组播也就是通过MulticastSocket来进行开发，与DatagramSocket比较相类似，这次依然是用两个线程进行实现，发送线程MultiSendThread和接收线程MultiReceiveThread。废话不多说，开始码：
（一）MultiSendThread：
（1）初始化MuticastSocket
// 侦听的端口
try {
multicastSocket = new MulticastSocket(8082);
// 使用D类地址，该地址为发起组播的那个ip段，即侦听10001的套接字
address = InetAddress.getByName("239.0.0.1");
} catch (IOException e) {
e.printStackTrace();
}
(2)初始化AudioRecord
protected LinkedList<byte[] mRecordQueue;
int minBufferSize;
private static AcousticEchoCanceler aec;
private static AutomaticGainControl agc;
private static NoiseSuppressor nc;
AudioRecord audioRec;
byte[] buffer;
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
private void initAudio() {
//播放的采样频率 和录制的采样频率一样
int sampleRate = 44100;
//和录制的一样的
int audioFormat = AudioFormat.ENCODING_PCM_16BIT;
//录音用输入单声道 播放用输出单声道
int channelConfig = AudioFormat.CHANNEL_IN_MONO;
minBufferSize = AudioRecord.getMinBufferSize(
sampleRate,
channelConfig, AudioFormat.ENCODING_PCM_16BIT);
System.out.println("****RecordMinBufferSize = " + minBufferSize);
audioRec = new AudioRecord(
MediaRecorder.AudioSource.MIC,
sampleRate,
channelConfig,
audioFormat,
minBufferSize);
buffer = new byte[minBufferSize];
if (audioRec == null) {
return;
}
//声学回声消除器 AcousticEchoCanceler 消除了从远程捕捉到音频信号上的信号的作用
if (AcousticEchoCanceler.isAvailable()) {
aec = AcousticEchoCanceler.create(audioRec.getAudioSessionId());
if (aec != null) {
aec.setEnabled(true);
}
}
//自动增益控制 AutomaticGainControl 自动恢复正常捕获的信号输出
if (AutomaticGainControl.isAvailable()) {
agc = AutomaticGainControl.create(audioRec.getAudioSessionId());
if (agc != null) {
agc.setEnabled(true);
}
}
//噪声抑制器 NoiseSuppressor 可以消除被捕获信号的背景噪音
if (NoiseSuppressor.isAvailable()) {
nc = NoiseSuppressor.create(audioRec.getAudioSessionId());
if (nc != null) {
nc.setEnabled(true);
}
}
mRecordQueue = new LinkedList<byte[]();
}
(3)开始录制，并实时发送出去
@Override
public void run() {
if (multicastSocket == null)
return;
try {
audioRec.startRecording();
while (true) {
try {
byte[] bytes_pkg = buffer.clone();
if (mRecordQueue.size() = 2) {
int length = audioRec.read(buffer, 0, minBufferSize);
// 组报
DatagramPacket datagramPacket = new DatagramPacket(buffer, length);
// 向组播ID，即接收group /239.0.0.1 端口 10001
datagramPacket.setAddress(address);
// 发送的端口号
datagramPacket.setPort(10001);
System.out.println("AudioRTwritePacket = " + datagramPacket.getData().toString());
multicastSocket.send(datagramPacket);
}
mRecordQueue.add(bytes_pkg);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
（二）MultiReceiveThread
（1）初始化MulticastSocket
// 接收数据时需要指定监听的端口号
try {
multicastSocket = new MulticastSocket(10001);
// 创建组播ID地址
InetAddress address = InetAddress.getByName("239.0.0.1");
// 加入地址
multicastSocket.joinGroup(address);
} catch (IOException e) {
e.printStackTrace();
}
(2)初始化AudioTrack
byte[] buffer;
AudioTrack audioTrk;
private void initAudioTracker() {
//扬声器播放
int streamType = AudioManager.STREAM_MUSIC;
//播放的采样频率 和录制的采样频率一样
int sampleRate = 44100;
//和录制的一样的
int audioFormat = AudioFormat.ENCODING_PCM_16BIT;
//流模式
int mode = AudioTrack.MODE_STREAM;
//录音用输入单声道 播放用输出单声道
int channelConfig = AudioFormat.CHANNEL_OUT_MONO;
int recBufSize = AudioTrack.getMinBufferSize(
sampleRate,
channelConfig,
audioFormat);
System.out.println("****playRecBufSize = " + recBufSize);
audioTrk = new AudioTrack(
streamType,
sampleRate,
channelConfig,
audioFormat,
recBufSize,
mode);
audioTrk.setStereoVolume(AudioTrack.getMaxVolume(),
AudioTrack.getMaxVolume());
buffer = new byte[recBufSize];
}
(3)开始接收，并进行实时播放
@Override
public void run() {
if (multicastSocket == null)
return;
//从文件流读数据
audioTrk.play();
// 包长
while (true) {
try {
// 数据报
DatagramPacket datagramPacket = new DatagramPacket(buffer, buffer.length);
// 接收数据，同样会进入阻塞状态
multicastSocket.receive(datagramPacket);
audioTrk.write(datagramPacket.getData(), 0, datagramPacket.getLength());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
（三）开始测试
MultiSendThread multiSendThread;
MultiReceiverThread multiReceiverThread;
@OnClick({R.id.btnSend, R.id.btnReceive})
public void onViewClicked(View view) {
switch (view.getId()) {
case R.id.btnSend:
if (multiSendThread == null) {
multiSendThread = new MultiSendThread();
}
new Thread(multiSendThread).start();
break;
case R.id.btnReceive:
if (multiReceiverThread == null) {
multiReceiverThread = new MultiReceiverThread();
}
new Thread(multiReceiverThread).start();
break;
}
}

手机网页上语音实时通话,请问怎么实现,不是下软件,而是使用api
作为独立开发者或想缩短音视频开发周期的公司来说语音通讯api，想要在Android平台下实现音视频通信语音通讯api，最快捷的方法是寻找开源项目或调用其语音通讯api他公司API。之所以这么说是因为音视频通信技术涉及到底层音视频采集、解码、 FFmpeg（音视频处理解决方案）、媒体流传输协议等太多太多相关技术知识点。试了 几个开源项目，视频差强人意，语音与视频不同步等不稳定因素。因此语音通讯api我把目光放到其他公司的API上（点击-demo程序）。demo程序API提供了一系列纯Java语言的调用接口，通过JNI即可调用内核共享库（.so 类似win32 的dll），根据官方开发文档我很快就实现音视频通信，下面是我在调用其API的经验总结
