Roku client subtitle support

[velummortis]

Server:10.10.1 on MacOS 10.13 installed via amd64 .dmg from website
Client: Roku 3.0.1

I’m watching a series with Chinese srt subtitles and enabled fallback fonts, directed them to a folder full of necessary woff2 and otf fonts as well as enabled custom subtitles on the client.

Expected behavior: Custom subtitles display on Roku client using provided fonts on the server
Actual behavior: Subtitles display as squares, or sometimes nothing at all - depending on the font.

Works fine if I switch to the ass file I exported though.
I've tried clearing the Fonts folder of all but one otf font, making sure it's <4 MB, renaming it to font.otf, doing the same with a ttf, exporting the internal srts to external srts and repeating all the same steps. The logs give errors processing the internal subs with:

Code:

[ERR] [30] - “MediaBrowser.MediaEncoding.Subtitles.SubtitleEditParser: 57 errors encountered while parsing ‘“srt”’ subtitle using the SubRip format parser” , with errors like: “Line # - Error reading time code”

For every line in the file, but no errors for the external subs, though it still shows nothing.

Does the CJK support only apply to ass/ssa files or is there something else I’m doing wrong?

I do not believe that SRT subs will use server fonts. AFAIK, only ASS subs will use server fallback fonts. And only if the file doesn't attach fonts to the file.

Our documentation appears to confirm this.

https://jellyfin.org/docs/general/admini...back-fonts

The Fallback Fonts installed on the server are loaded up by the web client to render ASS subtitles.

Thanks for letting me know, it was worth a try anyway! Will it be at all possible to override the srt fonts in future releases?

Only if the subtitles are burned in you can provide some modest customization on jellyfin-web based clients. I'm not aware of a way to do the same on Roku clients.
