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 .

C#
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.

C#
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.

C#
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.

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

I really hate it when people give low score for silly reasons. If you have written something that avoids the library, you should post your own article. If you have ever posted an article, you would understand how much work it is to do and, with your example, how much you leave yourself exposed to unremarkable comments.

Unless the code or theory is significantly flawed, don't vote one. The only thing he failed in was his ability to impress you.

Arun, good article and try to keep up the good work.
