ScreenRecorderLib 6.5.0

ScreenRecorderLib

A .NET library for screen recording in Windows, using native Microsoft Media Foundation for realtime encoding to h264 video or PNG images. This library requires Windows 8 or higher to function, as well as Visual C++ Redistributable x64 or x86 installed, depending on platform compiled for. This library also requires Media Foundation to work, which have to be installed from Server Manager if run on Windows Server, or from the respective "Media Feature Pack" if run on a Windows N or KN version.

Available on NuGet.

Basic usage:

This will start a video recording to a file, using the default settings:

        using ScreenRecorderLib;
        
        Recorder _rec;
        void CreateRecording()
        {
            string videoPath = Path.Combine(Path.GetTempPath(), "test.mp4");
            _rec = Recorder.CreateRecorder();
            _rec.OnRecordingComplete += Rec_OnRecordingComplete;
            _rec.OnRecordingFailed += Rec_OnRecordingFailed;
            _rec.OnStatusChanged += Rec_OnStatusChanged;
	    //Record to a file
	    string videoPath = Path.Combine(Path.GetTempPath(), "test.mp4");
            _rec.Record(videoPath);
        }
        void EndRecording()
        {
            _rec.Stop(); 
        }
        private void Rec_OnRecordingComplete(object sender, RecordingCompleteEventArgs e)
        {
	    //Get the file path if recorded to a file
            string path = e.FilePath;	
        }
        private void Rec_OnRecordingFailed(object sender, RecordingFailedEventArgs e)
        {
            string error = e.Error;
        }
        private void Rec_OnStatusChanged(object sender, RecordingStatusEventArgs e)
        {
            RecorderStatus status = e.Status;
        }
