Just swap the kmssink at the end of the pipeline with a xvimagesink and
be done with it. The only complication is that the armada driver
exposes 2 XV adapters, one going to a KMS plane (not really functional
on i.MX6) and one using the GPU accel path. You need to choose the
right one by either configuring the right default in the xorg.conf or
using the device parameter for the xvimagesink.
