Java onvif协议通用协议获取rtsp地址

Java onvif协议通用协议获取rtsp地址

吐槽下可搜索的资源真的是少，好多都是4 5年前的资料

onvif通用协议就不说了，大多摄像头都可用，利用onvif获取实时流和历史流转换成h264编码推送到前端，用h5新标签直接播放

onvif协议大部分是c或者android 资料 java的比较少 感谢大佬留下的宝贵资源：

1. https://github.com/RootSoft/ONVIF-Java   (功能不够完善，没有使用例子)

2. https://github.com/fpompermaier/onvif   (这个是基于上面的项目封装，有简单的例子，这里使用的这个)

实际使用：

前言：因为例子有限，没有历史流rtsp地址的使用，在参考例子和源码下，走了很多坑

后续更新利用javacv 使用rtsp地址拉取流推送出去。

上代码：

将第二个项目拉下来打包到本地仓库 下面的

pom 中的onvif-ws-client就是打包到本地仓库的

项目地址：https://github.com/xsjzf/onvif_java

核心的地方是：

这里说明下例子中只有实时流rtsp地址的方法获取

在onvif-ws-client的源码中有很多功能例子中只有media 也就是实时流的

要使用历史流则需要自行添加 就是replay和recording 其他功能详见onvif的官网文档

Capabilities capabilities = this.device.getCapabilities(Arrays.asList(CapabilityCategory.ALL));

@javax.xml.bind.annotation.XmlElement(name = “Analytics”)

protected org.onvif.ver10.schema.AnalyticsCapabilities analytics;

@javax.xml.bind.annotation.XmlElement(name = “Device”)

protected org.onvif.ver10.schema.DeviceCapabilities device;

@javax.xml.bind.annotation.XmlElement(name = “Events”)

protected org.onvif.ver10.schema.EventCapabilities events;

@javax.xml.bind.annotation.XmlElement(name = “Imaging”)

protected org.onvif.ver10.schema.ImagingCapabilities imaging;

@javax.xml.bind.annotation.XmlElement(name = “Media”)

protected org.onvif.ver10.schema.MediaCapabilities media;

@javax.xml.bind.annotation.XmlElement(name = “PTZ”)

protected org.onvif.ver10.schema.PTZCapabilities ptz;

@javax.xml.bind.annotation.XmlElement(name = “Extension”)

protected org.onvif.ver10.schema.CapabilitiesExtension extension;

OnvifDevice 的init方法中

Capabilities对象里面除了基本的功能大多在Extension里面

@XmlAccessorType(XmlAccessType.FIELD)

@XmlType(name = “CapabilitiesExtension”, propOrder = {

“any”,

“deviceIO”,

“display”,

“recording”,

“search”,

“replay”,

“receiver”,

“analyticsDevice”,

“extensions”

})

public class CapabilitiesExtension {

@XmlAnyElement(lax = true)

protected List any;

@XmlElement(name = “DeviceIO”)

protected DeviceIOCapabilities deviceIO;

@XmlElement(name = “Display”)

protected DisplayCapabilities display;

@XmlElement(name = “Recording”)

protected RecordingCapabilities recording;

@XmlElement(name = “Search”)

protected SearchCapabilities search;

@XmlElement(name = “Replay”)

protected ReplayCapabilities replay;

@XmlElement(name = “Receiver”)

protected ReceiverCapabilities receiver;

@XmlElement(name = “AnalyticsDevice”)

protected AnalyticsDeviceCapabilities analyticsDevice;

@XmlElement(name = “Extensions”)

protected CapabilitiesExtension2 extensions;

例如我这里需要历史流的功能那么我在init方法中初始化添加上

if (capabilities.getExtension().getReplay() != null && capabilities.getExtension().getReplay().getXAddr() != null) {

this.replayPort = new ReplayService().getReplayPort();

this.replayPort =

getServiceProxy((BindingProvider) replayPort, capabilities.getExtension().getReplay().getXAddr())

.create(ReplayPort.class);

}

if (capabilities.getExtension().getRecording() != null && capabilities.getExtension().getRecording().getXAddr() != null) {

this.recordingPort = new RecordingService().getRecordingPort();

this.recordingPort =

getServiceProxy((BindingProvider) recordingPort, capabilities.getExtension().getRecording().getXAddr())

.create(RecordingPort.class);

}

if (capabilities.getExtension().getSearch() != null && capabilities.getExtension().getSearch().getXAddr() != null) {

this.searchPort = new SearchService().getSearchPort();

this.searchPort =

getServiceProxy((BindingProvider) searchPort, capabilities.getExtension().getSearch().getXAddr())

.create(SearchPort.class);

}

具体使用：

/**

* @param host 摄像头地址 92.168.xx.yy, or http://host[:port]

* @param username 用户名

* @param password 密码

* @param profileToken “MediaProfile000” If empty, will use first profile.

* @return

*/

public static OnvifDevice getOnvifCredentials(String host, String username, String password, String profileToken){

try {

OnvifCredentials credentials = new OnvifCredentials(host, username, password, profileToken);

//补全host

URL u = credentials.getHost().startsWith(“http”)

? new URL(credentials.getHost())

: new URL(“http://” + credentials.getHost());

return new OnvifDevice(u, credentials.getUser(), credentials.getPassword());

} catch (MalformedURLException | ConnectException | SOAPException e) {

e.printStackTrace();

throw new RrException(e.getMessage());

}

}

/**

* @return

* @throws Exception

*/

public static String getRtspUrl(OnvifDevice onvifDevice) throws Exception {

List profiles = onvifDevice.getMedia().getProfiles();

for (Profile profile : profiles) {

String profileToken = profile.getToken();

String rtsp = onvifDevice.getStreamUri(profileToken, TransportProtocol.RTSP);

String uri = “rtsp://” + onvifDevice.getUser() + “:” + onvifDevice.getPassword() + “@” + rtsp.replace(“rtsp://”, “”);

}

return “”;

}

/**

* @param onvifDevice 设备

* @return

*/

public static String getReplayUrl(OnvifDevice onvifDevice){

List recordings = onvifDevice.getRecordingPort().getRecordings();

for (GetRecordingsResponseItem recording : recordings) {

String uri = “rtsp://” + onvifDevice.getUser() + “:” + onvifDevice.getPassword() + “@” + rtsp.replace(“rtsp://”, “”);

}

return “”;

}

/**

* @param start 开始

* @param end 结束

* @return ?starttime=20200908t093812z&endtime=20200908t104816z

*/

public static String getRtspTimeSpace(LocalDateTime start, LocalDateTime end){

Long st = start.toInstant(ZoneOffset.of(“+8”)).toEpochMilli();

Long ed = end.toInstant(ZoneOffset.of(“+8”)).toEpochMilli();

String ios8601St = getDate(st);

String ios8601Ed = getDate(st);

return “?starttime=” + ios8601St + “&endtime=” + ios8601Ed;

}

/**

* 时间戳转换成IOS8601格式

* @param beginTime

* @return

*/

public static String getDate(Long beginTime) {

SimpleDateFormat format = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);

String bt = format.format(beginTime);

Date date = null;

try {

date = format.parse(bt);

} catch (Exception e) {

e.printStackTrace();

}

SimpleDateFormat sdf = new SimpleDateFormat(“yyyyMMdd’T’HHmmss’z'”);

return sdf.format(date);

}

这里就会获取到实时流和历史流的rtsp地址 后续文章会使用这个地址实现视频推流
