x265enc: problem with framerate=0/1 when re-encoding from rtp

Description

Hello!

I'm receiving a raw RTP stream as an input and I wanted to encode it and streaming it again through RTP.

I was using this command to do it encoding to h264 and it was working just great:

gst-launch-1.0 udpsrc port=9001 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW, sampling=(string)YCbCr-4:2:0, depth=(string)8, width=(string)1280, height=(string)960, framerate=25/1, payload=(int)111" ! rtpvrawdepay ! x264enc bitrate=16384 ! rtph264pay ! udpsink host=127.0.0.1 port=1234

Now, i'm trying to encode to h265 and everything just stopped working. The command i'm using is:

gst-launch-1.0 udpsrc port=9001 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW, sampling=(string)YCbCr-4:2:0, depth=(string)8, width=(string)4096, height=(string)2048, framerate=30/1, payload=(int)111" ! rtpvrawdepay ! x265enc bitrate=16384 ! rtph265pay ! udpsink host=127.0.0.1 port=1234

But now everything just stopped working and it returns:

Everything looks okay appart the framerate that is set to 0 (variable). Do you have any idea of what could be happening?

Thanks.
