我想同时录制视频和音频但不知道如何做？

Question

我正在使用accord.net，我分别录制音频和视频，但我想同时进行这两项操作，因为我会在使用套接字将其录制在另一个应用程序中时读取带有声音的视频。

我在某处读到使用视频文件写入器，但我不知道如何将它与音频一起使用。 我在后台运行录音，因为它会使表单冻结。

  public Form1()
    {
        InitializeComponent();
 // back ground running
        bg = new BackgroundWorker();
        bg.WorkerSupportsCancellation = true;
        bg.DoWork += Run;
        audiostream = new MemoryStream();
        audioencoder = new WaveEncoder(audiostream);            
    }    
 private void Form1_Load(object sender, EventArgs e)
    {
        VideoCaptureDevices = new 
        FilterInfoCollection(FilterCategory.VideoInputDevice);
        captureDevice = new VideoCaptureDeviceForm();
    }

 private void source_NewFrame(object sender, Accord.Audio.NewFrameEventArgs eventArgs)
    {
        audioencoder.Encode(eventArgs.Signal);
    }

    void FinalVideo_NewFrame(object sender, Accord.Video.NewFrameEventArgs eventArgs)
    {
        video = (Bitmap)eventArgs.Frame.Clone();
        pictureBox1.Image = (Bitmap)eventArgs.Frame.Clone(); ;
    }

 private void record_Click(object sender, EventArgs e)
 {
        source = new AudioCaptureDevice()
        {
            // Listen on 44.1 Hz, Cam Quality 1280x720
            DesiredFrameSize = 4096,
            SampleRate = 44100,
        };

 saveFileDialog2.Filter = "Wav Files (*.wav)|*.wav";
 saveFileDialog2.InitialDirectory = @"C:\Users\dell\Desktop\Camrecord";
 saveFileDialog1.Filter = "Avi Files (*.avi)|*.avi";
 saveFileDialog1.InitialDirectory = @"C:\Users\dell\Desktop\Camrecord";

 int h = captureDevice.VideoDevice.VideoResolution.FrameSize.Height;
 int w = captureDevice.VideoDevice.VideoResolution.FrameSize.Width;
 audiofilestream = new FileStream(saveFileDialog2.FileName, 
FileMode.Create);
 FileWriter.Open(saveFileDialog1.FileName, w, h, 155, VideoCodec.MPEG4, 
3200000);
source.NewFrame += source_NewFrame;
source.Start();
bg.RunWorkerAsync();

}

 private void Run(object sender, DoWorkEventArgs e)
    {
        audioencoder = new WaveEncoder(audiofilestream);

        do
        {
            Runexecuted = true;               
            FileWriter.WriteVideoFrame(video);

       } while (!Stopclicked);

        FinalVideo = captureDevice.VideoDevice;
        FinalVideo.NewFrame += new 
        NewFrameEventHandler(FinalVideo_NewFrame);
        source.NewFrame += source_NewFrame;
        source.Start();
        FinalVideo.Start();
    }

如果您知道如何合并它们，我可以使用它，等待适合我的解决方案。谢谢大家。

您必须在录制结束时设置保存事件，而不是在开始时。
