Thanks again. Finally I got it running

gst-launch-1.0 -e \
mpegtsmux alignment=7 name=mux ! \
rndbuffersize max=1316 min=1316 ! \
udpsink host=127.0.0.1 port=5000 sync=false \
decklinksrc mode=10 name=src \
src. ! audio/x-raw ! queue !  audioconvert ! \
voaacenc bitrate=128 ! aacparse ! mux. \
src. -v ! deinterlace ! videoconvert ! videorate ! videoconvert ! videoscale
! videoconvert ! video/x-raw, format=\(string\)I420, framerate=25/1,
width=720, height=400 ! aspectratiocrop aspect-ratio=16/9 ! queue !
videoconvert ! \
x264enc bitrate=1272 sync-lookahead=0 rc-lookahead=10 threads=0 ! h264parse
! mux.

Now I got 2 more questions:
Is it possible to send output to multiple ports using different quality
(bitrate) for each?
And then, what could I do to improve overall picture quality (now it looks
quite pixelated)
