forced subtitle display on playback with matroska + vobsub

[beandog@…]

With r28035, when playing a MKV file encoded from a VOB (MPEG2 + AC3) + VOBSUB tracks, mplayer will automatically display the subtitles.

No amount of config options (-noautosub, etc.) will disable displaying them by default. The only way to turn them off is to toggle them off (hit 'j').

Whoops, that was r28227.

-sid 999 should do it
in config or whatever :)

then using -sid or -slang or j / v key will turn subs on again.

Yes it works for playback thanks, but realy it is only a workaround.
It have to be fixed.

Reimar,

One reason that has been brought up before is that since the subtitle track is flagged as "default" then it should be showing up. Setting a track without the default flag still displays it by default as well, I've noticed.

$ mkvmerge -o movie.mkv movie.vob --default-track 0:no --forced-track 0:no movie.idx

$ mkvinfo test.mkv

Gosh dang it ... another case of user error. It was loading the autosubs from the same directory.

So, to clarify, it *does* work correctly if you use mkvmerge with --default-track 0:no before the .idx file.

Whether that's odd that mkvmerge automatically flags subtitles as default or that mplayer automatically displays them is a matter of opinion at this point, I suppose.

this is fixed with -nosub option now.
