SRT Streaming Issues with GStreamer on Jetson Orin NX

Dear all,

I am using a Jetson Orin NX board with Jetpack 5.1.2 and GStreamer 1.16.3 installed. My task is to send video from the camera mounted on the Orin NX board to a mediamtx server via RTMP using GStreamer, and then play the video on an Ubuntu 20.04 laptop console using SRT with GStreamer.

Initially, I confirmed that communication via RTMP and RTSP using GStreamer worked well, and the video output was good. However, I am consistently encountering error messages when using SRT. The port number for SRT on the mediamtx server is 8890.

Here is the command and error message:

$ gst-launch-1.0 -v srtsrc uri="srt://board_ip_address:8890?streamid=read:mystream" ! queue ! decodebin ! videoconvert ! autovideosink
Setting pipeline to PAUSED ...

11:01:18 AM.773645/SRT:RcvQ:worker*E:SRT.c: RendezvousQueue: processAsyncConnectRequest FAILED. Setting TTL as EXPIRED.

I have tried various methods for a week to resolve this issue.

First, I confirmed that the video output worked well when using VLC with the URI ‘srt://board_ip_address:8890?streamid=read’.

Since GStreamer 1.16.3 was installed with Jetpack 5.1.2, I am worried that upgrading to a more recent version might cause compatibility issues. I attempted to install GStreamer 1.20.3 using meson and ninja, but GStreamer 1.16.3 remained on the system, so I eventually uninstalled GStreamer 1.20.3.

When I used FFmpeg for SRT communication, the video output was good. Therefore, it does not seem to be a network configuration issue, but rather a problem specifically with GStreamer.

Is there any way to resolve this issue? Should I upgrade to a newer version of GStreamer? If I do, will there be any compatibility issues with Jetpack 5.1.2?

I urgently need help with this.

Thank you in advance.

Hi,
We don’t have much experience in enabling SRT. Would see if other users can share experience.

The Jetpack 6.0GA release is with gstreamer 1.20.3. If you have developer kit(Orin Nx module + Orin Nano carrier board), may consider flash to the version and give it a try.
