Hello,

I'm trying to feed snowmix (http://sourceforge.net/projects/snowmix/) with
multicast source. Currently I have the following pipeline (not working of
course): 

gst-launch-1.0 -q udpsrc multicast-group='224.0.0.5' auto-multicast=true
port=1234 ! ... ! video/x-raw, format=BGRA, pixel-aspect-ratio=1/1,
interlace-mode=progressive, width=1024, height=576, framerate=24/1 ! shmsink
socket-path=/tmp/feed-control-pipe-3-4 shm-size=40000000
wait-for-connection=0

UDP source is a h264 video and i can't seem to find a way to decode it
properly. Everything seems to fail. Below is the pipeline for feeding
snowmix from file (working):

gst-launch-1.0 -q filesrc location=/tmp/video1.mp4 ! decodebin name=decoder
! \
            videorate ! videoscale ! \
            videoconvert ! \
            video/x-raw, format=BGRA, pixel-aspect-ratio=1/1,
interlace-mode=progressive, width=1024, height=576, framerate=24/1 ! \
            shmsink socket-path=/tmp/feed-control-pipe-3-4 shm-size=40000000
wait-for-connection=0

If someone could help me out here, that'd be great!

Thank you.
