In-stream SEI metadata

The Dolby OptiView Live platform allows you to embed metadata into your stream using SEI (Supplemental Enhancement Information) messages. This metadata is preserved throughout the pipeline and can be accessed by the player during playback.

Configuring in-stream SEI metadata​

  1. Add metadata to your H.264 input stream in the form of picture timing SEI messages, as defined in ITU-T H.264 Annex D 1.3. These messages allow you to attach a timestamp to individual frames and associate it with an event on your backend.
  2. Start your channel and begin ingesting video with embedded SEI data.
  3. Listen to these messages in the player to consume the metadata during playback.
