如何将从麦克风录制的音频数据发布到摄像机 [英] How Do I Post Audio Data Which Is Being Recorded From Microphone To Camera

问题描述

i am trying to send audio to a AXIS M1054 Network Camera. When i start my application, it after sending 6 packets to the camera shows an error:"An established connection was aborted by the software in your host machine"

here's the code

namespace sound_stream
        {
            public partial class Form1 : Form
            {
                public static IWaveIn waveSource = null;
                public Socket cameraAudioSocket = null;
                public IPEndPoint remoteEndPoint = null;
                public string camera_address = "192.168.1.22";
                public int camera_port = 81;

                }

                private void start_Click(object sender, EventArgs e)

                        waveSource = new WaveIn();
                        waveSource.WaveFormat = new WaveFormat(8000, 1);
                        CameraSetup();

我在stackoverflow上发布了这个问题这是链接，有人向我们建议HttpClient或Webclient，所以我可以使用它们发送音频，如果是，那么如何？

请帮忙。

I posted the question on stackoverflow Here's the Link and someone suggested to us HttpClient or Webclient so can i use them to send audio and if yes then how??
please help.
