[gst-devel] rtp transmit occur "not-negotiated (-4)" error

[guodecn]

Hi,Marco Ballesio,
Thanks for your reply very much.

>>However, the issue was the place you've set the "port" property.
what's your mean? Don't udpsrc need the port property? if don't udpsrc have
no port property, we can't receive the data.

I have modify the pipeline as below:

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

client:
gst-launch-0.10 -v udpsrc port=40000 caps=
"application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96"
! rtph264depay ! ffdec_h264 ! xvimagesink


But the same error is still exist. Can you modify my pipeline correct, and
show me.

Thanks.
