Nv4l2h265decoder 0/1 framerate

I am trying to build a pipeline that receives a h265 enconded stream (udpsrc ! rtph265pay ! nv4l2h265decoder ! queue ! tee name=t ! appsink t. ! “webrtc stuff”), sent by another gstreamer pipeline, in a udpsrc, decodes it and pushes it to an appsink. In the nv4l2h265decoder exit the framerate is 0/1:
