Apparently, they fixed this in a newer version of ffmpeg.

Line from lilliput mem.h (Line 341):
av_alloc_size(2, 3) int av_reallocp_array(void *ptr, size_t nmemb, size_t size);

Line from latest git repo on ffmpeg website (Line 348 at https://git.ffmpeg.org/gitweb/ffmpeg.git/tree/HEAD:/libavutil):
int av_reallocp_array(void *ptr, size_t nmemb, size_t size);

Commit that fixed the issue: https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/4361293fcf59edb56879c36edcd25f0a91e0edf8

I noticed that the same file is being used in the OSX version. Could a ffmpeg version bump fix this?

Same on 20.04 LTS (Focal Fossa) :(

Sounds like the package distros need to be rebuilt with newer ffmpeg? up to date Arch distro affected so doesn't seem like local ffmpeg version matters
