Hikvision IP Camera Android开发

本文主要是介绍Hikvision IP Camera Android开发，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Hikvision Android开发

Search 设备

Hikvision 的设备都是采用UPNP协议来进行设备发现的。

组播IP: 239.255.255.250 端口号:37020

组播数据示例:

<?xml version="1.0" encoding="utf-8"?><Probe><Uuid>538a7d46-ed57-30a0-88d9-3b3ad93a761b</Uuid><Types>inquiry</Types></Probe>

 private void postSearchPacket() {Thread postThread = new Thread(new Runnable() {@Overridepublic void run() {try {InetAddress address = InetAddress.getByName("239.255.255.250");byte[] buffer = ScanPacket.packetData(createUUID(mContext));DatagramPacket packet = new DatagramPacket(buffer, buffer.length, address, IPCAM_PORT);DatagramSocket socket = new DatagramSocket();socket.setReuseAddress(true);socket.send(packet);socket.close();Log.d(TAG, "post search packet");} catch (UnknownHostException e) {e.printStackTrace();} catch (SocketException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}});postThread.start();}

接受IP Camera 广播的数据数据示例：

接受代码

private void createReceiverThread() {Thread receiverThread = new Thread(new Runnable() {@Overridepublic void run() {byte[] buffer = new byte[BUFF_SIZE];DatagramPacket inPacket;try {InetAddress address = InetAddress.getByName("239.255.255.250");MulticastSocket socket = new MulticastSocket(RECEIVER_PORT);socket.setReuseAddress(true);socket.joinGroup(address);inPacket = new DatagramPacket(buffer, BUFF_SIZE);Log.d(TAG, "Receiver socket created");while (isEnableReceiver()) {socket.receive(inPacket);Log.d(TAG, "Receiver hikvision data");Camera cam = ReceiverPacket.parse(buffer, inPacket.getLength());if (cam != null) {addCamera(cam);if (mCallBack != null) {Log.d(TAG, "call onSearchFinished");mCallBack.onSearchFinished(mCameraList);} else {Log.e(TAG, "mCallBack is null");}} else {Log.e(TAG, "parse failed!");sleep(100);}}socket.close();} catch (Exception e) {e.printStackTrace();}}});receiverThread.start();}

解析代码

public class ReceiverPacket {private int vcode_1 = 0;private int vcode_2 = 0;private static final String DeviceDescription = "<DeviceDescription>(.*?)</DeviceDescription>";private static final String DeviceSN = "<DeviceSN>(.*?)</DeviceSN>";private static final String CommandPort = "<CommandPort>(.*?)</CommandPort>";private static final String HttpPort = "<HttpPort>(.*?)</HttpPort>";private static final String IPv4Address = "<IPv4Address>(.*?)</IPv4Address>";private static final String Activated = "<Activated>(.*?)</Activated>";private static final String PacketTagStart = "<ProbeMatch>";private static final String PacketTagEnd = "</ProbeMatch>";public static Camera parse(byte[] data, int len) {Camera ret = null;if ((data != null) && (len > 0)) {String content = null;String tmp = new String(data, 0, len);Log.d("====test====", "tmp=" + tmp);if (tmp != null) {int start = tmp.indexOf(PacketTagStart);int end = tmp.lastIndexOf(PacketTagEnd);if ((start >= 0) && (end >= 0)) {content = tmp.substring(start + PacketTagStart.length(), end);}}if (content != null) {ret = new Camera();ret.name = findValue(DeviceDescription, tmp);ret.ip = findValue(IPv4Address, tmp);ret.sn = findValue(DeviceSN, tmp);if (ret.sn != null) {if (ret.sn.length() > 9) {ret.id = ret.sn.substring(ret.sn.length() - 9);} else {ret.id = ret.sn;}}ret.port_rtsp = 554;try {ret.port_http = Integer.parseInt(findValue(HttpPort, tmp));ret.port_command = Integer.parseInt(findValue(CommandPort, tmp));} catch (Exception e) {e.printStackTrace();}Log.d("====test====", "parse success!");}return ret;} else {return null;}}private static String findValue(String matcher, String source) {String ret = null;Matcher valueMatcher = Pattern.compile(matcher).matcher(source);if (valueMatcher.find()) {ret = valueMatcher.group(1);}return ret;}

通过以上步骤，我们可以获取IP camera 的IP，端口号，id，sn等信息。再根据以上信息去跟IP camera通讯

IP camera 的rtsp流播放

rtsp://<user>:<password>@" + cam.ip +":554" + "ch1/<main/sub>/av_stream
注意：1. user和password 是指登录ipcamera 的用户名和密码2. main表示主码流, sub表示子码流3. ch1表示通道，一般默认为ch1

ISAPI通讯接口

Hikvision本身有一个SDK，用于集成到Windows或者Linux，也可以集成到Android的上面，就是在Linux的库上面再做个封装，引出jni类型的API，我自己因为使用的接口比较少，然后读取SDK的文档的时候发现其实还有一个ISAPI的用于web的接口，于是就从网络上下载ISAPI接口的文档，然后在Android中直接调用ISAPI。
