Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	89eea6df28	aacenc: make sure to encode enough frames to cover all input samples. Currently, any samples in the final frame are not decoded because they are only represented by one frame instead of two. So we encode two final frames to cover both the analysis delay and the MDCT delay.	13 years ago
Justin Ruggles	f44005b610	aacenc: only use the number of input samples provided by the user. Fixes handling of CODEC_CAP_SMALL_LAST_FRAME.	13 years ago
Mans Rullgard	3715d841a6	Fix non-C89 declarations in for loops Some compilers still do not support this syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Nathan Caldwell	2e626dd513	aacenc: Fix LONG_START windowing. Forgot to add the equivalent amount to the incoming sample pointer as the output pointer. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Nathan Caldwell	dc7e7d4dd9	aacenc: Fix a bug where deinterleaved samples were stored in the wrong place. 10l: Forgot to adjust deinterleave for new location of incoming samples in `7946a5a`. This produced incorrect, but surprisingly listenable results. Thanks to Justin Ruggles for the report. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Alex Converse	efe68076da	aacenc: Fix identification padding when the bitstream is already aligned.	13 years ago
Michael Niedermayer	cdfe94c5ab	aacenc: Write correct length for long identification strings. When the length is the escape value (15), the new length is calculated by 15 + get_bits(8) - 1. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Nathan Caldwell	9292fe4a1d	aacenc: Simplify windowing Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago

Nathan Caldwell	9b8e2a8709	aacenc: Deinterleave input samples before processing. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago

Nathan Caldwell	80d44277e6	aacenc: Move Q^3/4 calculation to it's own table This should be moved to tablegen at some point. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Nathan Caldwell	025ccf1f8b	aacenc: Request normalized float samples instead of converting s16 samples to float. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Nathan Caldwell	5310704190	aacenc: cosmetics: move init() and end() to the bottom of the file. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Nathan Caldwell	17ae608127	aacenc: aac_encode_init() cleanup Macroify sanity checks and check return values of allocs and other functions. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
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.

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

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
