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	3da1180409	Move some prototypes from dsputil.c to reasonable header files Originally committed as revision 22260 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
Måns Rullgård	01b2214758	Merge FFTContext and MDCTContext Originally committed as revision 19931 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
Justin Ruggles	0cc51734b2	add support for spectral extension Originally committed as revision 15812 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	17 years ago
Justin Ruggles	260e09305b	remove unneeded variable, dither_all Originally committed as revision 15011 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
