I don't know what I could have done here but I'm running the command
which worked fine last night, but this morning now gives me the error "unknown encoder 'libfaac'
ffmpeg -i audio_orig -acodec libfaac -ab 128K -ac 2 audio.aac
I installed libfaac using the packages from Medibuntu as described on here http://ubuntuforums.org/showthread.php?t=1117283 using the commands
sudo wget http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list --output-document=/etc/apt/sources.list.d/medibuntu.list && sudo apt-get -q update && sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring && sudo apt-get -q update
does anybody know what could have changed or how I can get this working again??
sudo apt-get install ffmpeg libavcodec-extra-52
