834550ea 12/16/2010 09:09 PM Justin Ruggles

Speed up group minimum and group output calculations for EXP_D25 and EXP_D45
in encode_exponents_blk_ch() by removing the inner loops. This is about 30-40%
faster for the modified sections.

Originally committed as revision 26036 to svn://svn.ffmpeg.org/ffmpeg/trunk

cdedf7e6 12/16/2010 09:09 PM Justin Ruggles

Convert a for() loop into a while() loop for the downward part of the exponent
delta limiting.

Originally committed as revision 26035 to svn://svn.ffmpeg.org/ffmpeg/trunk

27af78cf 12/16/2010 09:09 PM Justin Ruggles

Redesign encode_exponents_blk_ch() so that duplicate exponent sets are no
longer required. This gets rid of the temp buffer as well as encoded_exp in
AC3EncodeContext. It also allows for skipping the exponent grouping for
EXP_D15. 56% faster in encode_exponents_blk_ch()....

8846ee54 12/16/2010 03:06 PM Justin Ruggles

Use optimized function DSPContext.sad0() instead of calc_exp_diff().
90% faster compute_exp_strategy().

Originally committed as revision 26033 to svn://svn.ffmpeg.org/ffmpeg/trunk

configure: Avoid warnings if av_always_inline is disabled

This macro is disabled if --enable-small or --disable-optimizations are set.
Currently, this leads to warnings about functions being defined but not used,
for functions in header files.

By defining av_always_inline as inline or as av_unused, we avoid these...

cosmetics: pretty-printing after last commit

Originally committed as revision 26031 to svn://svn.ffmpeg.org/ffmpeg/trunk

89bedc4d 12/16/2010 03:44 AM Justin Ruggles

Add a goto for init failure instead of duplicate calls to ac3_encode_close().

Originally committed as revision 26030 to svn://svn.ffmpeg.org/ffmpeg/trunk

c41ac4f8 12/16/2010 03:44 AM Justin Ruggles

Use pre-allocated temp buffers in mdct512().
5% faster in function.

Originally committed as revision 26029 to svn://svn.ffmpeg.org/ffmpeg/trunk

e29065f7 12/16/2010 03:13 AM Justin Ruggles

Write results of post-rotation complex multiply directly to output.
2% faster in function mdct512().

Originally committed as revision 26028 to svn://svn.ffmpeg.org/ffmpeg/trunk

9d853336 12/16/2010 03:13 AM Justin Ruggles

Use memcpy() instead of a for loop in mdct512().
8% faster in function.

Originally committed as revision 26027 to svn://svn.ffmpeg.org/ffmpeg/trunk
