How to Use
Multilingual subtitling is supported for HLS adaptive bitrate streaming. To use this feature, you need to add a subtitle set to the media file by calling the ModifyMediaInfo API. You can use the input parameter
AddSubtitles.N to add subtitles and the input parameter DeleteSubtitleIds.N parameter to delete subtitles. The API will return a list of the added subtitles (the output parameterAddedSubtitleSet, which contains the ID of each subtitle).After a subtitle set is added to a media file, you can associate/unassociate the subtitles with an existing adaptive bitrate streaming file by calling the AttachMediaSubtitles API. You can also initiate a new adaptive bitrate streaming task and set the task’s input parameter SubtitleSet (MediaProcessTask > AdaptiveDynamicStreamingTaskSet >
SubtitleSet).Was this page helpful?
