you need the latest verion from cvs, see bug #150449
get it send from vlc[1]
to play it right away:
gst-launch-0.8 -v udpsrc port=1234  ! ffdemux_mpegts ! ffdec_mpeg4 ! xvimagesink
to save to file first:
gst-launch-0.8 -v udpsrc port=1234  ! filesink location=/tmp/streamdump.ts
and play later:
gst-launch-0.8 -v filesrc location=/tmp/streamdump.ts ! ffdemux_mpegts !
ffdec_mpeg4 ! xvimagesink

switching on debuging in gst-ffmpeg/gst-libs/ext/ffmpeg/libavformat/mpegts.c
you get:

gst-launch-0.8 -v filesrc location=/tmp/streamdump.ts ! ffdemux_mpegts !
ffdec_mpeg4 ! xvimagesink
