SOLVED: How to make ass subtitles with external fonts work

[TheDreadPirate]

For the fonts you installed, did you install them in the OS? Or pass them through into Docker? It sounds like this is what you did. My understanding is that system side fonts are only used when burning in subtitles. If the client is directly rendering the subtitles, these would not be used.

Regarding fallback fonts, I believe you have to use the fallback fonts path and provide woff2 formatted fonts. The path is defined right above the check box to enable fallback fonts. Fallback fonts would be used by the client when fonts are not attached to the file.

You could also attach the fonts with ffmpeg since you said they were provided.
