LEADTOOLS Getting Started with Multimedia

A module that combines audio and video into one file.

The driver that writes the data (burns the data) to the DVD. It is the software that burns the DVD image to the physical media.DVD image to the physical media.DVD image to the physical media.DVD image to the physical media.

A set of files that contain all of the video and audio content for a DVD, organized with a table of contents (optional). See also: Title , Chapter , ISO Image .

The name for a group of related video files (called "Chapters") on your DVD. For example, for a DVD called "My Summer Vacation," you might have the titles "Water Skiing," "New Friends," and "Hiking." For each of those titles, you might have one or more different video files.

The name for each individual video file on a DVD. For example, under the title "Water Skiing", you might have the chapters "My first try," "My first wreck," and "My first jump."

An ISO image (.iso) is a disk image of a file system. It includes data files that are contained in the ISO image along with filesystem metadata. ISO images are an alternative to physical media for distribution of a "DVD" over the Internet. Most operating systems allow ISO images images to be "played" as if they were physical discs. See also: DVD Image.

Multimedia Files You Must Include With Your Application (Redistributables)

Show in webframe

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 features are created:

 

Redist\MM\CDLL\Win32

Redist\MM\Dotnet\Win32

Redistributable Multimedia feature files for Win32 systems

Redist\MM\CDLL\x64

Redist\MM\Dotnet\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.

 

The 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, you do not need to install these components on computers that have Windows Media 9 player installed.

 

Note:

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

Note:

Multimedia 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 deployment license. See Multimedia Licensing.

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 Multimedia features (LTMM), you need to unlock one of the following toolkits or modules:

Note:

The Still Image filters (reader and writer) require a LEADTOOLS Imaging Pro license.

Note:

The LEADTOOLS MMS Sink filter depends on Windows Media components (including WMVCore.dll). When installing this filter on Windows Server 2008 systems, you may need to install the Windows Desktop Experience feature.

The following table summarizes the files you must include 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 recommended that you 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, please refer to the  

 Evaluation Mechanism Overview  and the LMDSKernel2 Object
