ffmpeg-git version on archlinux causing troubles on updates

[Parakovsky]

felas, i got this error every time it asking me to update packages. since for my other needs i would prefer to keep the git version over default pacman version I would like to know if that is anything I should worry about. thank you.

Hi @Parakovsky ! opam tries to do its best to use system packages for dependencies like these. It works for most users. If you are installing a custom ffmpeg, you can consider that you know what you are doing. In this case, opam will give you a warning that you can, indeed, ignore.

Dear @toots I know you are working hard to keep this amazing software as sofisticated as possible, but you probably misunderstood me - which is no problem as I myself misunderstand myself all the time. Unfortunately, there are no way I know around that problem but to revert back to default ffmpeg packaging, which are not huge pain in you know where, but I would like to know one day where to go to fix this to make it work with a git version. Have an excellent day my friend.

Hi @Parakovsky,

I can recommend you to ask the same question in the https://github.com/ocaml/opam discussions, probably they are already aware of this kind of problem and can give you a more consistent advice.

As for the package, if I were you, I would try to patch and pin the conf-ffmpeg package.

Please have a look at the opam packaging documentation at https://opam.ocaml.org/doc/Packaging.html.

Alternatively, you can patch archlinux packages. For example, you could rename the ffmpeg-git package to ffmpeg, prevent the package from being updated, and maintain it manually.
Or you could make a copy of the ffmpeg package repository and build your own package by putting the desired git commit into it.

Thanks this looks like something I would need, cheers!
