Subtitles

Allows display of WebVTT subtitles in the player

Installation

Include the plugin next to the core player:

<script src="//cdn.flowplayer.com/releases/native/stable/flowplayer.min.js"></script>
<script src="//cdn.flowplayer.com/releases/native/stable/plugins/subtitles.min.js"></script>

<!-- load playlist plugin if you need subtitles in playlists
<script src="//cdn.flowplayer.com/releases/native/stable/plugins/playlist.min.js"></script>
-->

Create a custom player with subtitles on the configuration builder

Supported formats

The plugin supports webVTT text track files as well as embedded WebVTT in an HLS m3u8 manifest, plus CEA-608/708 and SCTE embedded captions. For all embedded types you do not need to configure the tracks object; all configuration comes from the stream. This also means you cannot override the label or default.

Configuration

Subtitles are configured in the clip (for playlists) or player level object subtitles and the child object tracks, which can contain multiple subtitle tracks in different languages.
