What do you mean by "works perfectly" here? That it doesn't complain or
error out, or that the resulting mp4 file plays just fine afterwards?

It appears there's a problem with packet loss or reordered packets
here. Maybe nvh265dec has a start-up delay that blocks the udpsrc for a
bit too long (that's just speculation).

Have you tried putting a queue after udpsrc, like

 udpsrc ! queue max-size-time=0 max-size-buffers=0 max-size-bytes=0

or even better an rtpjitterbuffer like

 udpsrc ! rtpjitterbuffer latency=100 ! ..
