我正在尝试直接连接到 IP 视频服务器(“Nuuo”IP 服务器)的视频流。
他们的说明手册给出了“主页”的 URL——一个安装了一个可爱的小 activeX 控件的页面,该控件处理与实际视频服务器的所有交互。
我需要该内部服务器的 URL。[我不需要 activeX 控件提供的添加控件,并且处于 Internet Explorer 不可用的环境中。我只想要流]
我尝试了 Wireshark,它捕获了所有数据包,但没有显示不同页面的完整 URL。[即:如果物理设备位于 212.234.56.456,无论我连接到主页(212.234.56.456/home.html)还是连接到视频服务器(可能类似于 212.234.56.456/video.amp),它都会显示相同的 URL ),或设备内的任何其他内容。]
尽管头疼并搜索了他们的网站和手册,但我无法理解如何获取服务器的整个 URL。
有人可以指导我到教程或说明页面 - 或者只是说明如何做到这一点?
Wireshark 不一定是解决方案 - 我会很乐意使用其他东西(尝试过 Fiddler,但不知道配置它 - 默认情况下它不会捕获任何此类流量)
谢谢
编辑:协议是 TCP
视频端口:8000 [服务器中有一个选项可以更改端口。默认为 8000]
我正在尝试使用 VLC 或 RealPlayer [为了重新流式传输] 之类的东西而不是它附带的 activeX 控件连接到视频流。除了它出现在附加的数据包中之外,我对 TCP 一无所知。服务器正在编码为 MPEG 4 [h.264],并且应该是流式传输 RTSP://
我读过很多人使用 Axis 服务器(他们使用 VLC 连接到 rtsp://[server-ip-address]:554/axis-media/media.amp)和 Arecont 服务器(rtsp ://[服务器 IP 地址]/h264.sdp)。显然,这个页面在我使用的 Nuuo 服务器上是不存在的,它是为了和 Axis 设备竞争而设计的。
我加载了页面,启动了 Wireshark,然后按下了 ActiveXControl 上的播放按钮(开始播放视频)。下面是 Wireshark 捕获的第一个数据包 [在许多数据包中,它是对视频的请求]:
