#8063 closed defect (fixed)

Unable to choose subtitle language from captions

Reported by: Per Heldal <heldal@…> Owned by: markk
Priority: minor Milestone: unknown
Component: MythTV - Video Playback Version: unknown
Severity: medium Keywords: subtitle caption language
Cc: Ticket locked: no

Description

It is not possible to select language when watching SD-channels that use teletext captions for subtitles. The frontend uses the first available language regardless of language preferences or selection from the menu. The attached image shows the menu with the available subtitle-languages, but only the first alternative (swedish) is displayed. When reopened the menu doesn't indicate the active selection either (it does for DVB-subtitles).

The siparser show the following information for the sample channel:

This ticket doesn't apply to trunk at present. Captions (teletext and subtitles) need some TLC after the recent introduction of a modified player and OSD in order to re-enable this functionality.

Replying to Per Heldal <heldal@…>:

This ticket doesn't apply to trunk at present. Captions (teletext and subtitles) need some TLC after the recent introduction of a modified player and OSD in order to re-enable this functionality.

I've rolled this into a bigger update I'm preparing for the OSD menu. Should be fixed in a day or two.

Resolution: fixed

(In [25640]) Reorganise the OSD Menu.

This creates 8 top level menu items - Audio, Video, Subtitles, Navigate, Schedule, Playback, Source, Jobs - and tries to move the individual menu options into one of those categories.

The OSD menu settings page is removed and the content of the OSD menu is no longer configurable. The next step may be to allow this to be modified through the theme or another xml file.

The names and groupings seem logical enough to me at this point though it is easy enough to tweak them before 0.24. I'm still not entirely sure about Playback, Source and Jobs...

Menu loading should now also be marginally faster as several expensive queries are pushed down one level of the menu.

Also fixes #8063
