* Add ff_init_ff_cos_tabs function and use it in rdft.c to ensure that theReimar Döffinger2009-11-051-9/+15
| | | | | | | necessary ff_cos_tabs tables are initialized. Fixes issue 1507 (QDM2 broken since r20237 without hardcoded tables). Originally committed as revision 20464 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Pad ff_cos_tabs and ff_sin_tabs so that index n points to the table for n bits.Reimar Döffinger2009-11-041-1/+2
| | | | | | | While this "wastes" up to 2x32 bytes it makes the code slightly simpler and less confusing. Originally committed as revision 20449 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move/add COSTABLE/SINTABLE macros to dsputil to add extern definitionsReimar Döffinger2009-10-151-24/+15
| | | | | | for ff_cos_* and ff_sin_* without introducing too much code duplication. Originally committed as revision 20243 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use hardcoded instead of runtime-calculated ff_cos_* tables ifReimar Döffinger2009-10-141-13/+26
| | | | | | | --enable-hardcoded-tables was used. Due to the size, the code for the tables is generated at compile time. Originally committed as revision 20232 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Prepare for optimised forward MDCT implementationsMåns Rullgård2009-09-111-0/+1
| | | | | | | | | This adds a function pointer for forward MDCT to FFTContext and initialises it with the existing C function. ff_calc_mdct() is changed to an inline function calling the selected version as done for other fft/mdct functions.
