Flussonic Media Server Documentation


Flussonic Media Server can recognize DVB subtitles, read teletext and closed captions in MPEG-TS and pass them in the format WebVTT for HLS and TTML for DASH.

In this section:

For DASH, the output subtitles formats are WebVTT and TTML, for HLS — WebVTT only.

Flussonic also passes the TTML subtitles in MSS streams - output MSS streams will have subtitles in the TTML format if the input stream has them.
