avcodec/aacsbr_template: Remove pointless runtime initialization The sbr_qmf_window_us array is basically symmetric around its middle element and therefore the latter half is currently initialized from the first half at runtime. Yet because the first half is initialized, the array can't be placed in .bss at all, so that one gains nothing from not already initializing the whole array statically. Therefore this commit does exactly this. (There are two exceptions to the symmetry: Elements 384 and 512 are the negations of their mirror element; for the fixed-point decoder, Q31(-x) does not equal -Q31(x). In order to keep the array exactly the same, the latter form has been used for these two elements.) Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

avcodec/aacsbr_template: Remove pointless runtime initialization The sbr_qmf_window_us array is basically symmetric around its middle element and therefore the latter half is currently initialized from the first half at runtime. Yet because the first half is initialized, the array can't be placed in .bss at all, so that one gains nothing from not already initializing the whole array statically. Therefore this commit does exactly this. (There are two exceptions to the symmetry: Elements 384 and 512 are the negations of their mirror element; for the fixed-point decoder, Q31(-x) does not equal -Q31(x). In order to keep the array exactly the same, the latter form has been used for these two elements.) Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
