Video size - RTSP streaming

Hi,

I use the following plugin to do live RTSP streaming from Leopardboard to a
PC:

./TEST "( v4l2src always-copy=FALSE input-src=composite chain-ipipe=true !
video/x-raw-yuv,format=(fourcc)NV12, width=640, height=480 ! queue !
dmaiaccel ! dmaienc_h264 encodingpreset=2 ratecontrol=2
intraframeinterval=23 idrinterval=46 targetbitrate=3000000 ! rtph264pay
name=pay0 pt=96 )"

TEST contains the RTSP example source code. My input is a composite one
from external camera. My issue is that the change in video size i.e. width
and height in the above plugin has no effect on the output video size. I
tried changing the size in the above plugin to 720*480 & 720*576, but the
output video size always remains at 640*480. I checked the output stream
and its properties on PC using VLC.

Is the issue with the camera or leopardboard? How do I solve this problem.
Can you please provide some suggestions.

Thank you & Regards,

**
