video network streaming with rtp problem

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:

put ffmpegcolorspace ! videoscale between the decoder and the video
sink.

Re: video network streaming with rtp problem

wim,
follow your advice, the rtp video transmit can work normal, but can you tell me why?
And how do you find the problem?
Thanks.
