* ac3dec: fix processing of delta bit allocation information.Justin Ruggles2011-04-17
| | | | | The number of dba segments is the coded value + 1. The coupling dba offset starts at the first coupling band, not at zero.
* ac3: move ff_ac3_bit_alloc_calc_bap to ac3dspMans Rullgard2011-03-29
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Add ff_ prefix to ac3_common_init().Justin Ruggles2011-01-26
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* ac3: Remove ff_ac3_critical_band_size_tab.Justin Ruggles2011-01-26
| | | | | | | 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>
* Move ff_ac3_critical_band_size_tab in ac3.c for non-hardcoded tables.Diego Elio Pettenò2011-01-25
| | | | | | | 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>
* Remove unused ac3_parametric_bit_allocation function.Diego Elio Pettenò2011-01-25
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Use AC3_MAX_COEFS instead of 256 in a couple places in ac3.cJustin Ruggles2010-12-14

* Fix grammar errors in documentationMåns Rullgård2010-06-30
| | | | Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | 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
* Change code so it uses 2 adds instead of one FFABS.Reimar Döffinger2010-01-14
| | | | | | | | 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
