We are happy to announce that version 3.1.0 is no longer a release candidate. In contrast to version 3.0.x versions, we really tried to make the install process and basic setup more failsafe. We improved the player object code definitions, as well as the example transcoding profiles. We also tried to make the setup to run versus an unpatched ffmpeg as far as possible (only multiple stills and scene detection do not work against the unpatched ffmpeg's).
