Tcp 无法使用Live555代理服务器传输RTSP

我正在使用Live555流媒体应用程序记录和重新流式传输来自IP摄像头的RTSP流。为此，我使用openRTSP进行录制，使用live555代理服务器重新流式传输相机流。对于一些摄像机，我们面临一个奇怪的问题，即摄像机录制成功，但是live555代理服务器无法为同一摄像机流生成新的流（详细输出转储中没有失败的迹象，但是rtsp客户端无法解码代理服务器生成的rtsp url）. 由于我对live555代理服务器的详细信息一无所知，所以我一直无法解决这个问题。我试着用VLC传输相同的摄像机流，效果很好。这可能有什么问题。我在此附上详细的输出以供参考

这可能主要是因为防火墙阻塞了udp端口。尝试使用

-t

标志强制通过tcp进行传输

你使用tcp传输吗？如果是，请尝试使用udp传输。
