CPU load won't be constant with avdec software decoding. If you need to
smooth this a little, I would recommend to use the HW decoder (device
number may differ depending on your kernel, some cherry pick of upstream
kernel fix might be needed, even though Hardkernel should have most of
these already, gstreamer 1.4 is needed):

gst-launch-1.0 filesrc location=$file ! qtdemux ! h264parse ! queue ! v4l2video8dec ! v4l2video10convert ! queue ! fakesink sync=true

cheers,
