2013-01-20 | ac3dec: fix non-optimal dithering of zero bit mantissas | Mathias Rauen | |

2012-12-05 | lavc: add a wrapper for AVCodecContext.get_buffer(). | Anton Khirnov | |
It will be useful in the upcoming transition to refcounted AVFrames. | |||
2012-10-12 | Use proper return values in case of missing features | Diego Biurrun | |
2012-10-01 | ac3dec: ensure get_buffer() gets a buffer for the correct number of channels | Justin Ruggles | |
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 | |||
2012-09-13 | ac3: move ac3_downmix() from dsputil to ac3dsp | Mans Rullgard | |

2012-03-28 | Replace memset(0) by zero initializations. | Diego Biurrun | |

2012-02-23 | mov: set channel layout for AC-3 streams based on the 'dac3' atom info | Justin Ruggles | |
fixes Bug 225 | |||
2012-02-16 | dsputil: Add ff_ prefix to the dsputil*_init* functions | Martin Storsjö | |
Signed-off-by: Martin Storsjö <martin@martin.st> | |||
2012-02-10 | ac3dec: Move center and surround mix level tables to the parser. | Michael Niedermayer | |
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.

2011-12-03 | Add 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. | |||
2011-10-22 | lavc: replace references to deprecated AVCodecContext.error_recognition to ↵ | Dustin Brody | |
use AVCodecContext.err_recognition Signed-off-by: Anton Khirnov <anton@khirnov.net> | |||
2011-10-20 | lavc: use avpriv_ prefix for ff_ac3_parse_header. | Anton Khirnov | |
It's used in lavf. | |||
2011-10-12 | AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_* | Anton Khirnov | |
2011-10-10 | ac3dec: use get_sbits() instead of manually sign-extending | Mans Rullgard | |
Signed-off-by: Mans Rullgard <mans@mansr.com> | |||
2011-10-05 | lavc/lavf: use unique private classes. | Anton Khirnov | |
This is needed by the new AVOptions API. | |||
2011-09-21 | ac3dec: actually use drc_scale private option | Anton Khirnov | |
2011-09-06 | ac3dec: avoid pointless alloc and indirection for input_buffer | Reimar Döffinger | |
Since we now always allocate it, it can simply be made part of the context instead. | |||
2011-07-10 | ac3dec: add a drc_scale private option | Anton Khirnov | |
Deprecate corresponding AVCodecContext option. This is the first test of decoder private options. | |||
2011-06-21 | Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample(). | Justin Ruggles | |
av_get_bits_per_sample_fmt() is deprecated. | |||
2011-05-19 | Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbis | Justin Ruggles | |
decoders. Based on patches by clsid2 in ffdshow-tryout. | |||
2011-04-17 | ac3dec: fix processing of delta bit allocation information. | Justin Ruggles | |
The number of dba segments is the coded value + 1. The coupling dba offset starts at the first coupling band, not at zero. | |||
2011-03-29 | ac3: move ff_ac3_bit_alloc_calc_bap to ac3dsp | Mans Rullgard | |

2011-03-27 | ac3enc: Add codec-specific options for writing AC-3 metadata. | Justin Ruggles | |
2011-03-25 | Get audio_service_type for AC-3 based on bitstream mode in the AC-3 parser | Justin Ruggles | |
and decoder, and vice-versa for the AC-3 encoder. | |||
2011-03-22 | Detect byte-swapped AC-3 and support decoding it directly. | Reimar Döffinger | |
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. | |||
2011-03-22 | cosmetics: indentation | Justin Ruggles | |
2011-03-22 | Always copy input data for AC3 decoder. | Justin Ruggles | |
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> | |||
2011-03-19 | Move ff_kbd_window_init() to a separate file | Mans Rullgard | |
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> | |||
2011-03-19 | fft: remove inline wrappers for function pointers | Mans Rullgard | |
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> | |||

2011-02-02 | Separate format conversion DSP functions from DSPContext. | Justin Ruggles | |
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> | |||

2011-01-26 | Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. | Diego Elio Pettenò | |
