It looks as if you're missing a codec.
FAAD is the native AAC decoder in Linux, so see if you have it

If you still can't figure it out, then you might have to extract the
audio from your Video File.
You can do this with FFMPEG with this simple command:

ffmpeg -i <input_file> -vn <output_file>

That will give you a complaint raw MPC audio file, from there you can
transcode it to whatever you like.

If you wish to encode it to MP4-AAC then on a terminal type:

faac -m4 -b64 -r48000 -pLC <input_file> <output_file>

Hope that helps.
