Rtp 协议实现网络广播台网络收音机

RTP协议介绍:http://www.360doc.com/content/11/1009/15/496343_154624612.shtml

本文中使用了 StreamCoders 的 RTP.net组件,此组件中有些和c++ 混合编程部分,我已将此组件转成全部c#代码

        RTPSession session;

        RTPReceiver receiver;

        RTPParticipant participant;



        WinSound.Player m_Player;

        public Form1()

        {

            InitializeComponent();

            m_Player = new WinSound.Player();

            List<String> names = WinSound.WinSound.GetPlaybackNames();

            m_Player.Open(names[0], 44100, 16, 2, 8);

        }



        private void btnListen_Click(object sender, EventArgs e)

        {

            IPAddress ipaddr;

            ushort usPort;



            if (!(IPAddress.TryParse(txtIp.Text, out ipaddr) && ushort.TryParse(txtPort.Text, out usPort)))

            {

                MessageBox.Show("IP地址或端口填写错误！");

                return;

            }

            session = new RTPSession();

            receiver = new RTPReceiver();

            IPEndPoint rtpEp = new IPEndPoint(ipaddr, usPort);



            participant = new RTPParticipant(rtpEp);

            session.NewRTPPacket = NewRTPPacket;

            session.NewRTCPPacket = NewRTCPPacket;

            receiver.AddParticipant(participant);

            session.AddReceiver(receiver);

        }



        bool NewRTPPacket(RTPPacket packet)

        {

            if (packet.DataPointer != null)

            {

                //Nach Linear umwandeln

                Byte[] linearBytes = WinSound.Utils.MuLawToLinear(packet.DataPointer, 16, 2);

                //Abspielen

                m_Player.PlayData(linearBytes, false);

            }

            return true;



        }
