我需要在 NVIDIA Jetson-AGX 设备上使用 gst-play-1.0 和/或 gst-launch-1.0 命令显示 RTSP 流。
这些是我迄今为止尝试过的命令：
1。 gst-播放-1.0
$ gst-play-1.0 rtsp://192.168.1.xxx:8554/main.264
在这种情况下，终端仍然卡在：
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
在这种情况下，终端仍然卡在：

URL 通常采用以下格式：
rtsp://192.168.1.xxx:8554/main.264
rtsp://username:[email protected]:554
我可以在装有 Ubuntu 20.04 和 Gstreamer 1.16.3 的 x86 PC 上使用这些命令。所以，相机本身就很好。
但是，这些命令在 Jetson 设备上不起作用。
NVIDIA Jetson-AGX 设备信息：
L4T 32.6.1 [JetPack 4.6]
Ubuntu 18.04.6 LTS
内核版本：4.9.253-tegra
GStreamer 1.14.5

感谢您浏览该帖子。任何提示或指导将不胜感激。
谢谢你。 :)
编辑： 我按照@SeB的建议尝试了以下命令：
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
终端显示如下：

感谢您对我的询问感兴趣。
我也在NVIDIA的官方论坛上发布了这个问题（answer），也咨询了一些其他人。
看来这两个命令应该有效：
$ 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
基本上，建议在 Jetson 设备上使用 NVIDIA 特定的 GStreamer 插件（前缀为 nv）。
