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

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

ByteScout tutorials are designed to explain the code for both C# beginners and advanced programmers. 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. It can capture video from given region in C#.

You will save a lot of time on writing and testing code as you may just take the C# code from ByteScout Screen Capturing SDK for capture video from given region below and use it in your application. Follow the instructions from the scratch to work and copy the C# code. Implementing C# application typically includes multiple stages of the software development so even if the functionality works please test it with your data and the production environment.

// 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
