Frame Rate Controller Filter and our Video resize Filter Example

LEADTOOLS provides many audio and video processing filters, which allow you to create an audio/video file with your custom settings. The settings of these filters can be controlled via the properties dialog that we provide, or programmatically through your application. Attached is a basic application written in VB.NET, which demonstrates how to access and control our filters programmatically. This particular example makes use of our Frame Rate Controller Filter and our Video resize Filter, but all of our filters can be accessed and controlled in the same fashion.

This example allows you to choose a source and destination directory. It will browse for every AVI it finds in the source directory, apply the filters, and convert the files. It will allow you to specify a custom frame rate/video size, or you can use the frame rate/video size from an existing video file. There is also a "Get File Information" button, which allows you to view all relevant information about a specific file.

If you have any questions about this example, please post them to this thread. Thanks,

This sample is written in C# using Visual Studio 2008 and LEADTOOLS Multimedia COM version 17.

The demos main purpose is to show you how to add a multimedia filter to the stream and how to make changes to it's settings, all in code.

The demo also enumerates the devices on your machine and allows you to select one with the resize filter still present in the stream.
