Composer 3.2.4

March 19, 2025

DASH SSAI Update

  • Handle out of sync trick play adaptation sets when creating new periods for ad breaks. Sometimes a source packager trick play lags behind the video and audio streams causing timing calculations to change and be incorrect over time. This change ensures such divergence will not result in inconsistent manifest rendering.
