  • Ticket #2809 – Description

    v13 v14  
    1 Summary of the bug: When converting files of any input format to AAC audio (in .mp4, .m4a, or .3gp 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.

    33How 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 ffmpeg command and -c:a aac and -strict -2 parameters) should produce the same results.
