Aurelien Jacobs	67f718bd11	Add a temp variable to ff_sine_window_init() to match the way wma.c computed window before r14757. This fixes a regression introduced by r14757 on amd64. Originally committed as revision 14982 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	47698b83fd	The ff_sine_#[] should be aligned as they will commonly be used in dsputil functions Originally committed as revision 14767 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	69fc4da360	Add declarations for the sine tables used in wma.c (half window sizes: 128, 256, 512, 1024 and 2048) to mdct.c. Make them accessible via dsputil.h. Make wma.c use these shared tables. Originally committed as revision 14758 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
