I want use nvvidconv to scale video size ,but result is crop ,why?

Accelerated Computing Intelligent Video Analytics DeepStream SDK

! 'video/x-raw, format=(string)RGBA, width=(int)960, height=(int)540' \

! rtph264pay config-interval=1 pt=96 mtu=4096 \
! udpsink host=10.0.0.2 port=5000

this is success, but

  1. I need scale, but result is crop
  2. why not use nvvidconv convert color space in gpu ,but must use videoconvert
  3. I can use nvdec_h264 to decode video in gpu, but I can not find which is encode in gpu
