2018-04-24 18:04 GMT+02:00 Antonio <sagitter(a)rpmfusion.org&gt;: Why such change ? ffmpeg is not supported to be multi-arched in a given repository, so you can't have an alternative ffmpeg from another arch anyway. What this is supposed to fix ? Is there a bug tracker ? Also $ rpm -qR moc ffmpeg libFLAC.so.8()(64bit) libasound.so.2()(64bit) libasound.so.2(ALSA_0.9)(64bit) libasound.so.2(ALSA_0.9.0rc4)(64bit) libavcodec.so.57()(64bit) libavcodec.so.57(LIBAVCODEC_57)(64bit) libavformat.so.57()(64bit) libavformat.so.57(LIBAVFORMAT_57)(64bit) libavutil.so.55()(64bit) libavutil.so.55(LIBAVUTIL_55)(64bit) So it seems like moc is already linked to the appropriate libraries. There is no need to use the ffmpeg requires in the first step (or does moc also uses the ffmpeg binaries ?) Thx for your answer. -- - Nicolas (kwizart)
