Comment (by Kamedo2):

 The assertion error of v9b patch when the {{{aac_coder}}} is set to
 {{{anmr}}}, {{{ffmpeg.exe -y -i audio_file -c:a aac -strict experimental
 -aac_coder anmr -b:a xxk out.mp4}}}
 {{{
 Assertion diff >= 0 && diff <= 120 failed at libavcodec/aacenc.c:399
 }}}
 was investigated again by looking into full behavior of {{{static void
 encode_scale_factors()}}}.
 I don't know why, but the numerical value is slightly different from the
 comment:356.

 {{{sce->sf_idx[w*16 + i]}}} spikes when the assertion error happens.
