RTP from sdp: video disappear after some seconds, suggestions?

Hi all,

I'm having some trouble playing an rtp stream with description in a local sdp file. I see the video for some seconds and then it disappear, here is the launch command in verbose mode

gst-launch-0.10 -v filesrc location=test.sdp.2 ! decodebin ! autovideosink

I was looking at it as we speak, unfortunatly an SDP describing a
unicast stream does not seem to carry information about the destination
ports of the sender.. So I'm reading RFCs and trying to figure out what
to do.

Hi Win,

thanks for your answer, I try to explain better my situation:

- the sender is an encoder with ip 192.168.2.18
- the receiver is my laptop with ip 192.168.2.101

The sdp generated from the encoder is the following:

v=0
o=- 3451450218317 3451450218318 IN IP4 192.168.2.18
s=encoder_18.sdp
e=NONE
c=IN IP4 192.168.2.18
b=RR:0
t=0
m=video 5324 RTP/AVP 96
b=AS:5120
a=rtpmap:96 MP4V-ES/90000
a=fmtp:96 profile-level-id=3;config=000001B003000001B509000001010000012002045D4C28B42120A4C7

Using this sdp I'm able to see the video with vlc but not with gstreamer, the gstreamer error is:

bind failed -1: Impossibile assegnare l'indirizzo richiesto (99)

so I modified the sdp changing the line

c=IN IP4 192.168.2.18

c=IN IP4 192.168.2.101

this way I'm able to see the video but it disappear after few seconds (maybe the bug to which you refer)

regards
Nicola
