How to record a screen or desktop using this tool?

Also interested in this.

Wanted to clarify if this question was left unanswered because the feature is not currently available (on Windows, it is done using ffmpeg -f gdigrab -i desktop), or because nobody bothered to answer?

@GeraldEugenio have you found any FFmpeg C# wrapper that supports screen recording?

does this answer your question?

Yep, but it turns out ffmpeg is very inefficient because gdigrab is an old gen tech. These days the desktop is in DWM DXGI buffers, and there's an efficient API in modern Windows SDK with less options but actually much more practical: https://github.com/MicrosoftDocs/SimpleRecorder/
