You need to use "provides" as well. You are essentially trying to provide
an alternative version.
Try using "provides=('ffmpeg')"
>From the wiki:
https://wiki.archlinux.org/title/PKGBUILD
"...If providing an alternate version of an already existing package or
uploading to the AUR, use the conflicts and provides arrays, which are only
evaluated when actually installing the conflicting package."
As an example, see these alternative aur packages for ffmpeg.
https://aur.archlinux.org/packages/ffmpeg-git
https://aur.archlinux.org/packages/ffmpeg-full
