This patchset seems to overlap a bit with AVOptionRanges I think ideally the user should at some point be able to query using some API on a AVCodecContext/AVCodecParameters/AVFormatContex/AVStream what for that specific instance are supported settings for each field The API here seems to use a enum, which can make sense but it differs from how AVOption works which doesnt use enums to identify fields [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Never trust a computer, one day, it may think you are the virus. -- Compn
