Since we're using an old version of x264 (http://ftp.videolan.org/pub/x264/snapshots/x264-snapshot-20120827-2245-stable.tar.bz2), this bug (http://git.videolan.org/gitweb.cgi/x264.git/?a=commit;h=f6a8615ab0c922ac2cb5c82c9824f6f4742b1725) has not yet been fixed causing x264enc to crash when run on an iPad4 (iPad2 is unaffected). Applying this patch on /common/cpu.c solves the problem: http://git.videolan.org/gitweb.cgi/x264.git/?p=x264.git;a=patch;h=f6a8615ab0c922ac2cb5c82c9824f6f4742b1725
This should be fixed now: commit 6de19224eb7c6cdc26da66d399f10cac2bbdb249 Author: Jan Schmidt <thaytan@noraisin.net> Date: Thu Feb 13 14:26:14 2014 +1100 x264: Update to 20140212-2245-stable Fixes a crash when compiled with gcc 4.8
