Michael Niedermayer	8bce5c8e74	avcodec/ac3dec: Use avpriv_float_dsp_alloc() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Jean-Francois Thibert	12df9b9a15	Improved AC3 decoder level support (heavy drc, dialnorm) Added support for AC3 heavy dynamic range compression used to restrict the output range and added a setting to specify the output target level and use the dialog normalization field to apply it in the digital domain. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	b219142921	avcodec/ac3: rename identifier used to select the fixed point variant the CONFIG_ prefix is used by configure, using it for other things is potentially confusing to the reader Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Nedeljko Babic <nbabic@mips.com>	11 years ago

Christophe Gisquet	f49564c607	fmtconvert: int32_t input to int32_to_float_fmul_scalar It was previously declared as int. Does not change fate results for x86. Conflicts: libavcodec/ppc/fmtconvert_altivec.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Reimar Döffinger	459fe331e9	ac3dec: avoid pointless alloc and indirection for input_buffer Since we now always allocate it, it can simply be made part of the context instead.	13 years ago

Anton Khirnov	9b83919f44	ac3dec: add a drc_scale private option Deprecate corresponding AVCodecContext option. This is the first test of decoder private options.	14 years ago
Reinhard Tartler	21a19b7912	doxygen: Prefer member groups over grouping into modules Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.	14 years ago
Reimar Döffinger	86961eeabf	ac3dec: fix doxy-style for comment ("///>" should be "///<" instead). Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Justin Ruggles	7f3a7b5c40	ac3enc: add channel coupling support Channel coupling is an optional AC-3 feature that increases quality by combining high frequency information from multiple channels into a single channel. The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies.	14 years ago
Vitor Sessak	9d35fa520e	Add AVX FFT implementation. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago

Justin Ruggles	be18738801	Get audio_service_type for AC-3 based on bitstream mode in the AC-3 parser and decoder, and vice-versa for the AC-3 encoder.	14 years ago

Justin Ruggles	fe2ff6d247	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `c73d99e672`)	14 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands.

Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	ca6e7708b4	Add spectral extension to the E-AC-3 decoder. Original patch by Justin, updated and resubmitted by Christophe Gisquet, christophe D gisquet A gmail Originally committed as revision 22734 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Justin Ruggles	3f93716809	Modify decode_band_structure() so that the actual band structure is only used within the function. This removes the need to have the coupling band structure stored in the AC3DecodeContext. Originally committed as revision 19585 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	603139022d	Use coupling band sizes instead of coupling band structure when calculating coupling transform coefficients. Originally committed as revision 19584 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	477ffff218	The internal header libavutil/internal.h should not be used outside libavutil. Originally committed as revision 19157 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	396b73c7f7	ac3dec: Remove unneeded context variable, num_cpl_subbands. It is also not needed for spectral extension or enhanced coupling since it is redundant information, so I am removing it from decode_band_structure() as well. Originally committed as revision 18751 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	bfeca7beb6	Add channel layout support to the AC-3 decoder and AC-3 parser. Originally committed as revision 18622 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
