DirectShow Example Programs and Demos for Win32/x64

Show in webframe

The source code for the following demo programs are installed in separate EXAMPLES subdirectories of the path where you installed your product (<LEADTOOLS_INSTALLDIR>\Examples). You specify the root directory during installation.

The executables are installed in Bin subdirectories (such as C:\LEADTOOLS 18\Bin\CDLL\Win32). The executables that are shipped have "_Original" appended to the name. The ones you build do not have that added, so that you can distinguish between the two.

Note:

You can run the example programs on your system by clicking the appropriate buttons in the local help. If you try to run an example program that is not on your system, an error message will appear.
