Answering author's question:

Does ffmpeg requires to be installed server side or just exe is enough?

ffmpeg.exe will be enough, no installation is required.

The code below gets a screenshot on captureTime on video specified by videoFilename variable, and saves it to the imageFilename path.

Process ffmpeg = new Process();
ffmpeg.EnableRaisingEvents = true;
ffmpeg.StartInfo = new ProcessStartInfo
{
    FileName = this.ffmpegPath,
    Arguments = string.Format(
        "-i \"{0}\" -an -y -s 320x240 -ss {1} -vframes 1 -f image2 \"{2}\"",
        this.videoFilename,
        DateTime.MinValue.Add(this.captureTime).ToString("HH:mm:ss:ff", CultureInfo.InvariantCulture),
        this.imageFilename
    ),
    WorkingDirectory = this.workingDirectory,
    UseShellExecute = false,
    RedirectStandardError = true,
    RedirectStandardOutput = true,
    WindowStyle = ProcessWindowStyle.Hidden
};

ffmpeg.Start();
ffmpeg.WaitForExit(this.timeout);
