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

Anton Khirnov	6f89efeaa7	lavc: use avpriv_ prefix for ff_ac3_parse_header. It's used in lavf.	13 years ago
Anton Khirnov	145f741e11	AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*	13 years ago
Mans Rullgard	633ddb8519	ac3dec: use get_sbits() instead of manually sign-extending Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	a4ea00d021	lavc/lavf: use unique private classes. This is needed by the new AVOptions API.	13 years ago
Anton Khirnov	feedc0754b	ac3dec: actually use drc_scale private option	13 years ago
Reimar Döffinger	459fe331e9	ac3dec: avoid pointless alloc and indirection for input_buffer Since we now always allocate it, it can simply be made part of the context instead.	14 years ago
Anton Khirnov	9b83919f44	ac3dec: add a drc_scale private option Deprecate corresponding AVCodecContext option. This is the first test of decoder private options.	14 years ago
Justin Ruggles	e6c52cee54	Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample(). av_get_bits_per_sample_fmt() is deprecated.	14 years ago
Justin Ruggles	9aa8193a23	Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbis decoders. Based on patches by clsid2 in ffdshow-tryout.	14 years ago
Justin Ruggles	4c64c8e95a	ac3dec: fix processing of delta bit allocation information. The number of dba segments is the coded value + 1. The coupling dba offset starts at the first coupling band, not at zero.	14 years ago
Mans Rullgard	6d9f52b2cd	ac3: move ff_ac3_bit_alloc_calc_bap to ac3dsp Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	991f3de1bb	ac3enc: Add codec-specific options for writing AC-3 metadata.	14 years ago
Justin Ruggles	be18738801	Get audio_service_type for AC-3 based on bitstream mode in the AC-3 parser and decoder, and vice-versa for the AC-3 encoder.	14 years ago
Reimar Döffinger	4c886d613d	Detect byte-swapped AC-3 and support decoding it directly. This allows the AC-3 decoder to be used directly with RealMedia decoders that unlike the libavformat one do not byte-swap automatically. Since the new code is only used in case we would fail directly otherwise there should be no risk for regressions.	14 years ago
Justin Ruggles	40728b5169	cosmetics: indentation	14 years ago
Justin Ruggles	67fc8652b9	Always copy input data for AC3 decoder. Depending on error_recognition is not correct, low values do certainly not mean it is ok to crash. Based on a patch by Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 years ago
Mans Rullgard	a45fbda994	Move ff_kbd_window_init() to a separate file This function is not tightly coupled to mdct, and it's in the way of making a fixed-point mdct implementation. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	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	80ba1ddb58	Remove unneeded add bias from 3 functions. DSPContext.vector_fmul_window() DCADSPContext.lfe_fir() SynthFilterContext.synth_filter_float() Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	b5ec638343	cosmetics: indentation and spacing	14 years ago
Justin Ruggles	9d06d7bce3	Remove the add bias hack for the C version of DSPContext.float_to_int16_*().	14 years ago
Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	4c57cde942	Add ff_ prefix to ac3_common_init(). Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Stefano Sabatini	2874c81cc8	Replace all remaining occurrences of AVERROR_NOMEM with AVERROR(ENOMEM). AVERROR_NOMEM is deprecated and will be dropped at the next libavutil major bump. Originally committed as revision 22791 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	ca6e7708b4	Add spectral extension to the E-AC-3 decoder. Original patch by Justin, updated and resubmitted by Christophe Gisquet, christophe D gisquet A gmail Originally committed as revision 22734 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Justin Ruggles	535497f193	Change an error to a warning to support broken AC-3 files known to exist. Fixes Issue 1426. Originally committed as revision 20110 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Justin Ruggles	2ed4439658	Simplify stereo rematrixing by only using one temporary variable. It is also about 1.8% faster on my system. Originally committed as revision 20090 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
