* mov: set channel layout for AC-3 streams based on the 'dac3' atom infoJustin Ruggles2012-02-22
| | | | fixes Bug 225
* dsputil: Add ff_ prefix to the dsputil*_init* functionsMartin Storsjö2012-02-15
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* ac3dec: Move center and surround mix level tables to the parser.Michael Niedermayer2012-02-09
| | | | | | | | | | | | 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.

* Add avcodec_decode_audio4().Justin Ruggles2011-12-02
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* lavc: replace references to deprecated AVCodecContext.error_recognition to ↵Dustin Brody2011-10-22
| | | | | | use AVCodecContext.err_recognition Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavc: use avpriv_ prefix for ff_ac3_parse_header.Anton Khirnov2011-10-20
| | | | It's used in lavf.
* AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*Anton Khirnov2011-10-12

* ac3dec: use get_sbits() instead of manually sign-extendingMans Rullgard2011-10-09
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* lavc/lavf: use unique private classes.Anton Khirnov2011-10-05
| | | | This is needed by the new AVOptions API.
* ac3dec: actually use drc_scale private optionAnton Khirnov2011-09-21
|
* ac3dec: avoid pointless alloc and indirection for input_bufferReimar Döffinger2011-09-06
| | | | | Since we now always allocate it, it can simply be made part of the context instead.
* ac3dec: add a drc_scale private optionAnton Khirnov2011-07-10
| | | | | | Deprecate corresponding AVCodecContext option. This is the first test of decoder private options.
* Replace usages of av_get_bits_per_sample_fmt() with av_get_bytes_per_sample().Justin Ruggles2011-06-20
| | | | av_get_bits_per_sample_fmt() is deprecated.
* Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbisJustin Ruggles2011-05-18
| | | | | | decoders. Based on patches by clsid2 in ffdshow-tryout.
* ac3dec: fix processing of delta bit allocation information.Justin Ruggles2011-04-17
| | | | | The number of dba segments is the coded value + 1. The coupling dba offset starts at the first coupling band, not at zero.
* ac3: move ff_ac3_bit_alloc_calc_bap to ac3dspMans Rullgard2011-03-29

* Get audio_service_type for AC-3 based on bitstream mode in the AC-3 parserJustin Ruggles2011-03-25
| | | | and decoder, and vice-versa for the AC-3 encoder.
* Detect byte-swapped AC-3 and support decoding it directly.Reimar Döffinger2011-03-22
| | | | | | | 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.
* cosmetics: indentationJustin Ruggles2011-03-22

* Always copy input data for AC3 decoder.Justin Ruggles2011-03-22
| | | | | | | 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>
* Move ff_kbd_window_init() to a separate fileMans Rullgard2011-03-19
| | | | | | | 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>
* fft: remove inline wrappers for function pointersMans Rullgard2011-03-19
| | | | | | | 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>

* Separate format conversion DSP functions from DSPContext.Justin Ruggles2011-02-02
| | | | | | | 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>
* Remove unneeded add bias from 3 functions.Justin Ruggles2011-01-31

|
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
