Raspberry pi hardware accelerated playback

Hi. I've been trying to play either a udp h264 stream or a video file with
hardware acceleration.

With this command I get VERY choppy playback, low cpu usage and a lot of
banding:

gst-launch-1.0 -qe udpsrc port=5002 do-timestamp=true ! queue !
application/x-rtp, payload=96 ! rtpjitterbuffer latency=10 ! rtph264depay !
h264parse ! omxh264dec ! glimagesink

adding

enable-last-sample=false qos=false

to the glimagesink makes it somewhat better, but still horrible.

Similar thing (banding, low fps, low cpu usage) happens with:
gst-launch-1.0 filesrc location=file.mp4 ! qtdemux ! h264parse ! omxh264dec
! glimagesink

I compiled this version on my own, I'm running 1.11.1 right now.

What can I do about this?
