Comment (by alexander at linuxfromscratch.org):

 faac and faad2 are indeed useful, and libfaac is even required for
 creating iPod-playable mp4 video files (because iPod doesn't understand
 other audio codecs in video files). However, I prefer to use ffmpeg for

 ffmpeg -i capture.avi -acodec libfaac -ab 128kb -s 320x240 -vcodec libx264
 -flags +mv4+obmc+qpel+trell -me_method full -g 250 -qmin 25 -qmax 25
 -level 13 -title 'Capture' capture.mp4

 which prompts me whether we should also add x264 to the book.

 Watch, however, for licensing problems:

 ** Software using this code must display the following message visibly in
 ** software:
 ** "FAAD2 AAC/HE-AAC/HE-AACv2/DRM decoder © Ahead Software, www.nero.com"
 ** in, for example, the about-box or help/startup screen.

 That's why xine and mplayer developers maintain their private copy of
 faad2, and it receives more fixes than the original.

 Ubuntu fixed the license problem by using the last CVS snapshot without
 the offenfing "nero" bit, plus fixes.

 Also the following bit from Debian changelog is interesting:

  * Compile without Digital Radio Mondiale support, as it breaks base

 IMHO, this breakage should be mentioned.
