About Closed Captions
Closed captions are additional text shown within a video during playback. The captions typically contain an audio transcript of the video.
Benefits of Closed Captions
Closed captions improve the playback experience by providing text-based narration for:- hearing impaired viewers
- viewers who are not fluent in the spoken language of the video
Considerations for Closed Captions
- Although you can technically add closed captions to any type of asset, they make sense primarily with videos, remote assets, and YouTube videos.
- The default behavior of closed captions in Player V3 is "Off". You can enable closed captions with the JavaScript function setClosedCaptionsLanguage(), described here.
- The Ooyala Android and iOS Mobile SDKs use device-defined Closed Captions Style information. However, some devices, including some older Samsung devices, do not support these features.
