Michael Niedermayer	2c22701c37	ac3dec: Check number of output channels. Fixes out of array write. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	a92be9b856	Replace memset(0) by zero initializations. Also remove one pointless zero initialization in rangecoder.c.	13 years ago
Justin Ruggles	3798205a77	mov: set channel layout for AC-3 streams based on the 'dac3' atom info fixes Bug 225	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Michael Niedermayer	e6d9fa66f1	ac3dec: Move center and surround mix level tables to the parser. That way all mix levels as exported by avpriv_ac3_parse_header() will have the same meaning. Previously the 3-bit center mix level for E-AC-3 was used to index in a 4-entry table, leading to out-of-array reads.

Anton Khirnov	f326501a65	lavc: remove disabled FF_API_DRC_SCALE cruft.	13 years ago
Michael Niedermayer	99a42f3fa9	ac3dec: Move center&surround mix level tables to parser. That way all mix levels as exported by the parser will have the same meaning. Previously the 3bit center mix level for eac3 was used to index in a 4 entry table leading to out of array reads. this change removes the table and offsets the ac3 variable by 4 so it matches the meanings for eac3 except the reserved case. The reserved case is then explicitly handled. Idea-by: Justin Ruggles <justin.ruggles@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
Michael Niedermayer	eda3758c87	ac3dec: update checked AV_EF flags. A user who wishes to use default error concealment cannot set the AV_EF_CRCCHECK flag because not every CRC in every format is a reliable indicator of bitstream damage. In some formats crcrs can be nonsensical in absence of any damage. We thus add the AV_EF_CAREFUL flag in addition to the AV_EF_CRCCHECK flag to allow a user to enable this reliable CRC check without having to enable all CRC checks in all formats.

Chris Berov	541d083a40	ac3dec: cosmetics: pretty-printing Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	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
Dustin Brody	9abc98737f	lavc: replace references to deprecated AVCodecContext.error_recognition to use AVCodecContext.err_recognition Signed-off-by: Anton Khirnov <anton@khirnov.net>	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.	13 years ago
Michael Niedermayer	931187e117	ac3dec: export center & suroundmix levels Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 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
Reimar Döffinger	636ee66f1c	Fix data_size handling for AC3 and dca decoders. They use now code identical to the AAC decoder. The AC3 decoder previously did not check the data_size and the dca decoder checked against and set wrong values for float.	14 years ago
Reimar Döffinger	4c7ad768e1	ac3dec: allow selecting float output at runtime.	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

clsid2	0e09997fa4	Libavcodec AC3/E-AC3/DTS decoders now output floating point data. git-svn-id: https://ffdshow-tryout.svn.sourceforge.net/svnroot/ffdshow-tryout@3769 3b938f2f-1a1a-0410-8054-a526ea5ff92c	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

Reimar Döffinger	c9f6eab184	Detect byte-swapped AC-3 (aka DNET) 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. The "buf" pointer needs to be overwritten since otherwise the CRC check fails.	14 years ago
Justin Ruggles	fe2ff6d247	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> (cherry picked from commit `c73d99e672`)	14 years ago
