Problem with video encoding on beagleboardxm

Hi friends

my name is bharath. I am now working on Robotic project. I am actually need to encode and stream video through wlan. the problem I am facing is I am getting a delay of 3sec at client side. I used the gstreamer0.10 . the problem still persisted to 1.5 sec. Can any body suggest me to get a delay of less than 0.5 ms

thanks in advance
