UDP multicast from Wowza to hlssink

I believe there is missing flags for a raw mpeg-ts udp multicast stream not wrapped in RTP from Wowza. Ive tried looking elsewhere but failed. A simple playbin drops frames as is the other pipeline commands.

I may be looking into appsink to append the frames directly than generate hls. But there is no HLS output because of this dropping frame problem. publish and subscribe on the same machine for testing.

gst-launch-1.0 playbin3 uri=udp://224.0.0.0:4000 -v
