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	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	15 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	15 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
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	30f68128ab	Add missing #includes to fix 'make checkheaders'. Originally committed as revision 17398 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	16 years ago
Justin Ruggles	260e09305b	remove unneeded variable, dither_all Originally committed as revision 15011 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Justin Ruggles	0ffea2439b	copy default coupling band structure from table to decoding context (used for E-AC-3) Originally committed as revision 14990 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	c5b930e674	1000l to me. committed to wrong repo. revert last commit. Originally committed as revision 14953 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
