[guodecn]

Hi,sudarshan bisht, Marco Ballesio,
Thanks for your reply.
Follow sudarshan bisht's advice, I have add the h264parse plugin between
h264depay and decodebin.
Follow Marco Ballesio's advice ,I have delete the udpsink's property
sync=false, and delete the redundant caps:ssrc clock-base and sequm-base.
As do above, the same error is still exist.

server:
gst-launch-0.10 -v videotestsrc ! x264enc ! rtph264pay ! udpsink
host=127.0.0.1 port=40000

client:
gst-launch-0.10 -v udpsrc
caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96"
port=40000 ! rtph264depay ! h264parse ! decodebin ! xvimagesink

attach is the error message.
