The current ~ version of mpv (0.23.0) causes a block on systems with libav due to the following requirement in the ebuild: https://gitweb.gentoo.org/repo/gentoo.git/tree/media-video/mpv/mpv-0.23.0.ebuild COMMON_DEPEND=" !libav? ( >=media-video/ffmpeg-3.2.2:=[encode?,threads,vaapi?,vdpau?] ) libav? ( >=media-video/libav-12:=[encode?,threads,vaapi?,vdpau?] ) libav-12 is currently masked, according to: https://packages.gentoo.org/packages/media-video/libav The only workaround that I found was to manually mask =media-video/mpv-0.23.0 Cheers, Nathan Zachary
mpv-0.23.0 won't be masked globally because it works with ffmpeg. mpv-0.23.0[libav] is already masked in profiles: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=650307c005a5b13fb12df67a7d3fcc7439d3e033 Sorry, but libav users have to wait until bug 603726 is resolved. I've seen the blocker you are talking about, but sadly portage doesn't show the reason for USE masks as it does for package masks. There's a bug 497166 for it. If only there was a profile (or smth) for libav, where I could pmask mpv...
In the meantime I suggest to either locally unmask both libav-12 and mpv-0.23.0[libav], or locally pmask mpv-0.23.0.
