+ 29 May 2015; Alexis Ballier <aballier@gentoo.org> ffmpeg-2.2.14.ebuild, + ffmpeg-2.2.15.ebuild, ffmpeg-2.6.3.ebuild, ffmpeg-9999.ebuild: + Do not pass extra-cflags/cxxflags to configure as those default to + CFLAGS/CXXFLAGS respectively. Just disable optflags instead of passing + complete CFLAGS to avoid forced -O3 build: This duplicated CFLAGS on the + compile line and overridden important ones set by configure script; fixes bug + #550554. + please wait a few hours, sync and try again thanks for the report!
