# TypeType 1.2.2
# TypeType 1.2.3

TypeType 1.2.2 is a hotpatch for YouTube livestreams that could start correctly but then buffer again every few seconds.
TypeType 1.2.3 is a hotpatch for accelerated YouTube playback that could exhaust SABR media windows and repeatedly restart playback.

## Livestreams
## Playback

- keep the server-side SABR pump active while a livestream is playing
- maintain a bounded media buffer instead of waiting for a missing segment before requesting more data
- wake the SABR pump immediately when the player needs another segment
- keep audio and video windows aligned when their timestamps differ slightly
- resolve missing live segment durations from the next available segment
- prevent playback from incorrectly jumping over cached live media
- preserve bounded cache eviction during long playback sessions
- propagate playback speed continuously through the web SABR contract
- size media and server read-ahead buffers for playback speeds up to 4x
- keep rate-aware SABR preparation bounded during long sessions
- preserve the selected video format during recovery instead of switching codec families
- prevent repeated recovery sessions after seeks when playback is faster than the prepared window
- update the MSE runtime to [`@typetype/mse@0.1.43`](https://www.npmjs.com/package/@typetype/mse/v/0.1.43)
