ffmpeg - 是否有媒体服务器只接收任何 rtsp 流并为它们提供服务？

Question

我有一些通过 nginx-rtmp-module 提供的 rtmp 流，它们的数量将动态更改。

但是为了客户端的限制，我必须在 rtsp 协议(protocol)中为他们服务。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，用ffmpeg将rtmp流转换成rtsp流，然后将rtsp流发送到rtsp服务器。这样客户端就可以播放来自 rtsp 服务器的流。

问题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是一个适合我所有需要的例子，但它有点不稳定。

我以详细模式运行它并发送流:

ffmpeg -i rtmp://localhost/<name> -codec copy -ar 44100 -ac 1 -f rtsp rtsp://localhost:5545/<name>

并通过以下方式播放流:

gst-launch-0.10 playbin2 uri=rtsp://<server>/<name>

视频没有出现，并且有一些重复的警告，如下所示:

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>

它卡住了，没有视频出现:

当我玩:

ffplay rtsp://<server>/<name>

视频出现了，但质量让我很沮丧。

这是输出:

我不确定 ffmpeg 还是 rtsp-server 是问题所在，有人有什么想法吗？

非常感谢。

Answer 1

FFmpeg documentation提到Darwin Streaming Server和 Mischa Spiegelmock’s RTSP server (您已经尝试过)。

关于您的输出，您有很多 UDP丢包 : 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，那么这绝对是不正常的。尝试 DSS 或检查网络配置/端口。

如果您在 Internet 上的客户端上尝试，那么 UDP 数据包丢失确实会发生，您无能为力。您可以尝试使用 前向纠错 (FEC) 机制，如果您设法找到支持它的服务器和玩家。大多数设备和软件播放器都没有。
