 Summary of the bug: When converting files of any input format to AAC audio
 (in .mp4, .m4a, or .aac containers), the files will not play on Nintendo
 DSi/DSi XL/3DS/3DS XL. The files are detected, but when selected, they
 display "Could not play." It does not matter which AAC encoder is used.
 The fact that files encoded with libfaac in ffmpeg fail to play while the
 standalone faac works flawlessly suggests a problem in ffmpeg rather than
 the encoder.

 How to reproduce: Convert any file to AAC audio with frequency 41000-48000
 Hz and bitrate 16-320 kbps, copy to SD card, and attempt to play on a
 Nintendo handheld. One of the commands that I tried is listed below, but
 any variation (such as with avconv command and -c:a aac and -strict -2
 parameters) should produce the same results.

 {{{
 for f in *.webm; do ffmpeg -i "$f" -acodec libfaac -b:a 128k -ar 44100 -vn
 -af volume=1.50 "${f%.webm}.m4a"; done
