Not opening window when using srtsrc.

Hello.
I compiled newest version and changed the srt verision to 1.3.2 refer to the following Issue.
And I use this command, but not opening window.
gst-launch-1.0 srtsrc uri=srt://(ip):(port)?streamid=xxx ! decodebin ! autovideosink

When I used fakesink, it seemed to be working fine.
And autovideosink is working fine too because it can display videotestsrc.

I'm using this project for server application.

What should I do next?
Thanks.
