2013-02-12vorbis: decode directly to the user-provided AVFrameJustin Ruggles
2013-01-21vorbisdsp: change block_size type from int to intptr_t.Ronald S. Bultje
This saves one instruction in the x86-64 assembly.
2013-01-20Move vorbis_inverse_coupling from dsputil to vorbisdspcontext.Ronald S. Bultje
Conveniently (together with Justin's earlier patches), this makes our vorbis decoder entirely independent of dsputil.
2013-01-16lavc: Move vector_fmul_window to AVFloatDSPContextJustin Ruggles
Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2012-12-21miscellaneous typo fixesDiego Biurrun
2012-12-05lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov
It will be useful in the upcoming transition to refcounted AVFrames.
2012-11-20vorbisdec: use float planar sample formatJustin Ruggles
2012-09-14vorbisdec: ensure FASTDIV denominator is never 1Luca Barbato
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.
2012-08-19vorbisdec: remove some pointless commentsMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-06-18vorbisdec: replace div/mod in loop with a counterMans Rullgard
2x speedup of surround decoding on Cortex-A9. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-06-08Add a float DSP framework to libavutilJustin Ruggles
Move vector_fmul() from DSPContext to AVFloatDSPContext.
2012-06-05vorbis: Validate that the floor 1 X values contain no duplicates.Alex Converse
Duplicate values in this vector are explicitly banned by the Vorbis I spec and cause divide-by-zero crashes later on.
2012-04-06cosmetics: Align codec declarationsMartin Storsjö
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>
2012-03-08vorbisdec: avoid invalid memory accessAaron Colwell
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>
2012-03-04avcodec: add a Vorbis parser to get packet durationJustin Ruggles
This also allows for removing some of the Vorbis-related hacks.
2012-03-04vorbisdec: read the previous window flag for long windowsJustin Ruggles
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.
2012-02-25vorbisdec: add a flush() functionJustin Ruggles
clear MDCT overlap buffer and reset previous window mode when seeking
2012-02-16vorbis: Add ff_ prefix to nonstatic symbolsMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2012-02-16dsputil: Add ff_ prefix to the dsputil*_init* functionsMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2012-02-16vlc/rl: Add ff_ prefix to the nonstatic symbolsMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2012-02-03vorbis: fix overflows in floor1[] vector and inverse db table index.Ronald S. Bultje
2012-01-28cosmetics: Remove extra newlines at EOFAlex Converse
2012-01-08vorbis: An additional defense in the Vorbis codec.Chris Evans
Fixes Bug: #190 Chromium Bug: #100543 Related to CVE-2011-3893 Signed-off-by: Reinhard Tartler <siretart@tauware.de>
2012-01-08vorbisdec: Fix decoding bug with channel handlingReinhard Tartler
Fixes Bug: #191 Chromium Bug: #101458 CVE-2011-3895 Signed-off-by: Reinhard Tartler <siretart@tauware.de>
2012-01-08cosmetics: drop some pointless parenthesesDiego Biurrun
2011-12-22Drop ALT_ prefix from BITSTREAM_READER_LE name.Diego Biurrun
The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.
2011-12-03Add avcodec_decode_audio4().Justin Ruggles
Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
2011-11-10vorbisdec: remove AVCODEC_MAX_AUDIO_FRAME_SIZE checkJustin Ruggles
The user could provide a larger buffer, which is already checked separately before writing output.
2011-11-10vorbisdec: remove unneeded buf_size==0 checkJustin Ruggles
2011-11-10vorbisdec: return proper error codes instead of made-up onesJustin Ruggles
2011-10-23cosmetics: remove extra spaces before end-of-statement semi-colonsJustin Ruggles
2011-10-23vorbisdec: check output buffer size before writing outputJustin Ruggles
2011-10-20lavc: use avpriv_ prefix for ff_split_xiph_headers.Anton Khirnov
It's used in lavf.
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.
2011-07-15doxygen: do not include license boilerplate in Doxygen documentationDiego Biurrun
2011-06-21Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample().Justin Ruggles
av_get_bits_per_sample_fmt() is deprecated.
2011-06-07vorbisdec: Restore mistakenly removed debug output.Diego Biurrun
2011-06-03vorbis: Remove non-compiling debug statement.Diego Biurrun
2011-06-03vorbis: Remove pointless DEBUG #ifdef around debug output macros.Diego Biurrun
2011-06-03Replace #ifdef + av_log() combinations by av_dlog().Diego Biurrun
2011-06-03Replace custom debug output functions by av_dlog().Diego Biurrun
2011-05-19Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbisJustin Ruggles
decoders. Based on patches by clsid2 in ffdshow-tryout.
2011-05-12Replace int_fast integer types with their sized standard posix counterparts.Diego Biurrun
The _fast integer types provide no realworld benefits, but may introduce portability issues and are just plain ugly.
2011-04-29vorbis: Replace sized int_fast integer types with plain int/unsigned.Diego Biurrun
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.
2011-04-29vorbisdec: Replace some sizeof(type) by sizeof(*variable).Diego Biurrun
2011-04-27vorbisdec: Rename silly "class_" variable to plain "class".Diego Biurrun
2011-04-25vorbisdec: Employ proper printf format specifiers for uint_fast32_t.Diego Biurrun
libavcodec/vorbisdec.c:543: warning: format ‘%d’ expects type ‘int’, but argument 4 has type ‘uint_fast32_t’ libavcodec/vorbisdec.c:543: warning: format ‘%d’ expects type ‘int’, but argument 5 has type ‘uint_fast32_t’
