[Libav-user] Error in opening a SDP file using libavcodec

[Hadi]

Hi, I tried to open a SDP file using the following code using libavcodec:

char *url = "foo.sdp";
AVFormatContext *oc = NULL;
avformat_open_input(&oc, url, NULL , NULL);

where the content of "foo.sdp" is as follows:

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 MP4V-ES/90000
a=fmtp:96 profile-level-id=1

but when I execute this code, I get the following error:

[udp @ 0049e6e0] bind failed: Error number -10048 occurred

Do you know what is the problem, and how I can solve it? Thanks!
