blackout sensitive info on screen video in C# with ByteScout Screen Capturing SDK

How To: tutorial on blackout sensitive info on screen video in C#

Today we will explain the steps and algorithm of implementing blackout sensitive info on screen video and how to make it work in your application. ByteScout Screen Capturing SDK helps with blackout sensitive info on screen video in C#. 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.

This rich sample source code in C# for ByteScout Screen Capturing SDK includes the number of functions and options you should do calling the API to implement blackout sensitive info on screen video. This C# sample code should be copied and pasted into your application’s code editor. Then just compile and run it to see how it works. Use of ByteScout Screen Capturing SDK in C# is also explained in the documentation included along with the product.

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

// 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
