Comment (by zanderpower@…):

 From what I have gleaned, it seems that x265 is unstable--at best--on
 PowerPCs. See[https://bitbucket.org/multicoreware/x265/issues/85/fallback-
 for-atomic-ops-usage] and [http://www.calculate-linux.org/packages/media-
 libs/x265] and these examples appear to be referring to 64-bit (running
 Linux at that).

 The most optimistic info I have found so far is
 [https://groups.google.com/forum/#!topic/linux.debian.bugs.dist/w_gcORP9768].
 And as before, this is (Debian) Linux.

 I don't know if this gives you any ideas.  I'm not sure what they mean by
 "atomic", unless there is some assembly code that must be implemented to
 work around the problem, or some library that needs to be linked
 ("-latomic"?).

 Again, I am fine with a ffmpeg variant that lacks x265, until another
 option becomes viable (if it ever does).
