Created attachment 523838 [details, diff] avidemux-core-2.7.0-bundled-ffmpeg-lto-fix.patch With LTO the build of media-libs/avidemux-core-2.7.0 fails when linking the libraries of the bundled ffmpeg.

Disabling those direct symbol refs in the bundled ffmpeg's configure fixes the build. The attached patch accomplishes this by creating a patch which is applied by avidemux-core's build system to the bundled ffmpeg sources.
