how to play mpeg-ts stream from rtp packet

[Soho Soho123]

Hi All,

Is it possible to play the mpeg-ts stream from UDP/RTP packet by
gstreamer pipeline?
I try the pipeline:
gst-launch-0.10 udpsrc port=28888
caps="application/x-rtp,clock-rate=90000" ! rtpmp2tdepay ! tsdemux !
decodebin2 ! audioconvert ! alsasink
it is fail, the error is not-linked from udpsrc.
As my understanding,
the source stream is :
h.264 encode for video
LPCM for Audio.
I just like to play audio data only,
Does anyone have idea?


Thanks!
