I just synced my ebuilds and ran into an ffmpeg conflict with two major parents: - `sci-libs/opencascade` which requires <ffmpeg-5 (aka ffmpeg 4) because of https://tracker.dev.opencascade.org/view.php?id=32871 - and `media-video/obs-studio which requires ffmpeg-6 (latest) Is there a reason why obs-studio has to pull ffmpeg-6? (Please see https://bugs.gentoo.org/909566#c6)

You don't have USE=opus enabled on ffmpeg. Please turn it on.
Looking at it now, seems like --autounmask-write added the opus use flag for >=media-video/ffmpeg-6.0-r5 instead of the already installed, obs-studio compatible ffmpeg: ``` # required by media-video/obs-studio-29.1.3-r1::gentoo # required by @selected # required by @world (argument) >=media-video/ffmpeg-6.0-r5 opus ``` Is it a feature for autounmask to pull the latest atom, even though there is a conflict between certain versions? Or perhaps this could be very well a new feature request - to check if a conflicting package has the same USE flags and check which is compatible with both packages and which is the latest of these compatible atoms. At the end of the day, ffmpeg-4.4.4 was already installed on my system, so no downgrades here.
There's --autounmask-unrestricted-atoms but it doesn't do quite what you want.
