I hope I never used the word "idiot", even if on some days I think it
(and I hope you will forgive me my unfriendly thoughts :-) ).
Anyway, on Windows compiling unfortunately is a somewhat advanced topic,
particularly if you want it to actually work well.
Which is why most people should just use some binary, for Windows even
up-to-date ones are not that hard to get.

I'd say you're not bad at compiling stuff :-)

What you missed is the reason why these failed: configure did not
find a pthread library, so look for that check and find out why it
failed.

Well, getting and linking against a libx264.dll if such a thing exists
might work at well, but performance might be somewhat worse.

See what the "pthread" check says in configure.log, and if that does not
help you further give us the output of that.
