I saw the message at: 

This is to confirm that I'm having the same problem with ffmpeg CVS snapshot 
as of 21 December. I'm trying to encode video with an average bitrate of 
192kbps and audio 48kbps and getting a total average bitrate of around 
550kbps. The command I'm using is:

ffmpeg -b 192 -ab 48 -bufsize 256 -i "$1" -vcodec h264 -acodec aac -s 360x288 
-cropleft 20 -cropright 20 -cropbottom 16 -croptop 16 -ac 1 -ar 22050 

I've submitted a bug report which contains a little more detail, along with 
complete ffmpeg output at: 

I really need bitrate control right now, since I'm trying to use ffmpeg to 
generate videos for streaming, so it would be very useful to me if this were 
fixed soon!
