Question on pipeline

In an effort to take a wmv file as source and change it to ogg and
multicast it - I did the following:

I took the test-multicast.c file... I changed the line
for gst_rtsp_media_factory_set_launch () to be passed from command line.
gst_rtsp_media_factory_set_launch (factory, argv[1]);

then I wrote a small script:
----
MULTICAST_ADDRESS="239.168.3.10"
PORT="5000"

WMV_PIPE=""
WMV_PIPE="$WMV_PIPE ( filesrc
location=/home/silentm/trailer_videos/Amazon_1080.wmv "
WMV_PIPE="$WMV_PIPE ! fluasfdemux name=d ! queue ! fluwmvdec !
ffmpegcolorspace ! queue ! theoraenc "
WMV_PIPE="$WMV_PIPE ! rtptheorapay ! udpsink host=$MULTICAST_ADDRESS
port=$PORT d. ! queue ! fluwmadec ! audioconvert ! queue ! vorbisenc !
rtpvorbispay "
WMV_PIPE="$WMV_PIPE ! udpsink auto-multicast=true host=$MULTICAST_ADDRESS
port=$PORT )"

test-multicast  "$WMV_PIPE"



This didn't seem to work. doing "tshark -x ip multicast" was not showing
anything.

What might I be missing?
