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

Diego Elio Pettenò	e7e2df27f8	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> (cherry picked from commit `d36beb3f69`)	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	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
