Tutorial on how to capture from entire screen as WEBM video in C++ (unmanaged)

With this source code sample you may quickly learn how to capture from entire screen as WEBM video in C++ (unmanaged). What is ByteScout Screen Capturing SDK? It 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. It can help you to capture from entire screen as WEBM video in your C++ (unmanaged) application.
