Updated version: Title: FFmpeg default Author: Ben de Groot <yng...@gentoo.org> Content-Type: text/plain Posted: 2015-04-07 Revision: 1 News-Item-Format: 1.0 Display-If-Installed: media-video/ffmpeg Display-If-Installed: media-video/libav Since the choice between ffmpeg and libav has been made more explicit, there has been a lot of discussion about what the default implementation should be. It can be concluded that media-video/ffmpeg has wider support, and would be somewhat more convenient for most end-users. For this reason the default implementation has been switched back from media-video/libav to media-video/ffmpeg by removing the libav useflag from the base profile. If the libav useflag is already globally enabled or disabled in /etc/portage/make.conf, then no further action is required. Users who implicitly relied on libav being enabled in their profile, and who wish to continue using libav, should enable USE=libav in their /etc/portage/make.conf file. > Also please prepare an update to the USE=libav news item to state > updated default.
