Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Justin Ruggles	d7c450436f	ac3dec: validate channel output mode against channel count Damaged frames can lead to a mismatch, which can cause a segfault due to using an incorrect channel mapping. CC:libav-stable@libav.org	12 years ago

Mathias Rauen	04ea5491a8	ac3dec: fix non-optimal dithering of zero bit mantissas Use a noise range of -0.707 to 0.707 instead of -0.5 to 0.5 Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago

Diego Biurrun	717addecad	Use proper return values in case of missing features	12 years ago
Justin Ruggles	56b6a43056	ac3dec: ensure get_buffer() gets a buffer for the correct number of channels If there is an error during frame parsing, but AVCodecContext.channels was changed and AC3DecodeContext.out_channels was set previously, the two may not match. Fixes CVE-2012-2802 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Mans Rullgard	97cb9236cf	ac3: move ac3_downmix() from dsputil to ac3dsp Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	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.

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.	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

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
