镜头调焦和聚焦之前我们说过，一个使用的ptz能力，一个使用的imaging能力，而预置点使用的还是使用的ptz能力。

//注意这里的typemap.dat是上节我们修改过的，不然还会出现duration.c编译报错
wsdl2h -c -t ./typemap.dat -o onvif.h http://www.onvif.org/onvif/ver10/network/wsdl/remotediscovery.wsdl https://www.onvif.org/ver10/device/wsdl/devicemgmt.wsdl https://www.onvif.org/ver10/events/wsdl/event.wsdl https://www.onvif.org/ver10/media/wsdl/media.wsdl https://www.onvif.org/ver20/ptz/wsdl/ptz.wsdl https://www.onvif.org/ver20/imaging/wsdl/imaging.wsdl
vim onvif.h
添加 #import "wsse.h"
//需要依赖如下文件，从gSoap源码拷贝到我们的工程中（拷贝一次后续就可以一直用了）
dom.c、dom.h、wsseapi.c、wsseapi.h、smdevp.c、smdevp.h、mecevp.c、mecevp.h、threads.c、threads.h、wsaapi.c、wsaapi.h
//注意下面的文件需要custom文件夹，否则路径不对
struct_timeval.h、struct_timeval.c
//duration.c以及duration.h对于生成框架代码和编译c代码路径可能会有差异，根据实际情况可能需要两个位置都有
//只生成客户端源文件，我们只实现客户端，不添加-C会多生成服务端代码
soapcpp2 -x -L -C onvif.h
整个过程截图：
由于缩放也是在ptz的，所以我们在上节的ptz基础上增加两个值来进行缩、放控制指令zoom下发。
focus单独使用img能力调用接口进行move和stop，此外，focus还需要videoSourceToken，这个token不同于profileToken，但是获取方式类似，所以还需要增加videoSourceToken获取的实现。
预置点的接口虽然也是使用的ptz能力，但是接口和ptz控制的接口不同，所以我们也单独再封装接口做增删改查及预置点跳转。

目前来说，暂时用到的onvif客户端相关的内容就这些了，其它的可能是在此基础上扩展音视频编解码或者CV算法调用等，接下来我可能会将这部分内容借助H5做一个简单的摄像头控制页面，和Go做简单的前后端调用，看下h5如何通过rtsp流来实时播放视频，并看下如何在一定程度上降低延迟，再之后我们可能会去总结一些CV的东西，比如OpenCV如何使用，如何和onvif结合使用，如何在手机上、PC上结合Qt等来开发软件使用，对于一些没有人脸识别的手机，我们如何自己做一个人脸识别的软件来做简单的代替或者使用人脸登录配合传统的用户名密码登录等等（ps:前面鸽的stm32的开发总结说实话我还没想好啥时候继续，最近有个嵌入式中级考试，可能会先总结这块，估计也得个大半年甚至一年）
