2010-07-24aacenc: TLS: Save maximum values for each swb in a table.Alex Converse
This gives an almost 20% speedup. Originally committed as revision 24484 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-2410l: Remove some commented out code that slipped in.Alex Converse
Originally committed as revision 24483 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-24aacenc: TLS: Try to preserve some energy in each non-zero band.Alex Converse
Reduce scalefactors in non-zero bands that underflow by twice as much as those in bands that just fail to hit psy targets. Originally committed as revision 24482 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-24aacenc: Prevent premature termination of the two loop search.Alex Converse
Originally committed as revision 24476 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 24473 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-24aacenc: Factorize some scalefactor utilities.Alex Converse
Originally committed as revision 24472 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-20aacenc: Convert if () abort() to assert().Alex Converse
Originally committed as revision 24336 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 24273 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-29aacenc: Fill in the estimated codebook for the final computed scalefactor in ↵Alex Converse
the TLS. Originally committed as revision 23869 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-29aacenc: Remove an unnecessary division from the TLS.Alex Converse
Originally committed as revision 23368 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-29Cosmetics: whitespaceAlex Converse
Originally committed as revision 23367 to svn://svn.ffmpeg.org/ffmpeg/trunk

searches. Originally committed as revision 23322 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 23319 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-25aacenc: Trellis over scalefactors using an estimated codebook rather than ↵Alex Converse
every codebook. The minimal codebook to encode the band without clipping is used (as is done in the TLS). Originally committed as revision 23318 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-25aacenc: Only trellis over a column of 61 scalefactors (reduced from 256).Alex Converse
This still provides plenty of dynamic range, makes every move legal, and greatly reduces the search space. Originally committed as revision 23317 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-25aacenc: Factor out find_min_book so it can be used by multiple coefficient ↵Alex Converse
coders. Originally committed as revision 23316 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 23136 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-14aacenc: Use exact values when quantizing, not fuzzy values.Alex Converse
This requires us to code small escapes; we can't avoid it. Originally committed as revision 23135 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-14aacenc: Use an estimated codebook for the TLS (two loop search).Alex Converse
Originally committed as revision 23134 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 23037 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-05-07Make the faac inspired quantizer search make sense for a slightly narrower ↵Alex Converse
definition of "make sense." Originally committed as revision 23035 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun

2010-03-24aacenc: Merge quantize_band_cost() with quantize_and_encode_band().Alex Converse
If these two functions aren't matched results may be unexpected. Originally committed as revision 22655 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-21aacenc: Use preprocessor constants for trellis states and stages.Alex Converse
Originally committed as revision 19948 to svn://svn.ffmpeg.org/ffmpeg/trunk
