2009-09-20Merge FFTContext and MDCTContextMåns Rullgård
Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-08-05cosmetics: move fixed_coeffs into the aligned arrays comment groupJustin Ruggles
Originally committed as revision 19590 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-08-05Modify decode_band_structure() so that the actual band structure is onlyJustin Ruggles
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
2009-08-05Use coupling band sizes instead of coupling band structure whenJustin Ruggles
calculating coupling transform coefficients. Originally committed as revision 19584 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-06-12The internal header libavutil/internal.h should not be used outside libavutil.Diego Biurrun
Originally committed as revision 19157 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-05-06ac3dec: Remove unneeded context variable, num_cpl_subbands. It is alsoJustin Ruggles
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
2009-04-19Add channel layout support to the AC-3 decoder and AC-3 parser.Justin Ruggles
Originally committed as revision 18622 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-13Rename bitstream.h to get_bits.h.Stefano Sabatini
Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-02-18Add missing #includes to fix 'make checkheaders'.Diego Biurrun
Originally committed as revision 17398 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun
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
2008-11-14revert r15812 (E-AC-3 Spectral Extension) pending further reviewJustin Ruggles
Originally committed as revision 15818 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 15812 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-08-31Globally rename the header inclusion guard names.Stefano Sabatini
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
