* Include libavutil/channel_layout.h instead of libavutil/audioconvert.hJustin Ruggles2012-11-111-1/+1
| | | | Also reorder some other #include when applicable.
* mov: set channel layout for AC-3 streams based on the 'dac3' atom infoJustin Ruggles2012-02-221-1/+1
| | | | fixes Bug 225
* ac3enc: add channel coupling supportJustin Ruggles2011-05-241-0/+7
| | | | | | | | | Channel coupling is an optional AC-3 feature that increases quality by combining high frequency information from multiple channels into a single channel. The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies.
* Add apply_window_int16() to DSPContext with x86-optimized versions and use itJustin Ruggles2011-03-221-1/+1
| | | | in the ac3_fixed encoder.
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-191-4/+4

* Merge libavcore into libavutilReinhard Tartler2011-02-151-1/+1
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

* Move ff_ac3_critical_band_size_tab in ac3.c for non-hardcoded tables.Diego Elio Pettenò2011-01-251-5/+0
| | | | | | | 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>
* Add stereo rematrixing support to the AC-3 encoders.Justin Ruggles2011-01-081-0/+6
| | | | | | | | This improves the audio quality significantly for stereo source with both the fixed-point and floating-point AC-3 encoders. Update acodec-ac3_fixed and seek-ac3_rm test references. Originally committed as revision 26271 to svn://svn.ffmpeg.org/ffmpeg/trunk
* cosmetics: use some size macros in ac3tab.c/hJustin Ruggles2010-12-141-3/+3
| | | | Originally committed as revision 25969 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use the new libavcore audio channel API.Stefano Sabatini2010-11-211-8/+9
| | | | | | | This also allows to remove a linking dependency of libavfilter on libavcodec. Originally committed as revision 25789 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix grammar errors in documentationMåns Rullgård2010-06-301-2/+2
| | | | Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-201-1/+1
| | | | | | | | 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
* Update AC-3 channel map. 2F/2R layout only has 4 channels. This correctionJustin Ruggles2009-09-191-2/+2
| | | | | | does not change any current channel mapping behavior. Originally committed as revision 19919 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add channel layout support to the AC-3 decoder and AC-3 parser.Justin Ruggles2009-04-191-0/+15
| | | | Originally committed as revision 18622 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ac3dec: reorder output channels to SMPTE channel orderJustin Ruggles2009-04-171-6/+19
| | | | Originally committed as revision 18542 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ac3enc: reorder input channels to AC-3 channel orderJustin Ruggles2009-04-171-0/+15
| | | | Originally committed as revision 18540 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use full internal pathname in doxygen @file directives.Diego Biurrun2009-02-011-1/+1
| | | | | | | 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
* cosmetics: make all references to AC-3 capitalized and hyphenatedJustin Ruggles2008-08-031-3/+3
| | | | Originally committed as revision 14523 to svn://svn.ffmpeg.org/ffmpeg/trunk
* add a ff_ac3_parse_header_full() which calls ff_ac3_parse_header()Bartlomiej Wolowiec2008-04-241-0/+13
| | | | | | and then reads the channel_map stuff Originally committed as revision 12944 to svn://svn.ffmpeg.org/ffmpeg/trunk
