我有一个问题，使用 Upnp 将视频文件发送到带有 java/android 的 Xbox 一。

我使用cling api通过网络发现和连接 upnp 设备。发现操作运行良好，检测到 xbox one。问题是当我尝试将视频链接发送到此设备时。

在这里，它是对 upnp 连接服务的 Xbox 响应：

如api 文档中所述，您必须首先向设备发送一个 SetAVTransportURI 操作，以提供视频文件的 url：

4.2. Controlling a renderer
Cling Support provides several action callbacks that simplify creating a     control point for the AVTransport service. This is the client side of your     player, the remote control.

This is how you set an URI for playback:

ActionCallback setAVTransportURIAction = new SetAVTransportURI(service, "http://www.duorimes.siquiere.fr/wa_files/Il_20camino.flv", "NO METADATA") {
            @Override
            public void failure(ActionInvocation invocation, UpnpResponse     operation, String defaultMsg) {
                // Something was wrong
        }
    };
This is how you actually start playback:

ActionCallback playAction = new Play(service) {
            @Override
            public void failure(ActionInvocation invocation, UpnpResponse     operation, String defaultMsg) {
                // Something was wrong
            }
        };

就我而言，第一个操作向我发送 500 错误代码（内部服务器错误）

有人遇到过同样的问题吗？

提前感谢您的帮助。

对于SetAVTransportURI, meta 必须按照XMLDLNA 规范的定义进行编码。

在SetAVTransportURI(service, "http://www.duorimes.siquiere.fr/wa_files/Il_20camino.flv", "NO METADATA"),"NO METADATA"是非法XML字符串。

尝试使用空字符串""或生成您自己的元 XML 可能会有所帮助。
