#3310: Missing Font cache messages when using libass? -------------------------------------+------------------------------------- Reporter: DeadSix27 | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: libass,fonts,fontcache,cache,stuck,bug,intended| Reproduced by developer: 0 feature? | Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- I'm wondering, is it a bug or intended, that ffmpeg does not tell you when it's renewing the font-cache (or whatever it does), when I define a new font-folder or add new fonts. ffmpeg stucks (seemlinly, due to not saying anything) "scans the fonts" as I assume.. and continues with my encode.
