mplayer2 wont decode audio

[Mike Jakubik]

Hello,

I just installed mplayer2 on a new machine and i'm having trouble 
getting it to decode audio, mplayer gives the following warning:

Selected video codec: H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [libavcodec]
The player has been compiled without libavresample support,
which is needed with this libavcodec decoder version.

Audio decoder init failed for codecs.conf entry "ffaac".
Requested audio codec family [faad] (afm=faad) not available.
Enable it at compilation.

However i don't see any options for these in either mplayer2 or ffmpeg1.

Thanks.
