Alex Converse	d615187f74	aacdec: Support for ER AAC ELD 480. Based in part on work from Niel van der Westhuizen <espes@pequalsnp.com>.	10 years ago
Alex Converse	b3be41ca82	aac: Add support for Enhanced AAC Low Delay (ER AAC ELD). This does not include support for LD SBR, epTool, data resilience, nor the 960 transform family.	11 years ago
Alex Converse	1914e6f010	aacdec: Add support for LD (Low Delay) AAC	11 years ago
Diego Biurrun	03039f4c8c	miscellaneous typo fixes	11 years ago
Diego Biurrun	c242bbd8b6	Remove unnecessary dsputil.h #includes	12 years ago
Justin Ruggles	ffd2123095	aac: decode directly to the user-provided AVFrame	12 years ago
Ronald S. Bultje	d56668bd80	floatdsp: move scalarproduct_float from dsputil to avfloatdsp. This makes the aac decoder and all voice codecs independent of dsputil.	12 years ago
Justin Ruggles	3d3cf6745e	aacdec: use float planar sample format for output	12 years ago
Mans Rullgard	7a12d97eb1	aac: fix build with hardcoded tables 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>	12 years ago
Diego Biurrun	e4cbf7529b	Give all anonymously typedeffed structs in headers a name Anonymous structs cannot be forward declared and have no benefit.	12 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Alex Converse	9fb7e14635	aacdec: More robust output configuration. 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.	13 years ago
Alex Converse	37bed6ff3f	aacdec: Try to sniff a reasonable channel layout for PCE based configurations. This changes the output order of multichannel PCE based streams.	13 years ago
Alex Converse	4acd43a295	aacdec: Turn off PS for multichannel files that use PCE based configs. Fixes al_sbr_cm_48_5.1.mp4.	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Diego Biurrun	0249478756	doxygen: fix wrong comment syntax, //< vs. ///<	13 years ago
Reinhard Tartler	21a19b7912	doxygen: Prefer member groups over grouping into modules 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.	14 years ago
Justin Ruggles	033a4a942a	aacdec: Use float instead of int16_t for ltp_state to avoid needless rounding.	14 years ago
Alex Converse	767848d761	aacdec: remove sf_scale and sf_offset. 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.	14 years ago
Alex Converse	d70fa4c423	Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets instead of hardcoding 200 everywhere.	14 years ago
Vitor Sessak	9d35fa520e	Add AVX FFT implementation. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Young Han Lee	e22910b21a	aacdec: Reduce the size of buf_mdct. It was doubled in size for the LTP implementation. This brings it back down to its original size.	14 years ago
Young Han Lee	ead15f1dc1	aacdec: Implement LTP support. Ported from gsoc svn.	14 years ago
Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. 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>	14 years ago
Justin Ruggles	9d06d7bce3	Remove the add bias hack for the C version of DSPContext.float_to_int16_*().	14 years ago
Alex Converse	bb2d8e9f05	aacdec: Rework channel mapping compatibility hacks. 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	14 years ago
Alex Converse	c909d48266	Whitespace cosmetics Originally committed as revision 23491 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Alex Converse	7caee063a0	aacdec: Work around illegal files with all elem_id tags set to the same value. Fixes issue 1882. Originally committed as revision 23439 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Alex Converse	ed492b61db	Add an HE-AAC v1 decoder. 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	15 years ago

Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros 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	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Alex Converse	981b8fd777	Don't lock the channel output configuration based on the first value seen for 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	15 years ago
Måns Rullgård	01b2214758	Merge FFTContext and MDCTContext Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	6308765cb5	Ignore subsequent channel configurations after the first in an AAC file. The 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	16 years ago
Alex Converse	78e65cd772	Merge the AAC encoder from SoC svn. It is still considered experimental. Originally committed as revision 19375 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Robert Swain	b17f1a0764	Doxygen defgroups throw a warning if they don't have a title as well as a name Originally committed as revision 16939 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. 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	16 years ago
