{
timerVideo.Start();

VideoCaptureDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
captureDevice = new VideoCaptureDeviceForm();
}

private void butStart_Click(object sender, EventArgs e)
{
if (captureDevice.ShowDialog(this) == DialogResult.OK)
{
VideoCaptureDevice videoSource = captureDevice.VideoDevice;
FinalVideo = captureDevice.VideoDevice;
FinalVideo.NewFrame += new NewFrameEventHandler(FinalVideo_NewFrame);
FinalVideo.Start();
}
}

private void FinalVideo_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
video = (Bitmap)eventArgs.Frame.Clone();
pbVideo.Image = (Bitmap)eventArgs.Frame.Clone();
//writer = new VideoFileWriter();
writer.WriteVideoFrame(video);
}

private void butRecord_Click(object sender, EventArgs e)
{
try
{
path = Path.GetDirectoryName(Application.ExecutablePath) + @"\Videos\";
if (Directory.Exists(path) == false)
{
Directory.CreateDirectory(path);
}

int h = captureDevice.VideoDevice.VideoResolution.FrameSize.Height;
int w = captureDevice.VideoDevice.VideoResolution.FrameSize.Width;

writer.Open(path + "VID" + DateTime.Now.ToString("hhmmss") + ".mp4", w, h, 25, VideoCodec.MPEG4);

//writer.Close();

}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

private void butStop_Click(object sender, EventArgs e)
{
if (FinalVideo == null)
{ return; }
if (FinalVideo.IsRunning)
{
writer.Close();
pbVideo.Image = null;
}
else
{
this.FinalVideo.Stop();
writer.Close();
pbVideo.Image = null;
}
}

AccessViolationException was Unhanded : "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

no, not at same time
the user can save his preferred one and i need it with less memory taking.
