Important Update
These source code samples are listed and grouped by their programming language and functions they use. 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. It can be used to use video quality profiles using C#.
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 use video quality profiles. Just copy and paste the code into your C# application’s code and follow the instruction. 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.
Free trial version of ByteScout Screen Capturing SDK is available for download from our website. Get it to try other source code samples for C#.
