Is there any particular reason that PGS subtitle tracks (blu ray .sup tracks) aren’t supported as sidecar files, while .sub/idx tracks are? i know either need transcoding in most cases, but pgs tracks don’t show up unless muxed in the individual video files. ultimately, i’d like to have the pgs tracks available as a backup to srt or ass tracks, especially where text placement is key (on-screen translations in anime, for example)
