H264 live pipeline problems on exynos odroid4 with hardware dec

[Ignas Brašiškis]

Hello I have problem with live pipeline.
Software pipeline works fine:
gst-launch-1.0 -v udpsrc port=10000 caps='application/x-rtp,
media=(string)video, clock-rate=(int)90000,
encoding-name=(string)H264' ! rtpjitterbuffer ! rtph264depay !
h264parse ! avdec_h264 !  videoconvert !  autovideosink
But hardware one, creates scrambled image:
gst-launch-1.0 -v udpsrc port=10000 caps='application/x-rtp,
media=(string)video, clock-rate=(int)90000,
encoding-name=(string)H264' ! rtpjitterbuffer ! rtph264depay !
h264parse ! v4l2h264dec !  videoconvert !  autovideosink


My source pipeline is simple:
gst-launch-1.0 -v v4l2src ! decodebin ! videoconvert ! x264enc
tune=zerolatency ! rtph264pay  ! udpsink host=192.168.1.195 port=10000
Zero latency tune does not change situation either way.
