I need to display an RTSP stream using the gst-play-1.0 and/ or gst-launch-1.0 commands on an NVIDIA Jetson-AGX device.
These are the commands I have tried so far:
1. gst-play-1.0
$ gst-play-1.0 rtsp://192.168.1.xxx:8554/main.264
in which case the terminal remains stuck at:
Press 'k' to see a list of keyboard shortcuts.
Now playing rtsp://192.168.1.xxx:8554/main.264
Pipeline is live.
Opening in BLOCKING MODE
NvMMLiteOpen : Block : BlockType = 261
NVMEDIA: Reading vendor.tegra.display-size : status: 6
NvMMLiteBlockCreate : Block : BlockType = 261
Prerolled.
2. gst-launch-1.0
$ gst-launch-1.0 rtspsrc location=rtsp://192.168.1.xxx:8554/main.264 latency=0 buffer-mode=auto ! queue ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! videoscale ! video/x-raw,width=1920,height=1080 ! autovideosink
in which case the terminal remains stuck at:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

The URLs are typically of the following formats:
rtsp://192.168.1.xxx:8554/main.264
rtsp://username:[email protected]:554
I am able to use the commands on a x86 PC with Ubuntu 20.04 and Gstreamer 1.16.3. So, the camera feeds themselves are fine.
But, the commands don't work on the Jetson device.
NVIDIA Jetson-AGX device info:
L4T 32.6.1 [ JetPack 4.6 ]
Ubuntu 18.04.6 LTS
Kernel Version: 4.9.253-tegra

Thanks for going through the post. Any hint(s) or guidance would be most appreciated.
Thank you. :)
Edit: I tried the following command, as suggested by @SeB:
gst-launch-1.0 rtspsrc location=rtsp://username:[email protected]:554 latency=500 ! queue ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! 'video/x-raw(memory:NVMM),width=1920,height=1080' ! nvvidconv ! autovideosink
and the terminal displayed the following:

Thanks for taking an interest in my query.
I also posted the query on NVIDIA's official forum(answer) as well as consulted some other people.
It seems that these two commands should work:
$ gst-launch-1.0 rtspsrc location=rtsp://username:[email protected]:554 latency=500 ! queue ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! 'video/x-raw(memory:NVMM)' ! nv3dsink sync=0
$ gst-launch-1.0 -v uridecodebin uri=rtsp://username:[email protected]:554 ! nvvidconv ! nvegltransform ! nveglglessink
Basically, it is recommended to use NVIDIA specific GStreamer plugins(prefixed by nv) on Jetson devices.
