 Hello,

 After ffmpeg version around 20131026 (2.0.2) the Matroska files created
 are not fully compatible with some players (especially hardware BluRay
 players). This problem is well known in other mkv muxers (as mkvtoolnix),
 and they have implemented options to disable some new features in the
 matroska muxer. See the features that can be disables in
 https://trac.bunkus.org/wiki/FAQ%3AImprovingPlaybackCompatibilityWithPlayers

 The MKV file generated using these features is a version 4 MKV, but many
 players only support version 2. Is it possible to implement options in the
 ffmpeg matroska muxer to disable these new features of matroska
 specification?

 Thank you and best regards.
