rkximagesink

[James]

I'm trying to use hardware decoding and i'm confused. If anyone can point a way forward then thanks.
(simplifed pipeline but the error is clear)

This pipeline works

gst-launch-1.0 -v -m videotestsrc ! rkximagesink

This pipeline works on xvimagesink

gst-launch-1.0 -v v4l2src device=/dev/video1 ! image/jpeg,framerate=30/1 \
	! jpegdec ! \
        videoconvert ! \
	queue ! \
	gdkpixbufoverlay location=rennisons.png alpha=0.5 offset-x=1800 offset-y=900 ! \
	clockoverlay halignment=left valignment=top draw-outline=true font-desc="Sans, 12" time-format="%d %b %Y %H:%M:%S" ! \
	textoverlay text="This is Line 1" deltay=50  halignment=left valignment=top font-desc="Sans, 10" ! \
	queue ! rkximagesink sync=false

but with rksimagesink
