If you can point to any way in which x264's encoding is not compliant, 
please file a bug report. Because I haven't heard of any for about 8 
months.
Even 2 years ago when x264 was just beginning and didn't do much of 
anything and was worse quality than ffmpeg4, it was already 100% 
compliant, it just didn't use all the options allowed by the standard. 
x264 still doesn't use all the options allowed, and neither does anyone 
else, but x264 supports a much larger fraction than quicktime does.

x264 isn't version 1.0, it's version 46.504. Because I don't like to make 
value judgments about one patch being important enough to cause a version 
increment, so they all do. And before you ask about time-based releases, 
go download a snapshot from whatever date you want. No, I won't support 
any particular past version, my answer will always be "use svn" just like 
you hear around here.
