在Gstreamer中使用SRT协议 使用以下两个命令，我可以通过SRT传输videotestsrc源

并以这种方式播放：

gst-play-1.0 srt://127.0.0.1:8888

现在，我想流式传输一个rtsp源，我通过以下方式获得它：

但是，当我在播放时出现以下错误：

gst-play-1.0 srt://127.0.0.1:8888

Press 'k' to see a list of keyboard shortcuts.
Now playing srt://127.0.0.1:8888
Pipeline is live.

Reached end of play list.

我怎样才能解决它
