Description:

Recently a hard dependency was added to the mpv package for libjpeg-turbo. This makes mpv incompatible with other libjpegs that have the same drop-in ABI, e.g. mozjpeg.

Please swap out the dependency to be for libjpeg instead. See for example gdk-pixbuf2 (which is required by a ton of packages):

https://www.archlinux.org/packages/extra/x86_64/gdk-pixbuf2/ and

https://github.com/archlinux/svntogit-packages/blob/packages/gdk-pixbuf2/trunk/PKGBUILD

Additional info:
* mpv 1:0.33.0-2
This task depends upon

I incorrectly said "required". I meant that the mozjpeg package already *provides* libjpeg-turbo. And yet any package directly requiring libjpeg-turbo is trying to install it.

I personally have 49 of the 128 repository packages depending on a libjpeg installed, and all of them except mpv appear to depend on libjpeg (because they're not incompatible with mozjpeg). My understanding was that depending on libjpeg was a best practice.

Can you have a look at the PKGBUILD? https://aur.archlinux.org/packages/mozjpeg/ If you know how to resolve the conflict on my end, please let me know.

mpv links to libjpeg, not libturbojpeg, therefore it's reasonable for it to depend on libjpeg, not libjpeg-turbo. It might not be the only such package with that distinction.

mpv does not, presumably, care about the libturbojpeg API, only the libjpeg one... :)

@Eli: is there anything I can do to make the mozjpeg PKGBUILD more compatible with packages that require libjpeg-turbo. I'm already providing it as you can see here: https://aur.archlinux.org/packages/mozjpeg/

I think it's quite possible that I'm just forgetting something stupid. I know I've done AUR packages in the past that provided drop-in replacements for a repo package, and they worked fine. Something complex going on with libjpeg vs libjpeg-turbo that I'm not quite seeing.
