Recording using AForge's VideoFileWriter


I am having trouble recording a video from my webcam. I tried implementing the VideoFileWriter but keep getting the error "The specified module could not be found. (Exception from HRESULT: 0x8007007E)". Whenever i comment out the video writer everything works great but when attempting to record it to the hards drive using the writer the I get the error. I hope that this is a easy problem to solve. Below is the code i have.

private FilterInfoCollection VideoCaptureDevices;
        private VideoCaptureDevice FinalVideoSource;
        Bitmap image;
        private VideoFileWriter writer;

        void VideoShow()
            VideoCaptureDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            FinalVideoSource = new VideoCaptureDevice(VideoCaptureDevices[0].MonikerString);
            FinalVideoSource.NewFrame += new NewFrameEventHandler(FinalVideoSource_NewFrame);
            FinalVideoSource.DesiredFrameRate = 15;
            FinalVideoSource.DesiredFrameSize = new Size(1280, 800);

        void FinalVideoSource_NewFrame(object sender, NewFrameEventArgs eventArgs)
            image = (Bitmap)eventArgs.Frame.Clone();
            pictureBox1.Image = image;

        public AForgeRecorder()

        private void btnStart_Click(object sender, EventArgs e)
            writer = new VideoFileWriter();
            writer.Open(@"C:\testvvid.avi", 1280, 800, 15, VideoCodec.MPEG2, 128);

        private void btnStop_Click(object sender, EventArgs e)
            if (writer != null)

Thanks in advance

it's easy, Afrog VideoFileWriter used FFMPEG.dll, so download FFMPEG zip, copy all 5 dll from bin(avcodec-53.dll,.....etc), to your project, right clik on your project , click add existing reference, select all dll, make their propery as always copy, + you need .net 3.5 or less. so use lower frame work
