SWF to WMV with live preview in C# using ByteScout SWF To Video SDK

Write code in C# to make SWF to WMV with live preview with this How-To tutorial

Today we will explain the steps and algorithm of implementing SWF to WMV with live preview and how to make it work in your application. ByteScout SWF To Video SDK was made to help with SWF to WMV with live preview in C#. ByteScout SWF To Video SDK is the SDK that is capable of converting SWF macromedia files into WMV and AVI video. Supports dynamic flash movies, can transmit variable values. Options to change output video size, framerate, quality are available.

This rich sample source code in C# for ByteScout SWF To Video SDK includes the number of functions and options you should do calling the API to implement SWF to WMV with live preview. In order to implement this functionality, you should copy and paste code below into your app using code editor. Then compile and run your application. C# application implementation typically includes multiple stages of the software development so even if the functionality works please test it with your data and the production environment.

Trial version can be downloaded from our website. Source code samples for C# and documentation are included.
