Documentation's Desktop Capture with Cancelation Token Example is not working.

[GeraldEugenio]

Hi,

I want to start and stop desktop screen recording programmatically and I tried this code from the documentation and put it in a Console App (.Net 5) but unfortunately, I haven't successfully executed the said code. The app is freezing and I have to manually stop the app and kill the ffmpeg.exe process in the Task Manager since it consumes large resources. Also, the output file was zero bytes.

using System.IO;
using System.Threading;
using System.Threading.Tasks;
using Xabe.FFmpeg;

namespace ScreenRecording
{
    internal class Program
    {
        static async Task Main(string[] args)
        {
            string output = Path.Combine("C:", "Temp", "desktop_capture.mp4");

            CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();

            await FFmpeg.Conversions.New()
                .AddDesktopStream()
                .SetOutput(output)
                .SetOverwriteOutput(true)
                .Start(cancellationTokenSource.Token);

            await Task.Delay(5000);
            cancellationTokenSource.Cancel();
        }
    }
}

Hello @GeraldEugenio

Awaiting conversion blocks your thread. You have to run it in separate task or use CancellationTokenSource with time limit
