我有点困惑，希望你能帮助我。我在Android上编写rtsp服务器。我遇到了一些问题，但有一些方法可以解决所有问题，除了一个问题。发送与RTSP相同的端口上的RTP包
描述： 我有一个应用程序由3个模块RTSP，RTP和UI组成。 跳过UI的描述。 RTSP开始监听tcp端口55555.然后在VLC I中输入rtsp：//地址：55555 然后是握手和头部的所有RTSP共享。 Durung共享头文件程序集通过RTP和Android应用程序设置接收和设置端口开始发送一些字节，但...
这里是问题： VLC中没有任何图像。所以我看着日志和：

而我的问题：我必须发送与RTSP相同的端口上的流吗？我依靠你的帮助，因为有很多代码需要改变。
请原谅我的英语。
RTP和RTSP端口可以而且必须是不同的，没有错。你如何发送/接收流？请粘贴一些代码。 – 1615903
“live555警告：10秒内没有收到数据。切换到TCP”这一行是日志，告诉UDP数据没有被vlc接收。你可以检查UDP端口是否打开。还要检查服务器生成的SDP响应，SDP中的端口应与传输数据的端口相同。 – rajneesh
通过RTSP协商我的服务器和vlc客户端设置trasport端口和服务器端口，所以我认为vlc端口是开放的。连接设置在我的局域网中，并且没有防火墙问题。 另一方面，我发送SDP作为内容。我认为这是正确的，因为最终建立连接。你能告诉我我到底需要投入SDP内容吗？ – adrian
