MCI-Browser V1.44 - A simple player for audio and video files

  This page is available in German language too
MCI-Browser is a simple player for audio and video files without a lot of mouse clicks...

The MCI-Browser plays all formats that are supported by DirectShow or the Windows Media Control Interface (MCI).

Why two multimedia interfaces?
MCI is the old-fashinoned interface from the Windows 3.0 era. So MCI-Browser works under the very first version of Windows 95 as it does with Windows NT 4.0 without any Service Pack. And it's very simple to program it.
DirectShow is the uptodate interface that can properly handle multiple video and audio streams in a file. unfortunately I had started the development of MCI-Browser using Visual Basic where I can use a subset of DirectShow only.

If a file is opened for write by another application DirectShow refuses to play the file even shared read access is allowed. In this case MCI-Browser create a temporary copy and plays it.

You can integrate external applications thru the MCIbrowser.ini (items ShellPathX and ShellNameX). They appear in the popupmenu of the filelist under 'Open with...'. Since Version 1.20 it works thru the settings dialog too.
Useful Apps maybe DivFix, AviPreview, GraphEdit and MPlayerClassic.

Incomplete AVI files can be repared using DivFix. If you put the DivFix.exe into the MCI-Browser folder of if you enter its path into the MCIBrowser.ini, then MCI-Browser executes DivFix for this file when needed (for a temporary copy, not the original).

If a file doesn't play, you can install an additional DirectShow Filter:

  • MP3
    For MP3 files you can install Microsoft's Windows Media Player 6.4 witch includes several filters. But this should only be needed under Windows 95 and NT4.
  • OGG
    For Ogg Vorbis there is a DirectShow at
  • AC3 Audio
    For AC3 you find a filter at
  • DivX/Mpeg4
    For DivX and MPEG4 videos there are DivX, Xvid or ffdshow
  • MJPG
    Digital foto cameras with video function creates often AVI files with Motion JPEG. DirectX8 and higher shall include an MJPEG filter. Otherwise try ffdshow
  • MOV, QT (Apple QuickTime), MP4
    For QuickTime videos usually you need Apple's QuickTime. To play them with the Media-Player or MCIBrowser you need this:
    QuickTime Alternative
    But there are reports about messed up systems...
    Nero6 seems to include filters for QuickTime too.
  • RealAudio, RealMedia
    For RealAudio and RealMedia usually you need the RealPlayer. To play them with the Media-Player or MCIBrowser you need this:
    Real Alternative
    But as with "Qucktime Alternative" there are reports about messed up systems...
  • MPEG-2
    For MPEG-2 videos (e.g. SVCD, VOB) there is a SourceForge project too:
    GPL MPEG-1/2 DirectShow Decoder Filter.
    The latest version of ffdshow works too.
  • Microsoft Windows Media
    For WMA, WMV, ASF from Microsoft there is the Windows Media 9 Codec. If the 9er codecs doesn't help or if you are using Win95 or NT4, you can try the Windows Media 8 Codecs.
    For WMV3 you need wmv9VCMsetup.
  • 3GP and 3G2 mobile video
    These small mobile videos are MPGE-4 derivates. The latest version of ffdshow can handle them but maybe you need the Haali Matroska Splitter too.
  • Flash-Video (FLV)
    The latest version of ffdshow helps here too. A splitter is required too, like this one: FLVSplitter.

If WMV videos look 'blocky' if scaled then an update of the DX9 runtime helps (also under Win7):

If a video 'occationally' plays with lower quality or strange in any way, usually a nasty DirectShow Filter has obtruded on your system. To see which filters are used for a media file there is the Microsoft tool GraphEdit. After starting the program don't click open (this opens a filter graph). Click in the File menu 'Render Media File'. Once you have identified the nasty filter, you can unregister this filter or lower its priority (the merit). A tool for this purpose is the DirectShow FilterManager.

Apart from that a visit at MovieCodec, Free-Codecs or may be a good idea.

Back to the MCI-Browser:

A commandline can be used for going directly to a folder or to play a file.

You can select several files too (as known from the Windows Explorer) which are played successive then.

For playing all files you can either check the 'all' checkbox or you can select all files.

Using the GoTo button you can go to before assigned folders. Microsoft would call it 'Favourites'...

Using the CopyTo and MoveTo buttons you can move or copy files to before assigned folders. In later versions of MCI-Browser you will can press Alt+1 to 9 on the keyboard too to move or Shift+1 to Shift+9 to copy files.

The volume control "File" is locally only, the others are system wide:
"Wave" is for the Wave 'input' of the soundcard, "MIDI" for the FM synthesizer input and "Master" for the output to the boxes. BTW: The contol you get by click on the speaker icon in the taskbar is the master volume control. And the volume control of the Windows Media Player is a local one for the played file.
