Hi all,
after launched the test-launch in gst-rtsp-server, I can watch the stream successfully. But if there is one more client access to the stream, both clients freezes, event the setshared is on. May I know how to have multiple clients for the rtsp server with live videos? Thanks
Hi,
Please share which source is in the pipeline. Some sources are not able to support the function. It should work with videotestsrc or filesrc.
$ ./test-launch "videotestsrc ! nvvidconv ! nvv4l2h264enc ! h264parse ! rtph264pay name=pay0 pt=96"
I have tried your command with no success.
I have the following log:
stream ready at rtsp://127.0.0.1:8554/video_feed0

Update is that:
Using the same test-launch, multi-client streaming works in my ubuntu 18.04 with gstreamer 1.18 desktop…
Hi,
We can launch RTSP server on JP4.5/Xavier and have multiple clients(from a Ubuntu PC and a Windows PC) successfully. What is your L4T release version?
R32 (release), REVISION: 4.4, GCID: 23942405, BOARD: t186ref, EABI: aarch64, DATE: Fri Oct 16 19:37:08 UTC 2020
jetpack 4.4.1
Hi,
Do you run a different pipeline? In the log, there is link failure with appsrc plugin. This should not be present if you use videotestsrc plugin.
I am able to have multi-clients with videosrc and filesrc after flashing with jetpack 4.5.1
You mentioned that not all src can have multi-clients
My case is images generated by opencv, and push to appsrc by gst-buffer with call back function on_need_data.
Is that appsrc supported for multiclient stream? Thank you very much.
Hi,
We are not sure if it is supported with appsrc. Suggest you try the reference sample with multi-clients:
gst-rtsp-server/test-appsrc.c at master · GStreamer/gst-rtsp-server · GitHub
If it works, you may refer to the sample for developing your usecase. And may go to gstreamer forum to get further suggestion.
