Need help to display a video stream with Gstreamer

[Marianna Smidth Buschle]

Your video is in a MPEGTS container, so you need to fix the CAPS and 
depayloader.

Try something like:

gst-launch-1.0 udpsrc port=3001 auto-multicast=true multicast-group="224.100.10.10" !|application/x-rtp,media=video,payload=33,clock-rate=90000,encoding-name=MP2T 
! rtpbin ! rtpmp2tdepay|  ! decodebin ! videoconvert ! autovideosink

Best Regards
Marianna
