分两块：

1.取得摄像头采集的视频流

2.发送到服务器端

    protected MediaRecorder mMediaRecorder;
    private LocalServerSocket mLss = null;
    private LocalSocket mReceiver, mSender = null;
    mLss = new LocalServerSocket("myVideoStream");
    
    mReceiver = new LocalSocket();
    //连接mLss，即接受方主动发起连接
    mReceiver.connect( new LocalSocketAddress("myVideoStream")); 
    mReceiver.setReceiveBufferSize(100*1024);
    mSender = mLss.accept();
    mSender.setSendBufferSize(100*1024);
    mMediaRecorder.start();
    
    //mReceiver已经和mSender建立连接，也就可以认为，camera采集的视频流会持续
    //发给mReceiver，通过mReceiver.getInputStream()就可以获取到mSerder输入的视频流
    mSocketHelper.setInputStream(mReceiver.getInputStream());
    //mSocketHelper是你自己对Socket的封装，根据mMediaRecorder的不同的编码格式，实现不同的发送方式
    mSocketHelper.start();
