One possible cause for the low performance of videoconvert might be the missing ORC support for AArch64 (https://gstreamer.freedesktop.org/projects/orc.html).

The issue appears to be specific to GStreamer 1.10.2. It could not be reproduced with 1.8.0
Therefore it is considered not relevant to this project.
Example videoconvert with GStreamer 1.8.0
gst-launch-1.0 v4l2src io-mode=3 ! 'video/x-raw, width=3840, height=2160, framerate=30/1, format=UYVY' ! videoconvert ! 'video/x-raw, format=I420' ! xvimagesink
