I was surprised to see that mks-packaged subtitles don't work in Kodi after playing around with them in mpv. Of course these are unrelated projects, but I just thought that mks subtitles were a less obscure feature.
Anyway, would it be possible to adapt code from (lib)mpv to enable Kodi to use mks subtitles?
Failing that, could this be achieved with a vfs add-on, similar to the rar add-on?
