$ grep Requires: /usr/lib/pkgconfig/xv.pc Requires: xproto videoproto So "Requires: xorg-x11-proto-devel" seems to be missing in libXv-devel. There's xext and x11 in Requires.private too, so in case Requires.private cannot be dropped, the dependency should be on libXext-devel instead (which will pull in libX11-devel and thus xorg-x11-proto-devel if bug 176078 is fixed as suggested).
Foxed om 1.0.1-2 in rawhide.
