Description

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.
