Multimedia Files You Must Include With Your DirectShow-based Application (Redistributables)

Installation Directory

The installation procedure creates a directory tree for the LEADTOOLS files, and adds the demonstration programs and online help to the desktop. You specify the root directory during installation. The following subdirectories for Multimedia features are created:

Subdirectory Description
Redist\MM\CDLL\Win32
Redist\MM\Dotnet4\Win32
Redistributable Multimedia feature files for Win32 systems
Redist\MM\CDLL\x64
Redist\MM\Dotnet4\x64
Redistributable Multimedia feature files for x64 systems
Redist\MM\CDLL\Win32\RequiresLicensing Redistributable Multimedia feature files for Win32 systems that require special licensing
Redist\MM\CDLL\x64\RequiresLicensing Redistributable Multimedia feature files for x64 systems that require special licensing

Microsoft Redistributables

LEADTOOLS Multimedia features require Microsoft DirectShow 8.0 or later for full multimedia functionality. In particular, the QUARTZ.DLL file, which is the DirectShow kernel module, must be installed on the computer.

To save Windows Media (WMV) with full functionality (create video-only files, use custom, non-Microsoft codecs in WMV files, etc.), the latest Windows Media Components are required. These components are included in an installation package named WMFDist95.exe, present in the Redist\MM folder. These components are also included in Windows Media Player 9 and later versions. Therefore, it is not necessary to install these components on computers that have Windows Media 9 player installed.

Special Notices

Redistributables for WIN32\x64 Systems

There are two sets of folders for the redistributables, as follows:

The following table summarizes the files that must be included on your distribution media to support the LEADTOOLS Multimedia features functions on a WIN32\x64 system.

* LEAD DirectShow components now rely on an external object to determine the operation mode: Release or Evaluation. This external object, called DSKernel, should be used to unlock/lock LEAD DirectShow modules.

** Requires additional LEADTOOLS SDK depending on which raster formats are required.

*** It is best to install the x64 runtime in the %windir%\SYSWOW64 folder instead of the %windir%\System32 folder because some development environments (like VS8) will not import references placed in the %windir%\System32 folder since that is a 32-bit application.

For more information on the evaluation mechanism and the DSKernel object, please refer to the Evaluation Mechanism Overview and the LMDSKernel2 Object
