Anton Khirnov	9f51c682ee	lavc: use avpriv_ prefix for ff_copy_bits and align_put_bits. They are used in lavf.	13 years ago
Anton Khirnov	59a9a23581	lavc: use avpriv_ prefix for some mpeg4audio symbols used in lavf. Specifically, ff_mpeg4audio_sample_rates, ff_mpeg4audio_get_config and ff_copy_pce_data	13 years ago
Anton Khirnov	145f741e11	AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*	13 years ago
Nathan Caldwell	24efdea7fd	aacenc: Fix number of coefficients used in a LFE channel. The spec states: * Only the lowest 12 spectral coefficients of any LFE may be non-zero We were using the 12 lowest bands.	13 years ago
Nathan Caldwell	51a1d4d94a	aacenc: Fix a segfault with grouped psymodel. 10l: Forgot about TYPE_LFE being after TYPE_CPE. Which causes a segfault when encoding 5.1	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
Nathan Caldwell	98add74e85	aacenc: Fix determination of Mid/Side Mode. In adjust_frame_information(), msc is incremented for each sfb in each sub-window then compared against max_sfb which is for a single sub-window. This resulted in frames using EIGHT_SHORT_SEQUENCE where the first few sub-windows increment msc to a value that results in ms_mode == 2. Even though only some of the bands are actually using Mid/Side.	14 years ago
Nathan Caldwell	d3a6c2ab7e	psymodel: Remove the single channel analysis function	14 years ago
Nathan Caldwell	01344fe409	aacenc: Implement dummy channel group analysis that just calls the single channel analysis for each channel.	14 years ago
Nathan Caldwell	0bc01cc9fe	psymodel: Add channels and channel groups to the psymodel.	14 years ago
Nathan Caldwell	1bb52045d3	aacenc: Save channel configuration for later use.	14 years ago
Nathan Caldwell	cc9947ffbe	aacenc: Add stereo_mode option. ms_off is the default, until Mid/Side is no longer buggy. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Nathan Caldwell	b58e298572	psymodel: Remove wrapper functions. Instead use the function pointers directly.	14 years ago
Nathan Caldwell	5b29af624f	aacenc: Replace loop counters in aac_encode_frame() with more descriptive 'ch' and 'w'.	14 years ago
Nathan Caldwell	230c1a9075	aacenc: Finish 3GPP psymodel analysis for non mid/side cases. There is still are still a few sections missing relating to TNS (not present) and mid/side (contains other bugs). Overall this improves quality, and vastly improves rate-control. Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Mans Rullgard	4538729afe	Move sine windows to a separate file These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	a45fbda994	Move ff_kbd_window_init() to a separate file 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>	14 years ago
Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers 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>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Nathan Caldwell	31ff9bd7b8	aacenc: Fix a segfault in search_for_quantizers This reverts the removal of scoefs from AACEncContext. It resulted in scoefs being a NULL pointer when search_for_quantizers() is called. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Young Han Lee	2790d7a9ff	aacenc: remove the data arrays Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Janne Grunau	2fd9035ddc	aacenc: fix typo in sync extension constant in `8ae0fa2`	14 years ago
Justin Ruggles	6eabb0d3ad	Change DSPContext.vector_fmul() from dst=dstsrc to dest=src0src1. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Alex Converse	1297f58132	aacenc: Don't set s->cur_channel before apply_window_and_mdct(). In general s->cur_channel should be phased out. Originally committed as revision 25001 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Nathan Caldwell	0045499dec	aacenc: Refactor apply_window_and_mdct() so it no longer takes an offset channel. Patch by Nathan Caldwell <saintdev@gmail.com> Originally committed as revision 24331 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	86e41bc300	aacenc: replace VLA with fixed size Number of channels is restricted to 6 so the size is acceptable for the stack. Originally committed as revision 24068 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	4e42debc8d	aacenc: Start the lookahead pointer 1/4 of the way into the first short window. Short windows are of length 256 and begin at sample 448. Originally committed as revision 23871 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Alex Converse	495af353db	Set cur_channel in the AAC encoder context where needed. Most coder functions read it. Carting this around in the context may be suboptimal; a refactor should be considered. Originally committed as revision 23094 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	217b44ddc3	Error out when too many bits per frame are requested. Originally committed as revision 23036 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands.
