I’ve never used Findroid, but they work on my regular Jellyfin app. I think on Roku transcoding is required, but afaik that’s on Roku not supporting the subtitle format.

I now extract all my subs, but for the first 2 years using it I left everything embedded and it always worked normally. Even with some advanced ones like Jujutsu Kaisen and One Pace, which both use stylized ones.

Yes. You set hardware encoding to QSV, then you’re mostly set. You can choose which formats it should work on, which for an Arc card will probably be all of them. I got an Arc A380 and its worked flawlessly with many streams at once.

Fair enough, not saying you should bother with it, just surprised to hear it happening.

I genuinely do not understand the issues people are having with Jellyfin subtitles. I just have Bazarr set up to automatically download and they play on every device (web, android, iOS, roku, android TV) with zero issues.

Embedded subtitles definitely work, and I’ve used bitmap ones before, although I generally avoid them so I’m not sure if they consistently work well. Directly playback also does work with those subtitles, so if you had issues it was likely related to codec support.
