[FFmpeg-user] Fedora Unkown encoder 'libmp3lame'

[scoliver]

Thanks James.
I downloaded ffmpeg from websites  http://ffmpeg.org/releases/
http://ffmpeg.org/releases/  instead of SVN. I use the latest version 0.8.5.
Today I find ffmpeg installed /usr/local ,but the encodecs were installed
/usr .So I install ffmpeg again .

./configure --prefix=/usr  .....
Then it works out !  I am  very glad! Ffmpeg can use these encoder like
libmp3lame,libxvid,libfaac. But it still shows "Unknown encoder
'libopencore-amrwb'" .  (cmd: ffmpeg -i test.avi -y -b 20 -s sqcif -r 10
-acodec libopencore-amrwb -ab 23.85 -ac 1 -ar 16000 test.3gp)

./configure --help   shows:
--enable-libopencore-amrnb     enable AMR-NB de/encoding via
libopencore-amrnb [no]
--enable-libopencore-amrwb     enable AMR-WB decoding via libopencore-amrwb
[no]
--enable-libvo-amrwbenc          enable AMR-WB encoding via libvo-amrwbenc
[no]
I use opencore-amr -0.1.2. 

>From the internet ,there are amrnb-7.0.0.2 and amrwb-7.0.0.4. But  from
version 0.6 on ,ffmpeg use libopencore-amrnb.
ffmpeg-0.5      ./configure --help 
--enable-libamr-nb        enable libamr-nb floating point audio codec [no]
--enable-libamr-wb       enable libamr-wb floating point audio codec [no]

I try to install ffmpeg-0.5,using amrnb-7.0.0.2 and  amrwb-7.0.0.4. But it
shows "Unknown encoder 'libamr-wb'" .(cmd: ffmpeg -i test.avi -y -b 20 -s
sqcif -r 10 -acodec libamr-wb -ab 23.85 -ac 1 -ar 16000 test.3gp)
I am very disappointed these days becausing of installing ffmpeg and testing
it !   

Can you give me some suggestion ? 

Thanks.
