[gst-devel] video network streaming with rtp problem

[citywolf]

hi,all
here are my commands:

#server:
gst-launch -v videotestsrc !  ffenc_mpeg4  ! rtpmp4vpay send-config=true !
udpsink host=218.192.168.112 port=5000


#client:
gst-launch -v  udpsrc port=5000 caps=" application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP4V-ES,
profile-level-id=(string)1,config=(string)000001b001000001b58913000001000000012000c48d8800f50a041e1463000001b24c61766331642e35312e33382e30,
payload=(int)96,ssrc=(guint)3127939974, clock-base=(guint)3486206175,
seqnum-base=(guint)28199" ! rtpmp4vdepay  ! ffdec_mpeg4 !  ximagesink


it causes the following problem:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

can anyone help me?
