Create a screen recorder using C#

Introduction

In this tip, we create a customized screen recorder using C#.NET.

Background

At work, we wanted a screen recorder to record the procedure. Unfortunately, we don't have any screen recorder. So I developed a screen recorder in C# to record our screen.

Using the Code

At first, create a source and install Accord.Video.FFMPEG from nuget library.

Image 1

Screen recorder is created by a timer and VideoFileWriter.

First of all, initialize a timer control and assign properties to the control. Then, create a tick event to that timer .

timer1 = new Timer();
timer1.Interval = 20;
timer1.Tick += timer1_Tick;
vf = new VideoFileWriter();
vf.Open("Exported_Video.avi", 800, 600, 25, VideoCodec.MPEG4, 1000000);

Create a start button to start the timer.

private void button1_Click(object sender, EventArgs e)
{
    timer1.Start();
}

In the timer tick event, create a bitmap image from the size of VideoFileWriter and capture screen and write it to bitmap image. Then, write the image to VideoFileWriter.

private void timer1_Tick(object sender, EventArgs e)
{
    bp = new Bitmap(800, 600);
    gr = Graphics.FromImage(bp);
    gr.CopyFromScreen(0, 0, 0, 0, new Size(bp.Width, bp.Height));
    pictureBox1.Image = bp;
    pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
    vf.WriteVideoFrame(bp);
}

Create a stop button to stop the timer and save the file.

private void button2_Click(object sender, EventArgs e)
{
    timer1.Stop();
    vf.Close();
}
