Here is a snap example of using the CSFFmpeg using C#:

CSFFmpeg-Snap-Example.cs

//Create a new instance of the library with the direction of the ffmpeg libraries

_CSFFmpeg = new CSFFmpeg.CSFFmpeg(@"../../../libs/ffmpeg/x86/bin", "UserName", "RegKey");

//Set the arguments
_CSFFmpeg.ArgsDirect = txtArguments.Text;

//Events

//On ffmpeg output event
_CSFFmpeg.OperationOutput += (o, s) =>
{
    //Display in the results in the text box
};

//On start event
_CSFFmpeg.OperationStart += (o) =>
{
    lblStatus.Text = "Start";

};

//On progress event
_CSFFmpeg.OperationProgress += (o, s) =>
{
    progressBar1.Value = s;
};

//Done
_CSFFmpeg.OperationDone += (o) =>
{
    this.Invoke(new Action(() =>
    {
        lblStatus.Text = "Done";
    }));
};

//Run the ffmpeg from the program
_CSFFmpeg.Run();
