I just read in the Matroska specs that there’s a flag to force a track to be played.
http://www.matroska.org/technical/specs/index.html
About 1/3 down the page
FlagForced
Set if that track MUST be used during playback. There can be many forced track for a kind (audio, video or subs), the player should select the one which language matches the user preference or the default + forced track. Overlay MAY happen between a forced and non-forced track of the same kind.
That sounds really interesting. I’m especially thinking about the age old problem with DVD-style forced subtitles. Unfortunately Google isn’t too helpful, neither MKVMerge nor AVI-Mux GUI documentation mentions it, and there’s no reference in any player/filter I looked at. So I hope you can help me with two questions.
a) Is it possible to set FlagForced when muxing?
b) Is there a playback solution for Windows and/or Linux that supports FlagForced?
