take a long time to process if currently end of tape. Of course, blocking or "waiting" may be preferable in situations where the next line of code depends upon the current MCI command either executing or failing.
