Luca Barbato	0025f7408a	vorbis: Check the vlc value in setup_classifs The valid returned values are always at most 11bit. Remove the previous check that assumed larger values plausible and use a signed integer to check get_vlc2 return values. CC: libav-stable@libav.org	10 years ago
Luca Barbato	62de77ffca	vorbis: Use a local codebook variable Makes the code a little simpler.	10 years ago
Anton Khirnov	ee964145b5	lavc: remove unused traces of fmtconvert usage Those decoders have been switched to float output and so do not use fmtconvert anymore.	10 years ago
Vittorio Giovara	31dc73e92a	vorbisdec: Check memory allocations	10 years ago
Diego Biurrun	7f9f771eac	avcodec: Don't anonymously typedef structs	10 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Luca Barbato	92b3caa108	vorbis: return meaningful errors	12 years ago
Luca Barbato	db347280eb	vorbis: fallback to normal division instead of crashing The use of ff_inverse speeds up slightly arches + compilers that do not provide a division faster than the whole machinery, such as ppc32 + gcc4.7, but has operational limits. Drop the always-enable assert and provide a fallback.	12 years ago
Luca Barbato	ddf1b4a2f8	vorbis: simplify the inner loop in setup_classifs	12 years ago
Luca Barbato	36f1038004	vorbis: use normal integer values for iterators No need to use fixed-size integers.	12 years ago
Luca Barbato	98186578a2	vorbis: refactor vorbis_residue_decode_internal	12 years ago
Anton Khirnov	e2c2974120	vorbisdec: do not leak the first frame.	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Luca Barbato	02055b6d40	vorbisdec: check memory allocations	12 years ago
Justin Ruggles	e951b6d94c	vorbisdec: cosmetics: rename variable avccontext to avctx This is consistent with the rest of libavcodec.	12 years ago
Luca Barbato	23bd9ef4b2	vorbisdec: Accept 0 amplitude_bits The specification does not prevent an encoder to write the amplitude 0 as 0 amplitude_bits. Our get_bits() implementation might not support a zero sized read properly, thus the additional branch.	12 years ago
Luca Barbato	5b47c19bfd	vorbisdec: Add missing checks Rate and order must not be 0 even if the specification does not say that explicitly.	12 years ago
Luca Barbato	fc386f2eea	vorbisdec: cosmetics Use the commonly used "if (!var)" instead of "if (var == 0)".	12 years ago
Michael Niedermayer	11dcecfcca	vorbisdec: Error on bark_map_size equal to 0. The value is used to calculate output LSP curve and a division by zero and out of array accesses would occur. CVE-2013-0894 CC: libav-stable@libav.org Reported-by: Dale Curtis <dalecurtis@chromium.org> Found-by: inferno@chromium.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Justin Ruggles	ee6ca11b65	vorbis: decode directly to the user-provided AVFrame	12 years ago
Ronald S. Bultje	1768e43ceb	vorbisdsp: change block_size type from int to intptr_t. This saves one instruction in the x86-64 assembly.	12 years ago
Ronald S. Bultje	fef906c77c	Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.	12 years ago
Justin Ruggles	e034cc6c60	lavc: Move vector_fmul_window to AVFloatDSPContext Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Diego Biurrun	511cf612ac	miscellaneous typo fixes	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Justin Ruggles	79b7747556	vorbisdec: use float planar sample format	12 years ago
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
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
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
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
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
