This is the error message I got
[libmp3lame @ 0x95c0090]lame: output buffer too small (buffer index: 9404, free bytes: 388)
Audio encoding failed

Error caused by incompatible libmp3lame 3.98-2 with ffmpeg
I've googled this error message and found out sometimes it attaches this note "can be treated with downgrade libmp3lame to version 3.97 or 3.98"

Thing is, in most updated distros' repositories, you will not find these 'outdated' versions.
I've done it on CentOS 5.4, it should not be too far away from this explination in any other distro.

1. we remove version 3.98.2
rpm -e --nodeps lame  
rpm -e --nodeps lame-devel  

Open in new window


2. download the required version of libmp3lame
wget http://downloads.sourceforge.net/lame/lame-398.tar.gz   

Open in new window


3. Extract:
tar xvvzf lame-398.tar.gz

Open in new window


4. Go into the extracted directory
cd lame-398

Open in new window


5. and build!
./configure  
make  
make install  

Open in new window


We're almost done now, but if you'll try you'll get the following error message
ffmpeg: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory

Open in new window


let's fix up the proper links for the new library;
for 32bit OS:
cd /usr/local/lib
ln -s /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib/libmp3lame.so.0

Open in new window


and for 64bit OS:
cd /usr/local/lib
ln -s /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib64/libmp3lame.so.0

Open in new window


And voila!
