udpsrc -> decode -> shmsink

[buzzy]

Hello, Peter,

yes, thank you. I was just constructed this pipeline on friday. I've added
the sound also:

(
    echo "audio feed ctr isaudio $AUDIO_FEED_ID";\
    gst-launch-1.0 -q udpsrc multicast-group=$MULTICAST_ADDRESS
auto-multicast=true port=1234 ! decodebin name=decoder ! videorate !
videoscale ! videoconvert ! \
    video/x-raw, format=BGRA, framerate=24/1, width=$WIDTH, height=$HEIGHT
! videoconvert ! \
    shmsink socket-path=$FEED_PIPE shm-size=40000000 wait-for-connection=0
decoder.   ! queue ! audioconvert ! audioresample ! \
    audio/x-raw, format=S16LE, rate=48000, channels=2 ! fdsink fd=1
sync=true \
) | nc $IP $PORT

But still there's one problem. I need this input to be valid for 3
different resolutions: 1280x720, 1024x576, 768x432. The last two works well
(I'm changing WIDTH and HEIGHT values in script), but it doesn't work with
1280x720 resolution. It starts to work and then fails after couple of
seconds. Is there are way to make this work? Is it a resize problem?

Thank you.
