Important Update
The code below will help you to implement an C++ (managed) app to capture video from entire screen as WEBM. 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 be used to capture video from entire screen as WEBM using C++ (managed).
C++ (managed) code samples for C++ (managed) developers help to speed up coding of your application when using ByteScout Screen Capturing SDK. In your C++ (managed) project or application you may simply copy & paste the code and then run your app! Code testing will allow the function to be tested and work properly with your data.
Our website provides trial version of ByteScout Screen Capturing SDK for free. It also includes documentation and source code samples.
