iOS / iPadOS playback breaks on seek during transcoding due to HLS non keyframe seek request #7451
Description
This issue respects the following points:
- This issue is not already reported on GitHub (I've searched it).
- I agree to follow Jellyfin's Code of Conduct.
- This report addresses only a single issue; If you encounter multiple issues, kindly create separate reports for each one.
Describe the bug
When playing media that requires transcoding on iOS / iPadOS clients (Safari, Jellyfin iOS app, Chrome), seeking forward or backward causes the playback to break.
The server-side transcoding process continues running, but the client playback stops and does not recover.
This log does not appear when seeking in the Android app or in Chrome on PC, and playback works normally.
This issue is partly mentioned here, but it is affecting normal playback.
#7152
Reproduction Steps
- Play a video that requires transcoding on a Jellyfin server
- Make sure transcoding is actually being used, for example by selecting an output resolution lower than the source
- Enable SRT subtitles, either external or embedded
- Use one of the following clients: Jellyfin iOS app, Jellyfin iPadOS app, or Chrome on iOS
- Once playback has started, seek forward several times using the timeline
- Observe that playback may stop, freeze, or show a black screen while the session is still shown as playing in the Jellyfin dashboard
- If the issue does not reproduce easily, increase the transcoding output resolution
- Repeat the seek operation multiple times
- In some cases, the issue is more likely to occur if the server takes longer to generate the first valid video frame after the seek
Expected/Actual behaviour
Resume playback
