A sample code that achieves the requirement

I am building an application in WPF using.NetFramework. It can record full or partial desktop along with Audio to an mp4 file. Right now I am using ffmpeg for that which works fine but has certain issues.

I want to give a try to Desktop Duplication API. Most of the related repositories I find on github are several years old. Why there's very little latest information available on this topic, especially for C#? Can you share any starting points that meet my requirements?

Answer 1

As one of the comments mention Desktop Duplication API is a native low-level API, check this repo https://github.com/bmharper/WindowsDesktopDuplicationSample .

I read also your comment regarding "stick to WPF", there are 2 options in my opinion.

The first one is a very simple RecordBook-Screen-Recorder, it is made in WinForms, and the UI is not in English but very easy to understand, I share it for inspiration: https://github.com/iEmreM/RecordBook-Screen-Recorder .

That said, I have previously played with Captura open source recording in .net and WPF, it can capture video and sound.

here is the repo, the latest updated 2 years. https://github.com/MathewSachin/Captura .

It is feature-rich software as well.

With that said, you might search and find something more, but you won't find complete software that has everything without issues.

In addition, check this article does not cover what you need but gives inspiration to your comment regards Windows Graphic Capture API. https://blogs.windows.com/windowsdeveloper/2019/09/16/new-ways-to-do-screen-capture/
