Different video size for streaming and recording

[Mazahir Poonawalla]

Hi Matt,

Thanks for the help, but this does not work.
My pipeline is as follows:

gst-launch -v -e 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 !
tee name=x ! queue ! rtph264pay ! udpsink port=3000 host=192.168.1.102
sync=false enable-last-buffer=false x. ! queue ! qtmux! filesink
location=test1.mp4 sync=false enable-last-buffer=false

So basically one thread is for streaming and other for recording on a file.
The default composite input video is 640*480. What if I want to record the
same size and stream at 320*240. Is it possible? I am running this on
Leopardboard DM365.

Thanks,
Maz
