我有点困惑，我希望你能帮助我。我正在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。
描述： 我的应用程序包含3个模块RTSP，RTP和UI。 跳过UI的描述。 RTSP开始侦听tcp端口55555.然后在VLC中输入rtsp：// address：55555 然后是握手和所有RTSP共享的标头。 Durung共享头文件程序通过RTP设置接收和设置端口，Android应用程序开始发送一些字节但是......
这是问题所在： VLC中没有任何图像。所以我查看了日志和：

我的问题：我是否必须在与RTSP相同的端口上发送流？我指望你的帮助，因为有很多代码要改变。
请原谅我的英语。
答案 0 :(得分：0)
流媒体视频未通过udp到达VLC。 这就是为什么在超时10秒后它会尝试回退并通过tcp接收媒体。 你可以看一下rtp / rtsp / tcp。它是一个允许在与rtsp相同的套接字上发送rtp数据包的协议。
