我在nginx-rtmp-module上提供了一些rtmp流，它们的数量将动态改变。
但是对于客户端的限制，我必须在rtsp协议中提供服务。显然，nginx-rtmp-module不支持它。所以我打算在同一台设备上运行一个rtsp服务器，然后用rtp流将rtmp流转换成rtsp流，然后将rtsp流发送到rtsp服务器。这样客户端就可以从rtsp服务器播放流。
麻烦的是我找不到一个稳定的服务器，它只接收任何rtsp流并为它们提供服务。
There是一个符合我所有需求的例子，但它有点不稳定。
我以详细模式运行它并使用以下命令发送流：
ffmpeg -i rtmp://localhost/<name> -codec copy -ar 44100 -ac 1 -f rtsp rtsp://localhost:5545/<name>
并播放：
gst-launch-0.10 playbin2 uri=rtsp://<server>/<name>
视频没有出现，并且有一些反复警告：
WARNING: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstRtpVorbisDepay:rtpvorbisdepay0: Could not decode stream.
Additional debug info:

当我尝试：
gst-launch-1.0 playbin uri=rtsp://<server>/<name>
它被卡住了，没有视频出现：

视频出现但质量让我感到压抑。

我不确定ffmpeg或rtsp-server是否有问题，是否有人有想法？
非常感谢。

FFmpeg documentation提及Darwin Streaming Server和Mischa Spiegelmock’s RTSP server（您已尝试过）。
关于您的输出，您有很多 UDP数据包丢失：RTP: missed 6 packets。
如果您尝试在服务器所在的同一本地网络上播放RTSP流，那么这绝对不正常。尝试DSS或检查网络配置/端口。
如果您正在尝试通过Internet上的客户端，那么UDP数据包丢失确实会发生，并且您无能为力。如果您设法找到支持它的服务器和播放器，您可以尝试使用前向纠错（FEC）机制。大多数设备和软件播放器都没有。
