Thanks for tracking down the issue... sorry about the stdint.h being
the cause...  hopefully we'll be able to find a solution that works
across the board.

I've removed "~/Library/Frameworks" and "/Library/Frameworks" from
'FindFFmpeg.cmake' and am re-compiling now.

Would FFmpeg ever be a framework?  Would it be fine just to roll this
into svn/trunk?

Unfortunately it didn't solve the problem. Even with those gone 'stdint.h' is still found in /System/Library/Frameworks/Kernel.framework even though '/System/Library' isn't even searched (and was not before).

Searching in /System/Library/Frameworks is apparently default behaviour for 
FIND_PATH().

There are ways to tweak that: include NO_DEFAULT_PATH in FIND_PATH(...) or check frameworks last, after the standard libraries. I chose the latter since it's hopefully less likely to break things for anyone else.

Cheers,
