我正在尝试通过网络传输我的网络摄像头信号，但接收客户端无法查看并收到错误：“VLC 无法打开 MRL。”我尝试按照以下说明操作这里。
我尝试在关闭 Windows 7 Enterprise 防火墙的情况下使用 HTTP 作为目标在本地执行此操作。我使用端口 8082 上的 HTTP 目标创建了流，并选中了“本地显示”。我将 http 端口设置为 8082。我可以在这里很好地看到我的相机供稿。
我打开了另一个 VLC 实例来查看流并指向http://127.0.0.1:8082，但收到错误消息：“VLC 无法打开 MRL‘ http://127.0.0.1:8082’。请查看日志了解详细信息。”

答案1
并选中“本地显示”
取消选中此项即可实现目标
答案2
尝试在摄像机的 IP 后输入流文件的名称 - 例如 videostream.asf，例如：
> http://127.0.0.1/videostream.asf
我不知道您使用的是 GUI 还是 CLI，但如果是 GUI，则添加文件名应该会提示您在新弹出窗口中输入密码和用户名。使用 CLI 有点棘手……
