I have uninstalled everything and started again. Installing mpeg4ip
first, followed by ffmpeg, a52, faac, faad, lame, x264 and xvid.
I am not sure if this is the right place for this next question, but
hopefully you or
someone else may have encountered this next problem.
I have been able to extract a video track from and .mkv file, but
when I try to convert
the audio to aac using the following:
ffmpeg -i file.mkv -vn -acodec aac -ac 2 audio.aac
I get 'unknown encoder aac'
It seems to start alright with the following:
FFmpeg version UNKNOWN, Copyright (c) 2000-2008 Fabrice Bellard, et al.

followed by many lines of this:

and ends with:

Unknown encoder 'aac'
I am not sure if ffmpeg has its own encoder or if it should try to
use faac. Can anyone suggest how to
solve this one.
