[Android]: SetGlobalOption("subtitles.fonts.dir", ...) does not work

[sbenmeddour]

Describe the bug Set global option with "subtitle.fonts.file" is working fine, but "subtitles.fonts.dir" isn't working Mdk seems to correctly find the files, but not libass

To Reproduce mdk::SetGlobalOption("subtitles.fonts.dir", value);

I tried with java File path, asset path, no difference

Expected behavior Libass should try to use the provided dir, but it seems it searchs in /system/fonts dir

Environment:

• OS: Android
• GPU: optional

The libass.so in the sdk is a patched version, it does not support fontconfig. You can extract libass.so from kodi and try that one
