4 Commits • 2 Features
Mar 1, 2025In March 2025, delivered robust media parsing improvements and code-quality enhancements for flowplayer/hls.js, driving reliability, accuracy, and maintainability in streaming workflows. Implemented stronger M3U8 playlist validation, an opt-in ignore of parsing errors for malformed playlists, and improved fMP4 track timestamp alignment to support varied track layouts. Tabled API clarity and type-safety through explicit return types and refined cue indexing, including renaming getFirstCueIndexAfterTime to getFirstCueIndexFromTime. These changes reduce playback interruptions, improve live segment handling, and provide a clearer, more stable API for downstream integrations.
