I tried with this sdp :

v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
c=IN IP4 127.0.0.1
t=0 0
a=tool:libavformat 55.22.100
m=video 1234 RTP/AVP 96
b=AS:200
a=rtpmap:96 VP8/90000
a=fmtp:96 apt=100

with no luck. the stream is outputted at rtp://127.0.0.1:5000 do i need the
port to the sdp ?

Thanks Carl for your comment.

William.
