1.3.1

November 2026. No API change and no change to the libraries; upgrading is a
version bump.

Fixed

• An HLS stream whose master playlist lists subtitle renditions no longer
  waits on them to start. libavformat fetched each rendition's segments inside
  the audio and video read, so a server slow to produce subtitles held back
  the picture and the sound: on a Jellyfin remux with 35 renditions, 4 s at
  start with the subtitles cached and 32 s while the server extracted them.
  The renditions are still listed, so track ordinals do not move, but they are
  never read, and choosing one does not seek. Deliver HLS subtitles as
  external files instead.
