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

[guodecn]

citywolf,
I have not solve the problem, I have some advice for you.
First you can run my test example:
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

this example can work well on Marco Ballesio's machine. if you can work well
too, it show your pipeline has some problem, if not, show your machine
environment has some problem, but however, I think there is no problem to
virture machine(VMware workstation).

Good luck for you.
