Haven't dealt with your input codec before but:

[C David Young] "Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height"

you need to set these parameters...

here are some examples:
bitrate: -ab 128k
rate: -ar 48k
channels: -ac 2

Also, by specifying aac as the encoder, you are using the experimental aac encoder. I would recommend installing libfaac and recompiling FFmpeg with --enable-libfaac. The you would specify -acodec libfaac.
