1.1.3
September 2026. No API change and no change to the libraries; upgrading is a
version bump.
Changed
- Unselected text subtitle streams (SubRip, ASS/SSA, WebVTT, mov_text) are
now demuxed and decoded too, and the last 120 seconds of each (at most
4,096 events) are kept. Bitmap streams (PGS, DVD, DVB) are still discarded
until chosen.
Fixed
- Choosing an embedded text subtitle track shows the line already on screen
straight away. The engine used to seek back to re-read it: that missed any
line that started before the keyframe it landed on, until the next line,
and flushed the video on the main thread, 57–76 ms per switch on an Apple
TV 4K. It now replays the stream's recent events without a seek. A bitmap
track still seeks. - Styled subtitle events that arrive while libass is still starting are held
and handed to it, instead of being dropped.
