我正在实现简单的 RTSP 服务器，它应该通过 rtsp 流式传输 mjpeg。当我用一些响应数据进行响应时，我遇到的第一个问题是“挂起”的 RTSP 客户端（我尝试了 vlc 和 openRTSP）：缓冲问题与 java 通信 vlc
但是，这很容易发现问题的根源是在请求结束时错过了双 \r\n 序列。我已经成功编写了 OPTIONS 和 DESCRIBE 的响应，这些响应在客户端上得到了正确处理。
我在尝试实施 SETUP 时遇到了这个问题。当我向 SETUP 输出一些格式正确的 RTSP 响应时，两个 openRTSPvlc 都不会将响应视为完整：

并且在那条消息之后什么也没有发生。我认为，RTP 和 RTCP 在幕后发生了一些事情，但是调试它的方式是什么？VLC 和 openRTSP 没有输出足够详细的信息。
有任何想法吗？
