This breaks build here

libavutil/mem.c: In function ‘av_malloc’:
libavutil/mem.c:108:15: error: implicit declaration of function ‘aligned_malloc’; did you mean ‘aligned_alloc’? [-Werror=implicit-function-declaration]
         ptr = aligned_malloc(size, ALIGN);
               ^~~~~~~~~~~~~~
               aligned_alloc
libavutil/mem.c:108:13: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
         ptr = aligned_malloc(size, ALIGN);
             ^
cc1: some warnings being treated as errors
