2011-02-15aacdec: Implement LTP support.Young Han Lee
Ported from gsoc svn. (cherry picked from commit ead15f1dc196ad164d105e31c8c9025f8a4ee4e7)
2011-02-04Separate format conversion DSP functions from DSPContext.Justin Ruggles
This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit c73d99e672329c8f2df290736ffc474c360ac4ae)
2011-01-28Remove the add bias hack for the C version of DSPContext.float_to_int16_*().Justin Ruggles
(cherry picked from commit 9d06d7bce3babb82ed650c13ed13a57f6f626a71)
2010-09-10aacdec: Rework channel mapping compatibility hacks.Alex Converse
For a PCE based configuration map the channels solely based on tags. For an indexed configuration map the channels solely based on position. This works with all known exotic samples including al17, elem_id0, bad_concat, and lfe_is_sce. Originally committed as revision 25098 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-05Whitespace cosmeticsAlex Converse

2010-06-03aacdec: Work around illegal files with all elem_id tags set to the same value.Alex Converse
Fixes issue 1882. Originally committed as revision 23439 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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
2010-03-08Add an HE-AAC v1 decoder.Alex Converse
A large portion of this code was orignally authored by Robert Swain. The rest was written by me. Full history is available at: svn://svn.ffmpeg.org/soc/aac-sbr http://github.com/aconverse/ffmpeg-heaac/tree/sbr_pub Originally committed as revision 22316 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Move FFT parts from dsputil.h to fft.hMåns Rullgård
Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård
These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-22Move array specifiers outside DECLARE_ALIGNED() invocationsMåns Rullgård
Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-13AAC: Reduce depth of vlc_spectral tables to 2Måns Rullgård
Up to 6% faster overall on i7, no change on A8. Originally committed as revision 21191 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-12-02AAC: Add a global header but output not locked output configuration status.Alex Converse
Originally committed as revision 20701 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-04Don't lock the channel output configuration based on the first value seen forAlex Converse
non extradata formats. Instead lock it only after the successful decoding of a frame. This fixes issue 999. Originally committed as revision 20448 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-20Merge FFTContext and MDCTContextMåns Rullgård
Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-11Ignore subsequent channel configurations after the first in an AAC file. TheAlex Converse
current code doesn't handle them properly, and they are a dubious construction at best. Originally committed as revision 19399 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-09Merge the AAC encoder from SoC svn. It is still considered experimental.Alex Converse
Originally committed as revision 19375 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 16939 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun

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
2008-08-22Use ff_imdct_half() and vector_fmul_window() for IMDCT and windowing. ReduceRobert Swain
