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
Mans Rullgard	6d9f52b2cd	ac3: move ff_ac3_bit_alloc_calc_bap to ac3dsp Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	b35743ffb4	ac3: define AC3_MAX_CPL_BANDS and use it in ac3dec.h	14 years ago
Justin Ruggles	c73d99e672	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>	14 years ago
Justin Ruggles	9d06d7bce3	Remove the add bias hack for the C version of DSPContext.float_to_int16_*().	14 years ago
Justin Ruggles	47ae6e795b	define AC3_CRITICAL_BANDS and use it in the AC-3 encoder and decoder. Originally committed as revision 25967 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	7066cc8f2b	cosmetics: use better (and shared) macro names for some constant values Originally committed as revision 25950 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	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	1429224b04	Move FFT parts from dsputil.h to fft.h Originally committed as revision 22235 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
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Justin Ruggles	bb5b99a789	cosmetics: move fixed_coeffs into the aligned arrays comment group Originally committed as revision 19590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 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

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	e202cc2580	revert r15812 (E-AC-3 Spectral Extension) pending further review Originally committed as revision 15818 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. 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	16 years ago
