Scotty for AntMedia Server

Scotty is a commercial plugin for AntMedia Server that detects SCTE-35 ad break markers in live streams and injects the appropriate HLS signaling tags for downstream ad insertion systems.

When a stream is published to an application that has Scotty enabled, the plugin automatically parses incoming SCTE-35 binary cue points and annotates the HLS playlists in real time — with no segment re-encoding or interruption to the stream.

Features

  • SSAI (Server-Side Ad Insertion signaling): Injects #EXT-X-CUE-OUT, #EXT-X-CUE-OUT-CONT, and #EXT-X-CUE-IN tags so ad-stitching services such as AWS MediaTailor can perform transparent segment replacement.

  • SGAI (Server-Guided Ad Insertion): Injects #EXT-X-DATERANGE with CLASS="com.apple.hls.interstitial" so Apple HLS-capable players fetch and render the configured ad asset at the right moment.

  • Both modes simultaneously — annotate playlists for multiple integration points at once.

  • SCTE-35 detection via binary packet parsing (splice_insert and time_signal commands).

  • Three SSAI tag format options: EXT_X_CUE_OUT_IN, EXT_X_DATERANGE_SCTE35, EXT_X_SCTE35.

  • Per-application configuration — different modes and settings per AntMedia application.

  • Per-stream settings using regex stream-name patterns (streamNameTemplates).

  • Configuration hot-reload without restarting AntMedia Server.

  • Web-based management UI for installing the filter per application and editing settings.
