TypeType 1.2.3

TypeType 1.2.3 is a hotpatch for accelerated YouTube playback that could exhaust SABR media windows and repeatedly restart playback.

Playback

• 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
