I believe distribution packagers of VDR (at least myself) will want to install the VDR locale files into the standard directory under /usr/share/locale/, where all other locale files are.
However, as that directory may contain lots of other locales that do not have translation for VDR (or possibly only for some plugin of VDR, which applies to a custom localedir as well), those show up in the OSD Language selection menu as "LanguageName$English".
Also, it could also be possible that the I18N_MAX_LANGUAGES = 256 constant could be too small for some systems. I guess it could be modified to limit only the locales that have VDR translation, not the total locale count in the system.
+void I18nRegister(const char *Plugin) +{
- bindtextdomain(Plugin, I18nLocaleDir);
+}
[...]
if (Plugin)t = dgettext(Plugin, s);
Maybe it would be better to use something like vdr-PLUGIN or vdr-plugin-PLUGIN?
If the translations are installed into /usr/share/locale, the files of VDR plugins could conflict with other programs that have the same name, if the plugin translation files are not prefixed by anything.
