* aacenc: Add stereo_mode option.Nathan Caldwell2011-06-021-3/+29
| | | | | | ms_off is the default, until Mid/Side is no longer buggy. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* psymodel: Remove wrapper functions.Nathan Caldwell2011-05-081-3/+3
| | | | Instead use the function pointers directly.
* aacenc: Replace loop counters in aac_encode_frame() with more descriptive ↵Nathan Caldwell2011-05-081-26/+25
| | | | 'ch' and 'w'.
* aacenc: Finish 3GPP psymodel analysis for non mid/side cases.Nathan Caldwell2011-04-231-1/+3
| | | | | | | | | 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>
* Move sine windows to a separate fileMans Rullgard2011-03-201-0/+1
| | | | | | | 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>
* Move ff_kbd_window_init() to a separate fileMans Rullgard2011-03-191-0/+1
| | | | | | | 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 Rullgard2011-03-191-2/+2
| | | | | | | 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>
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-191-4/+4
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* aacenc: Fix a segfault in search_for_quantizersNathan Caldwell2011-03-081-1/+0
| | | | | | | | 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>
* aacenc: remove the data arraysYoung Han Lee2011-03-071-13/+15
| | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-261-1/+1
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* aacenc: fix typo in sync extension constant in 8ae0fa2Janne Grunau2011-01-231-1/+1

* Change DSPContext.vector_fmul() from dst=dst*src to dest=src0*src1.Justin Ruggles2011-01-221-1/+1
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* aacenc: mark SBR absentAlex Converse2011-01-221-2/+7
| | | | | | | Use backwards compatible explicit signalling to denote the absence of SBR. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
* Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enumStefano Sabatini2010-11-121-1/+1

| | | | Originally committed as revision 24099 to svn://svn.ffmpeg.org/ffmpeg/trunk
* aacenc: replace VLA with fixed sizeMåns Rullgård2010-07-061-2/+4
| | | | | | | 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
* aacenc: Start the lookahead pointer 1/4 of the way into the first short window.Alex Converse2010-06-281-1/+1

* Set cur_channel in the AAC encoder context where needed.Alex Converse2010-05-111-0/+2
| | | | | | | 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

* Support for getting (i)MDCT output multiplied by a constant scaling factor.Siarhei Siamashka2009-05-161-2/+2
