MEncoder does work using ffmpeg.

AAC isn't too much of a problem. MPEG-4 isn't either. FAAC/FAAD will  
take care of your AAC problems. Just install the libraries, and then  
compile MPlayer. MPEG-4 is a part of FFMPEG and LAVC, both of which  
MEncoder/MPlayer takes care of. The biggest problem is the QuickTime  
container. QuickTime is proprietary technology held by Apple, as far  
as I'm aware. If you have a Windows or a Mac OS X you could pay $30  
USD (might be $39 USD, not too sure) for QuickTime Pro, which will  
have all of those encoding options, as well as the ability to use the  
QuickTime container.

Good luck!
