I have multilanguage subtitles in .sub/idx format. Infuse can see them, but wont display anythink. If I open the video and subtitles with IINA in my macbook pro, then I can select the language and get everythink working. Is there coming support for these subtitles also?
SUB/IDX pairs are not currently supported, but may be something we look at for a future update.
Moving to suggestions for now.
You can easily convert your .sub files in srt using Subtitle Edit (free open source program ).
srt subtitles, besides being supported universally, are far more flexible. IMHO well worth the effort to convert them (or you can download the srt sub directly)
