* lavc: remove unused traces of fmtconvert usageAnton Khirnov2015-02-28
| | | | | Those decoders have been switched to float output and so do not use fmtconvert anymore.
* aacdec: Support for ER AAC ELD 480.Alex Converse2015-02-03
| | | | Based in part on work from Niel van der Westhuizen <espes@pequalsnp.com>.
* aac: Add support for Enhanced AAC Low Delay (ER AAC ELD).Alex Converse2013-10-23
| | | | | This does not include support for LD SBR, epTool, data resilience, nor the 960 transform family.
* aacdec: Add support for LD (Low Delay) AACAlex Converse2013-09-18

* miscellaneous typo fixesDiego Biurrun2013-07-25

* Remove unnecessary dsputil.h #includesDiego Biurrun2013-02-26
|
* aac: decode directly to the user-provided AVFrameJustin Ruggles2013-02-12
|
* floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | This makes the aac decoder and all voice codecs independent of dsputil.
* aacdec: use float planar sample format for outputJustin Ruggles2012-11-25
|
* aac: fix build with hardcoded tablesMans Rullgard2012-10-18
| | | | | | | | | | | aac_tablegen.h includes aac.h for the POW_SF2_ZERO definition, but this also pulls in a raft of other headers, some of which are not safe to use in code built with the host compiler. Moving POW_SF2_ZERO to aac_tablegen_decl.h, where the declaration of the array it relates to already resides, fixes the problems. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Give all anonymously typedeffed structs in headers a nameDiego Biurrun2012-10-06
| | | | Anonymous structs cannot be forward declared and have no benefit.
* Add a float DSP framework to libavutilJustin Ruggles2012-06-08
| | | | Move vector_fmul() from DSPContext to AVFloatDSPContext.
* aacdec: More robust output configuration.Alex Converse2012-04-16
| | | | | | Save the old output configuration (if it has been used successfully) when trying a new configuration. If the new configuration fails to decode, restore the last successful configuration.
* aacdec: Try to sniff a reasonable channel layout for PCE based configurations.Alex Converse2012-02-09
| | | | This changes the output order of multichannel PCE based streams.
* aacdec: Turn off PS for multichannel files that use PCE based configs.Alex Converse2012-01-09
| | | | Fixes al_sbr_cm_48_5.1.mp4.
* Add avcodec_decode_audio4().Justin Ruggles2011-12-02
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* doxygen: fix wrong comment syntax, //< vs. ///<Diego Biurrun2011-08-26
|
* doxygen: Prefer member groups over grouping into modulesReinhard Tartler2011-07-02
| | | | | | | | | Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.
* aacdec: Use float instead of int16_t for ltp_state to avoid needless rounding.Justin Ruggles2011-05-15
|
* aacdec: remove sf_scale and sf_offset.Alex Converse2011-04-27
| | | | | | | Instead, scalefactors are adjusted by the offset amount, removing the need for sf_scale, and the MDCT scales are adjusted to compensate for the higher scalefactors. Floating-point output will be handled by modifying the MDCT scales.
* Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets insteadAlex Converse2011-04-27

* Add AVX FFT implementation.Vitor Sessak2011-04-26
| | | | Signed-off-by: Reinhard Tartler <siretart@tauware.de>
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* aacdec: Reduce the size of buf_mdct.Young Han Lee2011-02-21
| | | | | It was doubled in size for the LTP implementation. This brings it back down to its original size.
* aacdec: Implement LTP support.Young Han Lee2011-02-14
| | | | Ported from gsoc svn.
* Separate format conversion DSP functions from DSPContext.Justin Ruggles2011-02-02
| | | | | | | 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>
* Remove the add bias hack for the C version of DSPContext.float_to_int16_*().Justin Ruggles2011-01-28
|
* aacdec: Rework channel mapping compatibility hacks.Alex Converse2010-09-10
| | | | | | | | | | 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

| | | | | | Fixes issue 1882. Originally committed as revision 23439 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
* Add an HE-AAC v1 decoder.Alex Converse2010-03-08
| | | | | | | | | 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

* Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård2010-03-06
| | | | | | | 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

* AAC: Reduce depth of vlc_spectral tables to 2Måns Rullgård2010-01-13
| | | | | | Up to 6% faster overall on i7, no change on A8. Originally committed as revision 21191 to svn://svn.ffmpeg.org/ffmpeg/trunk
* AAC: Add a global header but output not locked output configuration status.Alex Converse2009-12-02
| | | | Originally committed as revision 20701 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Don't lock the channel output configuration based on the first value seen forAlex Converse2009-11-03
| | | | | | | 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
* Merge FFTContext and MDCTContextMåns Rullgård2009-09-20
| | | | Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Ignore subsequent channel configurations after the first in an AAC file. TheAlex Converse2009-07-10
| | | | | | | 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
