This change aims +to solve multiple repeating issues, including Portage undesirably +wanting to replace one package with the other, lack of proper reverse +dependency on ffmpeg/libav upgrades and some of the hard-to-understand +upgrade failures involving blockers. It also may be used to make ffmpeg +and libav co-installable in the future. + +The current USE=ffmpeg will maintain its role of enabling optional +support for ffmpeg or a compatible implementation (libav) in a package. +However, whenever appropriate additional USE=libav will be introduced to +control the preference of one implementation over the other. + +Users who currently use libav need to enable USE=libav in +/etc/portage/make.conf. It should be noted that users still need to +enable USE=ffmpeg on packages with optional libav support as well. +Users who currently use ffmpeg need to take no action. + +Please also note that some packages support only one of the two +implementations. An attempt to install one of those packages may result +in blockers requiring the user changes the global USE=libav state. + +Please do not alter the state of 'libav' flag on a per-package basis +(e.g. via package.use). The flag needs to be set globally to have +consistent value throughout all packages. Otherwise, blockers will +prevent upgrades. |
