If you can play from other Linux hosts but not from Jetson, there should be a reason. This is what I’m trying to help to figure out.
Are you able to read other RTSP streams from your Jetson such as this one ?
gst-launch-1.0 rtspsrc location=rtspt://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov ! fakesink
Also, try increasing rtspsrc log level as in my previous post, get the ouput into a txt file and upload it here.
