Luca Barbato	714508bcb9	vorbisdec: ensure FASTDIV denominator is never 1 In both usages of FASTDIV the denominator might be 1. Using a branch could make the function slower than using a normal division. Both denominator and numerator can be multiplied by 2 safely and using shifts is faster than using a branch.	12 years ago
Mans Rullgard	4855022aa1	vorbisdec: remove some pointless comments Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Michael Niedermayer	8cac86e091	vorbisdec: fix heap buffer overflow. Found-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	5f298c6791	vorbisdec: switch to av_assert Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	9fcda25e35	vorbisdec: replace div/mod in loop with a counter 2x speedup of surround decoding on Cortex-A9. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Alex Converse	ecf79c4d3e	vorbis: Validate that the floor 1 X values contain no duplicates. Duplicate values in this vector are explicitly banned by the Vorbis I spec and cause divide-by-zero crashes later on.	13 years ago
Reimar Döffinger	4561feb4bf	vorbisdec: use correct channels variable. All code should use the local variable, the AVCodecContext might not yet have the updated value. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Aaron Colwell	12623a8026	vorbisdec: avoid invalid memory access This fixes some invalid memory access caused later in the function by res_chan[] not being set for all channels. This happens when a channel doesn't appear a submap. This change simply returns a decoder error when this situation is detected. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Justin Ruggles	5602a464c9	avcodec: add a Vorbis parser to get packet duration This also allows for removing some of the Vorbis-related hacks.	13 years ago
Justin Ruggles	737ca4482b	vorbisdec: read the previous window flag for long windows When reading sequentially, we are using the actual flag from the previous frame, but when seeking we do not know what the previous window flag was, so we need to read it from the bitstream.	13 years ago
Justin Ruggles	19adb0bc2d	vorbisdec: add a flush() function clear MDCT overlap buffer and reset previous window mode when seeking	13 years ago
Martin Storsjö	27cfdc3e4f	vorbis: Add ff_ prefix to nonstatic symbols Signed-off-by: Martin Storsjö <martin@martin.st>	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
Martin Storsjö	e96b4a53df	vlc/rl: Add ff_ prefix to the nonstatic symbols Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Ronald S. Bultje	24947d4988	vorbis: fix overflows in floor1[] vector and inverse db table index.	13 years ago
Alex Converse	7181c4edee	cosmetics: Remove extra newlines at EOF	13 years ago
Michael Niedermayer	ebc9ff8e7d	vorbisdec: Check that the x values of floor1 are unique. This is required by the spec and fixes video-1frag.ogg.48.ogg. (FPE) Based on the debuging work of Oana Stratulat and ubitux. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Chris Evans	afb2aa5379	vorbis: An additional defense in the Vorbis codec. Fixes Bug: #190 Chromium Bug: #100543 Related to CVE-2011-3893 Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Reinhard Tartler	e6d527ff72	vorbisdec: Fix decoding bug with channel handling Fixes Bug: #191 Chromium Bug: #101458 CVE-2011-3895 Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
Michael Niedermayer	ff7f198d7f	vorbis: make sure ch is non zero before calling vorbis_residue_decode This possibly makes part of the CVE-2011-3895 fix unneeded. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Chris Evans	f74ce3a60d	vorbis: An additional defense in the Vorbis codec. BUG=101458 Review URL: http://codereview.chromium.org/8414025 Fixes second part of CVE-2011-3895 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	405e99bdfd	vorbisdec: Make sure blocksize is not set to an invalid value. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	aaf47bcde7	Drop ALT_ prefix from BITSTREAM_READER_LE name. The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.	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
Justin Ruggles	41899b9acb	vorbisdec: remove AVCODEC_MAX_AUDIO_FRAME_SIZE check The user could provide a larger buffer, which is already checked separately before writing output.	13 years ago
Justin Ruggles	e551a6f49a	vorbisdec: remove unneeded buf_size==0 check	13 years ago
Justin Ruggles	f666276fa6	vorbisdec: return proper error codes instead of made-up ones	13 years ago
Justin Ruggles	b95fbba705	cosmetics: remove extra spaces before end-of-statement semi-colons	13 years ago
Justin Ruggles	60aa1a358d	vorbisdec: check output buffer size before writing output	13 years ago
Anton Khirnov	357db4c263	lavc: use avpriv_ prefix for ff_split_xiph_headers. It's used in lavf.	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Diego Biurrun	6168781f70	doxygen: do not include license boilerplate in Doxygen documentation	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

Diego Biurrun	df96f22d8f	Replace custom debug output functions by av_dlog().	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
Diego Biurrun	0a6b1a9f21	Replace int_fast integer types with their sized standard posix counterparts. The _fast integer types provide no realworld benefits, but may introduce portability issues and are just plain ugly.	14 years ago
Diego Biurrun	cf3ac54339	vorbis: Replace sized int_fast integer types with plain int/unsigned. int/unsigned is the natural memory access type for CPUs, using sized types for temporary variables, counters and similar just increases code size and can possibly cause a slowdown.	14 years ago
Diego Biurrun	d1be646e90	vorbisdec: Replace some sizeof(type) by sizeof(*variable).	14 years ago
Carl Eugen Hoyos	b35a846923	Change silly variable name "class" to "partition_class".	14 years ago
Diego Biurrun	b239526873	vorbisdec: Rename silly "class_" variable to plain "class".	14 years ago
Reimar Döffinger	5aff31b136	vorbisdec: allow selecting float output at runtime.	14 years ago
