correct

[2] works, [4] doest not work

I did not try, but since [2] works, I guess so

I have no video on this remote vm.

From what I have read about the udpsink in the gst-inspect, it looks like it is pushing the stream to 'host', so I do not think I can get this to work, since I am testing with a local (windows) vlc and a remote vm. I think the problem must be somewhere between demux  and mux, maybe some 'header' or other setting is being removed, and that is why vlc has problems with 'detecting' the live stream.
