[Ffmpeg-user] audio codec for mp4a, 8000 Hz, stereo

[andrew at flypublishing.com]

Thanks, I got faad2-2.0.tar.gz, compiled it, installed it then
re-compiled ffmpeg with --enable-faad.  I was getting ffmpeg: error
while loading shared libraries: libfaad.so.0 after that but then did
export LD_LIBRARY_PATH=/usr/local/lib and that error went away.

But I still get "Unsupported codec (id=0) for input stream #0.1"

Here's the output:

$ ffmpeg -i test.3gp -acodec mp3 -ar 22050 -ab 32 -y test.mpg
