A Jellyfin user has shared a frustrating experience on r/jellyfin: after about half a year of smooth operation, some files suddenly take a very long time to start playing. The setup is a Jellyfin server on TrueNAS with an NVIDIA Shield Pro as the playback client. The user is careful to point out that playback itself is fine once it starts — this is not intermittent buffering, but a long wait before the stream begins.
After feeding logs to an LLM in an attempt to find the cause, the user was pointed toward subtitle extraction, which in some cases took 30 to 60 seconds. As a workaround, they set up Bazarr to extract subtitles into separate files. That helps, but not completely: when they need to pick a different subtitle track — because the extracted one is in the wrong language or out of sync — the long loading returns. The user notes they used Emby and XBMC before Jellyfin and had not run into this before, and is asking the community which settings to adjust.
Who this affects
Anyone running Jellyfin on a NAS or similar self-hosted box with embedded subtitle tracks in their media files. The reported pattern is a delay at the start of playback rather than during it, which makes it easy to misdiagnose as a network or client problem. The user's setup — server on TrueNAS, Shield Pro as client — is a common one among self-hosters, so the report is likely to resonate.
Why it matters
Subtitle handling sits on the critical path between pressing play and seeing a picture. When extraction is slow, the whole experience feels broken even though the server and network may be perfectly healthy. The user's partial workaround with Bazarr also shows the limits of pre-extraction: it removes the delay for the track you prepared, but not for the alternatives you occasionally need.
A note for self-hosters
The thread is a question, not a confirmed diagnosis, and the source does not name a specific setting or fix. If you see similar symptoms, the practical takeaway is to look at subtitle-related log entries when playback stalls, and to consider whether pre-extracting subtitles is worth the trade-off for your library.
