Title: ffmpeg/libav conflict management: USE=libav Author: MichaŠGórny <mgo...@gentoo.org> Content-Type: text/plain Posted: 2015-01-yy Revision: 1 News-Item-Format: 1.0 Display-If-Installed: media-video/ffmpeg Display-If-Installed: media-video/libav The support for automatic choice between ffmpeg and libav is going to be deprecated in favor of explicit choice via USE flags. This change aims to solve multiple repeating issues, including Portage undesirably wanting to replace one package with the other, subslot upgrade issues and some of the hard-to-understand blocker issues. 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 libav over ffmpeg. Users who currently use libav (the Gentoo default) do not have to perform any action since USE=libav is enabled by default. It should be noted that those users will need to enable USE=ffmpeg on packages with optional libav support as well. Users who want to use ffmpeg instead need to specify USE=-libav explicitly. 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 unless the user changes the global USE=libav state. The most notable example of such package is media-video/mplayer. media-video/mpv may be used as a replacement for users who prefer libav.
