Hi,
Please share a gst-launch command to reproduce the issue. Are you on r32.1?

Hi Dane,

Yes, r32.1

my gst-launch command :

OK ==> gst-launch-1.0 filesrc location=4k.265 ! h265parse ! nvv4l2decoder disable-dpb=1 ! nv3dsink sync=0

FAIL ==> gst-launch-1.0 udpsrc port=5000 ! tsdemux ! h265parse ! nvv4l2decoder disable-dpb=1 ! nv3dsink sync=0

FAIL ==> gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H265,payload=96 ! rtph265depay ! video/x-h265 ! nvv4l2decoder disable-dpb=1 ! nv3dsink sync=0

After remove the element properties, it works well.
