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?
  • jellyfin#4053 Fixes issue with audio transcoding to AAC failing to play. Potentially other issues exist with video playback?
  • Issues: jellyfin#3726 jellyfin#3815 jellyfin#3924 jellyfin#3957
  • PR: jellyfin#4053

Blocked

• Fix initial rotation being wrong in app (upgrade expo-screen-orientation)
  • Issue: jellyfin-expo#74
  • Release has not been published to npm yet for some reason. Filed issue upstream.
  • BLOCKED Until Expo 39 is released expo#10055

Complete

• Fix PiP button showing on iPhones
  • PR: jellyfin-web#1873
• 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
• 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.
  • 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, it looks like we can just check for iOS versions < 11.
