Caption Support
Fire App Builder supports the same closed captions/subtitles that Exoplayer supports. The formats include TTML, WebVTT, and CEA-608. The priority of support is as follows:
- CEA-608 inband (if enabled — see below)
- WebVTT and TTML outband
- WebVTT and TTML inband
To enable inband CEA-608 closed captions, open Navigator.json (located in app > assets). In the config
object, add "enableCEA608": true
. Here's an example:
{
"config": {
"showRelatedContent": true,
"useCategoryAsDefaultRelatedContent": true,
"searchAlgo": "basic",
"enableCEA608": true,
"enableRecentRow": true,
"enableWatchlistRow": true,
"maxNumberOfRecentItems": 5
}
