Hi,
I'm using test-multicast.c to try and understand how to multicast an H.264
stream.
I have not modified the example.
I cannot receive the stream on my client.
GStreamer v1.14.5. Ubuntu 18.04.
gst-launch-1.0 -v rtspsrc location="rtsp://127.0.0.1:8554/test" !
rtph264depay ! avdec_h264 ! autovideosink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

*ERROR: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0: No
supported stream was found. You might need to allow more transport protocols
or may otherwise be missing the right GStreamer RTSP extension plug-in.*
Additional debug info:
gstrtspsrc.c(7052): gst_rtspsrc_setup_streams_start ():
/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0
ERROR: pipeline doesn't want to preroll.

Setting pipeline to READY ...
Setting pipeline to NULL ...

I have also tried VLC: rtsp://@127.0.0.1:8554/test but to not avail.
I can see the SETUP at 224.3.0.0 and can see multicast packets being sent to
that address, but VLC is not showing any video.
Any pointers as to what I might be doing wrong?
