Where is embe box defined? #19

Open TobbeEdgeware opened 3 years ago

TobbeEdgeware commented 3 years ago

The code defines an empty box "embe" which is 8 bytes similar to "vtte" for wvtt. Where is this box defined?

I cannot find anything in the DASH-IF ingest spec, but Paragraph 5.6 Point 7 mentions filler data and vtte as an example.

It was defined in event message track format MPEG-B part 18, https://mpeg.chiariglione.org/standards/mpeg-4/iso-base-media-file-format/wd-eventmessage-track-format, as filler for timed metadata track with events.
