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 Streaming features are created:
Redist\MS\CDLL\Win32 Redist\MS\Dotnet\Win32 Redist\MS\Dotnet4\Win32 |
Redistributable Media Streaming feature files for Win32 systems |
Redist\MS\CDLL\x64 Redist\MS\Dotnet\x64 Redist\MS\Dotnet4\x64 |
Redistributable Media Streaming feature files for x64 systems |
| Redist\MM\CDLL\Win32 | Redistributables common to Media Streaming and Multimedia toolkits for Win32 systems |
| Redist\MM\CDLL\x64 | Redistributables common to Media Streaming and Multimedia tookits for x64 systems |
Note: |
LEADTOOLS Media Streaming redistributable files are all COM-based, unless otherwise specified, and must be registered by your installation procedure. |
Note: |
Some Media Streaming 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 Streaming 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 |
Note: |
You may not distribute the header files with your application, and you may not provide software development capabilities in your application. |
Note: |
To unlock the LEADTOOLS Streaming features (LTMS), you need to unlock the following module: The Media Streaming module will automatically use DSKernel2.dll to unlock any other required Multimedia redistributable (for example, LMISODmx.dll, LMFLVDmx.dll). So you just need to redistribute DSKernel2.dll, LMISODmx.dll, LMFLVDmx.dll and set the runtime license properly as described in Setting the Runtime license. |
Note: |
The Windows 10 Anniversary Update includes changes to Microsoft Edge that affect how Flash content is displayed. If you are enabling Flash with the LEADTOOLS Media Server and testing on Microsoft Edge, refer to Windows 10 Update Effects On Edge. |
The following table summarizes the files you must include on your distribution media to support the LEADTOOLS Media Streaming features functions on a WIN32 system.
The (Redist\MS\CDLL) & (Redist\MS\Dotnet\) folders contain the files you are licensed to use with the LEADTOOLS Media Streaming SDK
The Redist\MM\CDLL folders contain the files common to LEADTOOLS Multimedia and LEADTOOLS Media Streaming SDK. Currently, all the files listed in the table below with the exception of LTMS are contained in Redist\MM\CDLL.

*** 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.
