Newish versions of ffmpeg have introduced a new shared library which due to the same reasons as the already special-cased libavcodec-*.so and libavformat-*.so needs to be set textrel_shlib_t. Fix attached.
Created attachment 122537 [details] Set libavutil-*.so as textrel_shlib_t
Fixed in selinux-policy-2.1.6-15.src.rpm
