Media Foundation Files You Must Include With Your Application (Redistributables)

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

Architecture Path Description
Win32 Bin\CDLL\Win32 Redistributable Media Foundation feature files for Win32 systems.
Bin\DotNet4\Win32
x64 Bin\CDLL\x64 Redistributable Media Foundation feature files for x64 systems.
Bin\DotNet4\x64

The LEADTOOLS Media Foundation toolkit requires Microsoft Media Foundation core DLLs for full multimedia functionality. In particular, the MF.DLL and MFPLAT.DLL files, which are the Media Foundation kernel modules, must be installed on the computer.

The Media Foundation APIs are part of the Windows SDK. To develop a Media Foundation application, install the latest version of the Windows SDK.

✎ NOTE

LEADTOOLS Media Foundation redistributable files are all COM-based, unless otherwise specified, and must be registered by your installation procedure.

✎ NOTE

Certain standards-based technology may require patent licenses from third party patent holders. The license provided by LEAD does not include any third party patent licenses, and it is your responsibility to acquire any third party licenses that are required. In certain cases where LEAD is aware of the existence of third party patents covering a standard, LEAD has acquired a patent license that covers the LEADTOOLS SDK, but we do not have the right to sublicense the patents. Where LEAD has acquired a patent license for a specific technology, the contact information for the patent holder/agent is supplied in the following table. LEAD makes no representations or warranties whatsoever to the effect that the patent holders mentioned constitute all persons holding patents covering the standards-based technology that is included in the Software.

\* LEAD Media Foundation components 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 Media Foundation modules. \*\* 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 that are placed in the %windir%\System32 folder since that is a 32-bit application.

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