Hi all,
When trying to encode a movie on Mountain Lion using the libx264 codec ffmpeg
segfaults with return code 139. And why is this -strict option needed?

Please try the attached file. Save it to
/sw/fink/dists/local/main/finkinfo and rebuild libx264 with
fink install libx264-118-shlibs
then try your ffmpeg command again. You should not need to rebuild
ffmpeg if this fix works.
As for the -strict flag requirement, I don't know as I've never used it.
ffmpeg-users might be a better place to discuss that once your x264 is
working.

Description: Encoding H264/AVC video stream shared library
DescDetail: <<
x264 is a free library for encoding H264/AVC video streams
<<
DescPackaging: <<
Starting with library version -98-, the -dev splitoff is named to match the
-shlibs splitoff. In version -57-, the dev splitoff was simply named
libx264-dev, and this generated much confusion for the dependency engine.
Static library removed beginning with library version -115-.
<<
DescPort: <<
-O1 set for clang issue: http://llvm.org/bugs/show_bug.cgi?id=11859
CompileScript modified so that only encoder/analyse.o is built with -O1
