# Jellyfin on iOS Hack Week

## To Do
- [ ] Investigate iOS remote (and in some cases local?) playback being broken since server version 10.5.0
- Maybe this is just a generic error when the max bitrate is exceeded? iOS would be affected more since it lacks support for detecting the bandwidth and uses a low hardcoded value instead...
- Manually setting bitrate limit seems like it may prevent the issue.
- ~~Possibly related to the changes in [jellyfin#2160](https://github.com/jellyfin/jellyfin/pull/2160)?~~
- [jellyfin#4053](https://github.com/jellyfin/jellyfin/pull/4053) Fixes issue with audio transcoding to AAC failing to play. Potentially other issues exist with video playback?

## Complete
- [x] Fix PiP button showing on iPhones
- **PR:** [jellyfin-web#1873](https://github.com/jellyfin/jellyfin-web/pull/1873)
- [x] Fix recent iOS versions on iPads not being properly detected
- This could cause various issues like the desktop interface being displayed and audio failing in Live TV playback
- **PR:** [jellyfin-web#1880](https://github.com/jellyfin/jellyfin-web/pull/1880)
- [x] Investigate video playback failing on old iOS versions (10 and possibly others?) since server version 10.5.0
- Old iPhone and iPad devices do not support AC-3 and E-AC-3. See this [support matrix](https://developer.dolby.com/platforms/apple/ios/device-support/).
- Need to somehow improve support for detecting which devices actually support these audio codecs.
- Testing with `canPlayType` reports "probably"/"maybe" for support of these codecs. Which is not a good indicator of if the device actually supports playback since devices that do support it only report as "probably".
- Based on this [max iOS support matrix](https://iosref.com/ios), it looks like we can just check for iOS versions < 11.
