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 | Redist\MF\CDLL\Win32 | Redistributable Media Foundation feature files for Win32 systems. |
| Redist\MF\Dotnet4\Win32 | ||
| x64 | Redist\MF\CDLL\x64 | Redistributable Media Foundation feature files for x64 systems. |
| Redist\MF\Dotnet4\x64 | ||
| Win32/x64 Special Licensing | Redist\MF\CDLL\Win32\RequiresLicensing | Redistributable Media Foundation feature files for Win32 systems that require special licensing. |
| Redist\MF\CDLL\x64\RequiresLicensing | Redistributable Media Foundation feature files for x64 systems that require special licensing. |
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.
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\MF folder. These components are also included in Windows Media Player 9 and later versions. Therefore, you do not need to install these components on computers that have Windows Media 9 player installed.
✎ NOTE
LEADTOOLS Media Foundation redistributable files are all COM-based, unless otherwise specified, and must be registered by your installation procedure.
✎ NOTE
Some Media Foundation features are provided for evaluation purposes only. You may not copy, redistribute or deploy in production any of the following files without obtaining the proper license. In some cases, the license is included with your initial purchase of LEADTOOLS Media Foundation SDK. In other cases, you must obtain a license from LEAD by entering into a Duplication and Distribution License. See Licensing. For these special licensing situations, see the notes below accompanying the specific file.
✎ 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 encourages its customers to conduct their own due diligence regarding the potential for third party patents on any features that are being incorporated into the application.
