* avcodec/motion_est_template: Avoid using last + 1 element of arrayAndreas Rheinhardt2022-10-241-1/+1
| | | | | | | | | | | | | | | | | | For an int array[8][2] using &array[8][0] (which is an int* pointing to the element beyond the last element of array) triggers a "runtime error: index 8 out of bounds for type 'int[8][2]'" from (Clang-)UBSan in the fate-vsynth(1|2|_lena)-snow tests. I don't know whether this is really undefined behaviour or does not actually fall under the "pointer arithmetic with the element beyond the last element of the array is allowed as long as it is not accessed" exception". All I know is that the code itself does not read from beyond the last element of the array. Nevertheless rewrite the code to a form that UBSan does not complain about.

* avcodec/motion_est, mpegvideo: Make pointers to static storage constAndreas Rheinhardt2020-12-311-1/+1
| | | | | | | | | Modifying static storage must not happen because of multithreading (except initialization of course), so add const to the pointed-to type for pointers that point to static storage.

| | | | | | | | | | | | | | | | | | This code is in a performance critical section. AV_QSORT is substantially faster due to the inlining of the comparison callback.

| * motion_est: fix use of inline on extern functionsMans Rullgard2012-09-201-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inline functions declared without extern do not provide an external definition in standard C99. This code only works because most compilers do not implement the inline semantics correctly. With a stricter compiler, linking fails with unresolved references to these functions. Declaring the functions extern inline works correctly with some compilers while some others still fail to create external definitions. For maximum portability, create a static inline version with an externally visible wrapper for ff_get_mb_score. ff_epzs_motion_search is so large that no sane compiler inlines it anyway, so there the inline keyword can simply be dropped with no effect.
