2014-02-28dcadec: remove scaling in lfe_interpolation_firChristophe Gisquet
The scaling factor is constant so it is faster to scale the FIR coefficients in the tables during compilation. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

2013-11-29dca: support mixing LFE in dca_downmix.Tim Walker
Embedded downmix coefficients can use this. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2013-11-29dca: improve default stereo downmix coefficients.Tim Walker
Previous coefficients were producing a non-normalized, incorrect Lt/Rt downmix. The new coefficients produce a standard Lo/Ro downmix with 3dB attenuation. This should match the typical default coefficients used by DTS encoders. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2013-11-29dca: extract core substream's embedded downmix coeffcient codes, if present.Tim Walker
As per ETSI TS 102 114 V1.4.1 specification. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2013-11-29dca: remove embedded downmix coefficient extraction.Tim Walker
It was based on an old, seemingly incorrect specification, so default coefficients were always used anyway. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2013-11-29dca: convert dca_default_coeffs to float.Tim Walker
Easier to read, modify, and avoids relying on an outdated table. Signed-off-by: Anton Khirnov <anton@khirnov.net>

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-13DCA: 16-byte-align lfe_fir tablesMåns Rullgård
Originally committed as revision 22862 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-12DCA: simplify lfe_interpolation_fir()Måns Rullgård
This reorders the lfe_fir tables, and drops the mirrored half, such that the loops in lfe_interpolation_fir() can be simplified. The new loop structure should be easier to implement with SIMD. Static data size is reduced by 2kB. 3% faster on Cortex-A8. Originally committed as revision 22849 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun

2008-08-31Globally rename the header inclusion guard names.Stefano Sabatini
Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
