How to capture video from region around mouse in C# using ByteScout Screen Capturing SDK

How to code in C# to capture video from region around mouse with this step-by-step tutorial

The code below will help you to implement an C# app to capture video from region around mouse. ByteScout Screen Capturing SDK is the tool for developers who want to add screen capturing in their application. Can record screen into video and into single screenshots. Output formats are WMV, AVI, WebM for video and PNG for screenshots. You can adjust output video size, quality, resolution, framerate, video and audio codecs. Includes special privacy features for blacking out sensitive information on screen. Can also capture video from web camera, can add overlays with text or images and you can use it to capture video from region around mouse with C#.

The SDK samples like this one below explain how to quickly make your application do capture video from region around mouse in C# with the help of ByteScout Screen Capturing SDK. This C# sample code is all you need for your app. Just copy and paste the code, add references (if needs to) and you are all set! Enjoy writing a code with ready-to-use sample codes in C#.

using BytescoutScreenCapturingLib; // import bytescout screen capturing activex object 

// 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
