OBS Studio 28.0.0 depends on 2 libraries which Funtoo (or Gentoo) doesn't have:

• media-libs/libajantv2
• media-libs/librist

I am creating a separate issue because I thought it wouldn't be good to mix these together with the obs-studio autogen issue. I am still testing the ebuild produced by the autogen and I might need to update some other libraries as part of this subtask.
