Here faad is just getting mad, and throws a lot of:
[aac @ 0x85ce1f8]faac: frame decoding failed: Invalid number of channels

mplayer with lavf demuxer:
FAAD: Failed to decode frame: Invalid number of channels
FAAD: Failed to decode frame: Invalid number of channels
FAAD: Failed to decode frame: Invalid number of channels

sample tested was A-codecs/AAC/file.avi.
