Media agent for Video JS v4.1.2

Highlights

• Added MediaTailor SSAI tracker initialization on loadstart after source load detection.
• Added DAI stream manager support through the stream-manager event.
• Improved bitrate reporting with:
  • Playback bitrate (AVERAGE-BANDWIDTH/BANDWIDTH)
  • Manifest max bitrate
  • Segment download bitrate
  • Network throughput bitrate

Improvements

• Refined ad and content event handling to avoid duplicate or incorrect content events while ads are active for following events:
  • Pause/Resume
  • Seek Start/End
  • Buffer Start
• Improved end-of-content handling for ad-enabled playback paths during IMA and Freewheel scenarios.
• Added safer fallback logic for tech wrappers (Hls.js, Shaka, contrib-hls) when bitrate data is unavailable in VHS.

Technical notes

• Tracker metadata and playback context methods remain aligned with Video.js/Brightcove integrations:
  • Retrieves the title, ID, and duration from mediainfo when available.
  • Retrieves source and rendition data from the active tech component when available.
• Updated the Listener registration and unregistration to include ad and stream manager lifecycle events.
