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
