[FFmpeg-devel] [PATCH] HE-AAC v1 decoder

[Alex Converse]

Greetings Sirs,

Enclosed you will find one (1) HE-AAC decoder to make glorious great
software FFmpeg.

Heart,

Alex

=================

More seriously, attached is a patch that implements SBR and integrates
it with AAC to make an HE-AAC v1 decoder. A filterbank compatible with
ff_float_to_int16_interleave_c is missing but otherwise the code is
complete. Note that the decoder spends 90+% of its time in the
filterbank and will be extremely slow on any system that does not have
a asm version of  scalarproduct_float().
