问题描述
我在这里遇到有关ONVIF IP摄像机规范的麻烦.我建立了一个程序，可以使用该标准来联系相机并将其发送给标准媒体/设备请求.
I'm in trouble here about the ONVIF IP Camera specification. I've built a program that is able to use the standard to contact cameras and send them standard media/device requests.
问题是我现在正在尝试通过ONVIF访问其PTZ容量，而对于我的两个摄像机，我只会遇到以下错误:
The problem is that I'm now trying to access their PTZ capacities through the ONVIF and that for both of my cameras, I only get this following error :
HTTP/1.1 400 Bad Request
Content-Type: application/soap+xml; charset=utf-8
Content-Length: 741

因此，名称空间错误.
问题是我通过GetCapabilities()ONVIF请求获得了摄像机(/onvif/ptz_service)的onvif PTZ命名空间.
The problem is that I got the onvif PTZ namespace of the camera (/onvif/ptz_service) through a GetCapabilities() ONVIF request.
对于我发送到两个ONVIF摄像机中的任何一个的任何PTZ onvif请求，问题都是相同的.
The problem is same for any PTZ onvif request that I send to any of both of my two ONVIF cameras.
我已经尝试使用ONVIF查找软件，以使它们发送PTZ请求并查看它们是否有效，但是我没有找到一个(这里有一个ONVIF设备管理器: http://sourceforge.net/projects/onvifdm/，但是没有实际的PTZ处理，除非问题出自我的相机).
I already tried to find softwares using the ONVIF to have them send PTZ request and see if they works, but I didn't find one (There's an ONVIF Device Manager here : http://sourceforge.net/projects/onvifdm/ but there's no actual PTZ handling, unless the problem come from my cameras).
推荐答案
我发现了这个问题，坦率地令人失望:
I found the problem, which is frankly disappointing :
我使用的是ONVIF PTZ WSDL文件的第2版(ver20)，因为第1版(ver10)被认为已弃用.
I was using the 2nd version (ver20) of the ONVIF PTZ WSDL file, because the 1st one (ver10) is considered as deprecated.
即使是我几天前刚购买的，具有最新固件的ONVIF相机，也仍在使用ver10.
Turns out even the recent ONVIF camera I just bought some days ago, with an up-to-date firmware, is still using ver10.
由于无法使用SvcUtil使用ver10 wsdl生成代理类，因此我尝试使用ver10(而不是ver20)切换所有"http://www.onvif.org/ver20/ptz/wsdl"命名空间，并且有用.目前.我希望它将继续与其他相机配合使用...
Since I can't use SvcUtil to generate my proxy class using the ver10 wsdl, I tried switching all the "http://www.onvif.org/ver20/ptz/wsdl" namespaces with ver10 instead of ver20, and it works. For now. I hope it'll keep working with other cameras ...
