我正在尝试设置我获得的三个 IP 摄像头，以便在 ZoneMinder 中使用它们。根据摄像头的 Web 界面，可以在以下位置查看流：http://192.168.47.202:8090/live.asf
但是，既然我在这里写，这显然不起作用（至少不使用vlc或avconv）。
avconv说：
[http @ 0x230e9c0] HTTP error 405 Unsupported Service
http://192.168.47.202:8090/live.asf: Input/output error
avconv -v debug没有透露任何新内容。
vlc说：
[0x7f2a680013b8] access_http access error: error: HTTP/1.0 405 Unsupported Service
[0x7f2a680013b8] access_mms access error: cannot read data 2
但是，如果我使用 Windows Media Player（在 VirtualBox 中运行的 WinXP）访问相同的地址，它可以正常工作。
我希望有人能对此事作出一些解释，并给我一些建议，告诉我该如何进行。
编辑：vlc似乎能够连接到相机（它确实发现它被称为 Camera3），但无法播放任何内容......
