Good morning,

I'm trying to live transcode input (mp2/mpeg2video) to
libamr_nb/ffh263(Supported formats in mobile devices), the problem is
that when launching
ffmpeg:

ffmpeg -i rtp://0.0.0.0?localport=2020 -acodec libamr_nb  -ar 8000 -ac 1 -ab
12.2k -f rtp rtp://192.168.50.147:8082 -an -vcodec h263p -flags aic -r 14 -b
20k -s 176*144 -f rtp rtp://192.168.50.147:8080

I have this very poor SDP:

v=0
o=- 0 0 IN IPV4 127.0.0.1
t=0 0
s=No Name
a=tool:libavformat
m=audio 8082 RTP/AVP 96
c=IN IP4 192.168.50.42
m=video 8080 RTP/AVP 96
c=IN IP4 192.168.50.42

and since 96 is a dynamic type, I have to add specifications to the
streaming server to make it able to deliver successful RTSP session (using:
a=rtpmap:96 H263-2000/90000 and a=rtpmap:96 AMR/8000/1).

I attached the SDP file I'm using. Realplayer is buffering until 100% but
not displaying video, and the audio is very fast as if the sampling
frequency is incorrect.

Help please!
