wse-raskenlund-captioning¶
wse-raskenlund-captioning is a commercial plugin for Wowza Streaming Engine that allows adding
CEA608 and WebVTT closed captions as well as rendered open captions to live streams in Wowza Streaming
Engine via REST API calls.
The functionality has been divided into a set of smaller modules which need to be added and configured as required by the use-case.
You can find a complete list of configuration options for each module under the relevant section in the Configuration chapter.
ModuleOnTextDataToCEA608¶
This module transforms onTextData events in the incoming RTMP stream into CEA608 captions.
Combined with the HttpProviderCaptionApi provider, you can use this to place CEA608 captions
into your stream sourced from REST API calls.
ModuleLiveOpenCaptions¶
This module transforms onTextData events in the incoming RTMP stream into open captions (aka. burnt-in)
captions. When used together with the HttpProviderCaptionApi provider and Wowza Transcoder, you can draw
captions onto the outgoing transcoded video stream sourced from REST API calls.
