How to capture video from entire screen in C++ (unmanaged) and ByteScout Screen Capturing SDK

Write code in C++ (unmanaged) to capture video from entire screen with this step-by-step tutorial

Learn how to capture video from entire screen in C++ (unmanaged) with this source code sample. What is ByteScout Screen Capturing SDK? It is the screen video recording SDK helps in quick implementation of screen video recording. WMV, AVI, WebM output options are available with adjustable quality, video size, framerate and video and audio codec. Includes special features like live multiple blacking out of selected areas, recording from web cam as main source and as overlay, optional watermarks for output video. It can help you to capture video from entire screen in your C++ (unmanaged) application.

This rich sample source code in C++ (unmanaged) for ByteScout Screen Capturing SDK includes the number of functions and options you should do calling the API to capture video from entire screen. Just copy and paste the code into your C++ (unmanaged) application’s code and follow the instruction. Enjoy writing a code with ready-to-use sample codes in C++ (unmanaged).

Trial version of ByteScout Screen Capturing SDK can be downloaded for free from our website. It also includes source code samples for C++ (unmanaged) and other programming languages.
