manager.setDiscoveryTimeout(10000); manager.discover(new DiscoveryListener() { Override public void onDiscoveryStarted() { // 发现过程开始 } Override public void onDevicesFound(ListDevice devices) { // 发现设备后的处理逻辑 for (Device device : devices) { System.out.println(发现设备: device.getHostName()); } } });这种设计避免了UI线程阻塞特别适合Android应用和需要高响应性的企业级系统。核心功能模块详解设备发现机制ONVIF-Java支持两种设备发现模式ONVIF WS-Discovery和UPnP协议。WS-Discovery使用UDP端口3702和组播地址239.255.255.250而UPnP使用UDP端口1900。库内部通过DiscoveryThread实现多播包的发送和接收自动处理网络接口的枚举和广播地址的获取。// 指定发现模式 DiscoveryManager manager new DiscoveryManager(); // 使用ONVIF模式发现 manager.discover(DiscoveryMode.ONVIF, discoveryListener); // 或使用UPnP模式发现 manager.discover(DiscoveryMode.UPnP, discoveryListener);设备管理APIOnvifManager类提供了完整的设备管理功能包括获取服务列表、设备信息、媒体配置文件和流媒体URIOnvifManager onvifManager new OnvifManager(); OnvifDevice device new OnvifDevice(192.168.1.100, admin, password); // 获取设备服务端点 onvifManager.getServices(device, new OnvifServicesListener() { Override public void onServicesReceived(OnvifDevice device, OnvifServices services) { // 解析设备支持的服务端点 String mediaServicePath services.getProfilesPath(); String streamingServicePath services.getStreamURIPath(); } }); // 获取设备基本信息 onvifManager.getDeviceInformation(device, new OnvifDeviceInformationListener() { Override public void onDeviceInformationReceived(OnvifDevice device, OnvifDeviceInformation info) { System.out.println(制造商: info.getManufacturer()); System.out.println(型号: info.getModel()); System.out.println(固件版本: info.getFirmwareVersion()); } });媒体流处理媒体流处理是视频监控系统的核心功能ONVIF-Java通过分层设计简化了复杂的媒体配置功能层次对应类主要职责媒体配置OnvifMediaProfile存储媒体配置文件信息流请求GetMediaStreamRequest构建获取流地址的SOAP请求流解析GetMediaStreamParser解析流媒体URI响应流监听OnvifMediaStreamURIListener处理流地址获取结果// 获取媒体配置文件并请求流地址 onvifManager.getMediaProfiles(device, new OnvifMediaProfilesListener() { Override public void onMediaProfilesReceived(OnvifDevice device, ListOnvifMediaProfile profiles) { if (!profiles.isEmpty()) { OnvifMediaProfile mainProfile profiles.get(0); // 获取主码流的RTSP地址 onvifManager.getMediaStreamURI(device, mainProfile, new OnvifMediaStreamURIListener() { Override public void onMediaStreamURIReceived(OnvifDevice device, OnvifMediaProfile profile, String uri) { // RTSP流地址示例: rtsp://192.168.1.100:554/stream1 System.out.println(媒体流地址: uri); } }); } } });企业级应用场景实践大规模设备管理系统在大型安防项目中通常需要管理数百甚至数千台摄像头。ONVIF-Java的异步架构非常适合这种场景public class CameraManagementSystem { private ListOnvifDevice discoveredDevices new ArrayList(); private ExecutorService deviceExecutor Executors.newFixedThreadPool(10);

// 2. 获取流地址 manager.getMediaStreamURI(dev, profile, (d, p, uri) - { // 3. 启动视频流处理 VideoStream stream new VideoStream(uri); activeStreams.put(cameraId, stream); stream.start(); // 4. 添加视频分析处理器 stream.addProcessor(new MotionDetectionProcessor());
