How to capture video from given window in C# and ByteScout Screen Capturing SDK

This code in C# shows how to capture video from given window with this how to tutorial

Every ByteScout tool contains example C# source codes that you can find here or in the folder with installed ByteScout product. ByteScout Screen Capturing SDK is the SDK for developers for quick implementation of screen video recording. The SDK records screen into video or into a series of screenshots. Can also record audio. Saves video into AVI,WMV and Google’s WebM. Output video quality, size, resolution or framerate can be adjusted easily. Provides additional tools for privacy features like blacking out on scren areas with sensitive information on screen right during recording. Supports web camera as input and can add instant text and images into video output and you can use it to capture video from given window with C#.

The SDK samples like this one below explain how to quickly make your application do capture video from given window in C# with the help of ByteScout Screen Capturing SDK. Just copy and paste the code into your C# application’s code and follow the instruction. Enjoy writing a code with ready-to-use sample C# codes.

// NOTE: if you are getting error like "invalid image" related to loading the SDK's dll then 
// try to do the following:
// 1) remove the reference to the SDK by View - Solution Explorer
// then click on References, select Bytescout... reference name and right-click it and select Remove
// 2) To re-add click on the menu: Project - Add Reference
// 3) In "Add Reference" dialog switch to "COM" tab and find Bytescout...
// 4) Select it and click "Add" 
// 5) Recompile the application 
// Note: if you need to run on both x64 and x86 then please make sure you have set "Embed Interop Types" to True for this reference
