Hi everyone. I've been using gstreamer for android to streaming video from
raspi, this is my sending pipeline: 

gst-launch-1.0 -v v4l2src ! video/x-raw ! omxh264enc ! rtph264pay
config-interval=1 pt=96 ! gdppay ! tcpserversink host=0.0.0.0 port=5002

The streaming reception is perfect in my Galaxy S3 and even in a low
performance  smartphone, XperiaU. using this command:

tcpclientsrc host=10.5.5.142 port 5002 ! gdpay ! rtph264depay ! avdec_h264 !
videoconvert ! autovideosink sync=false

However when I run the same app in my "Omimo 3D Android Video Glasses" with
a 
CPU: Allwinner H8 Octa-Core Cortex-A7CPU and a 
GPU: Mali400MP2 PowerVR SGX544GPU 

The streaming shows a video lag of about 10 seconds. Any idea? thanks.
