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 (the Gentoo default) do not have to +perform any action since USE=libav is enabled by default. It should be +noted that the users still 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 in make.conf 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 requiring 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. + +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. diff --git a/2015/2015-02-01-use-libav/2015-02-01-use-libav.en.txt.asc b/2015/2015-02-01-use-libav/2015-02-01-use-libav.en.txt.asc new file mode 100644 index 0000000..aba6d3c --- /dev/null +++ b/2015/2015-02-01-use-libav/2015-02-01-use-libav.en.txt.asc @@ -0,0 +1,19 @@ +-----BEGIN PGP SIGNATURE----- +Version: GnuPG v2 + +iQJ8BAABCgBmBQJUzoW+XxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w +ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2REJCMDdDQzRGMERBRDA2RUEwQUZFNDFC +MDdBMUFFQUVGQjQ0NjRFAAoJELB6GurvtEZOgngP/1/amGltpEmEQka3ak7CK30m +39B2gMaKxa0UEp8Zyiw1Q+QrrtiC0Lu3YVFQBybNBWVASP9DsfuZJbgf0Dnd+oxz +Vcmv7BrDjLQVjeBlqHN2YzjX5yW+GXUm1+nCvq98oGlFZcQRCSkvkmSSV5At5kJE +AkRm2kT0VMaQ3WT2vxdMa5BppmZv7bZoh+s0IgAfE2jvOZNG5yFmoRWhVelI6B0J +eKa5PNPr3aSnyxMQ8YMh6sjLbCeYC3NJkD+P6uWWIKYIpS2QavAZlAjv/7WcmH8U +IKpMA4bcPPnjaS/GJs6PbcG55oF7ltJYwE67IxVj93zEYtpA6yh91cop1iyOvtj4 +529bAQyh439MSCBsY95Zmy/NQv+I73g47KfcGfsUlxR6YJD2jIEppV1lSgqZyv0T +wTXS4ijRTlHKitIPeIsSt5dWKHT1zMi/RR6thR/skRF/JQ5ZJ36MollqU5eud4vP +2oH8AUUVTmhasD5oYWN+6OC6pEpyW19DlgFFonrrXTrEyLHnlt2eL7f4YKHuOV7L +XRvqWlZ6hpM7XO6yaFEp0KseEz8DkYX05qzfZE+f2e0G8cLt9O3hTXf3V+vKI52B +OBQQMA+CQLIBC6ed/qfFmHDByh5G8NsafdmXRwEf1/ZtG3+KKdR+nRcdppn4/VK7 +CKNynotp4jErUq43JD9X +=dgGE +-----END PGP SIGNATURE-----
