I have to override/repackage two packages now that x264.h is
in a package which leads me into a cycle. Or I repackage
ffmpeg, x264, libx264 locally, not just ffmpeg as before.

I respect your decision, but I can't find the justification.

(lib)x264 packaging has been problematic due to 8bit/10bit
in the past as well and I'm certain it's not an easy package
to be responsible for. In fact I remember that the header
moved around in the packages once before (maybe 2 years ago).
x264's new feature flag to depend on libav* is recent and
is the source of the cycle.
