* avfilter/vf_nnedi: Fix segfault when prescreening is disabledAndreas Rheinhardt2021-01-24
| | | | | | | | | | | | | | | | | | | | | Since c737f6edcef74a64f4d0ebcefa970bd31266d512 prescreening is nevertheless run because of a wrong check: "if (s->prescreen > 0)". s->prescreen is an array of two function pointers that is contained in the context and comparing it with 0 (i.e. NULL) is actually undefined behaviour, because NULL and s->prescreen do not point to the same object (NULL after all never points to any object). Nevertheless both Clang as well as GCC compile this to code that treat s->prescreen > 0 as true, leading to segfaults, because the code then tries to access the -1th member of an array. This commit fixes the check as well as another such check a few lines below. (Found via compiler warnings enabled by -pedantic: "ordered comparison between pointer and zero is an extension".)
