Description Bastien Nocera 2011-04-07 13:50:22 UTC 
It's currently impossible to select the favourite menu/audio track/subtitle languages for DVDs played, as resindvd will use the current system language as the favourite language in all occasions.
Comment 1 Tim-Philipp Müller 2016-04-11 13:46:57 UTC 
Right, currently it will use g_get_languages() and go through those in order to match them against what's available on the DVD.

I think the main issue here is DVD menu selection?
Audio/subtitle tracks can/should probably be done higher level (playbin)?

Do we really need this configurable? Perhaps there should be GLib API to override this then? Or a global (app) setting in GStreamer?
Comment 2 Bastien Nocera 2016-04-14 14:03:25 UTC 
I don't know exactly how it works when no language is explicitely selected in the menus. I would expect that, if there is a configuration on the user's side, to not use the user's languages, but whatever the user configured.

It might get complicated when the user choices could be:
- if the default audio track is in Chinese, select the Chinese audio track and subtitles in one of those languages I can read
- if the default audio track is in English, show the English subtitles
- if the default audio track is in French, don't show me anything

I don't know how the configuration UI would work for that, but the easiest might be for a collect signal, pass in the audio and subtitle tracks available as soon as they are there, and let the front-end return which ones it wants to be played.

But I don't know whether that would make it any different from waiting for the "tags" and switching the audio/subtitle track in the app...
