Diego Biurrun	b7f98659f2	Remove unnecessary get_bits.h #includes	9 years ago
Justin Ruggles	4c64c8e95a	ac3dec: fix processing of delta bit allocation information. The number of dba segments is the coded value + 1. The coupling dba offset starts at the first coupling band, not at zero.	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
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	4c57cde942	Add ff_ prefix to ac3_common_init(). Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	24e3ad3031	ac3: Remove ff_ac3_critical_band_size_tab. It is only used to generate band_start_tab, which about the same size, at runtime, so it's simpler just to always hardcode band_start_tab. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	6ed3b504f9	Move ff_ac3_critical_band_size_tab in ac3.c for non-hardcoded tables. This symbol is only ever used to calculate the non-hardcoded tables, so only enable it in that case, and static to the source unit that uses it. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	362bfe2997	Remove unused ac3_parametric_bit_allocation function. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	ce571ceb45	Use AC3_MAX_COEFS instead of 256 in a couple places in ac3.c Originally committed as revision 25968 to svn://svn.ffmpeg.org/ffmpeg/trunk	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
Måns Rullgård	49bd8e4b84	Fix grammar errors in documentation Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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
Reimar Döffinger	29b75f0b67	Change code so it uses 2 adds instead of one FFABS. About 1% faster ff_ac3_bit_alloc_calc_psd on Intel Atom, overall speedup not measurable though. Should have a bigger effect on systems without cmov or with very slow cmov. Originally committed as revision 21214 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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
