It’s likely that CaptionHub Live is compatible with the output of your streaming provider. Please contact us if you want to discuss compatibility of your streaming setup.
HLS stream requirements
- The stream needs to be publicly accessible
- The stream can’t use encryption or DRM
- The stream needs to use MPEG-TS. We don’t currently support Fragmented MP4 (fMP4). This also means that LL-HLS is not supported.
- Segments need to have a
#EXT-X-PROGRAM-DATE-TIMEtag in order to be used with a player plugin.
- If using a separate audio feed, segments need to use MPEG-TS in order to be used with HLS integration. Using Packed Audio is not supported.
- The minimum segment size is 5 seconds, and minimum total playlist size is 15 seconds.
- The HLS stream needs to allow CORS in order to provide a preview inside CaptionHub.
Supported HLS features
- When using separate audio playlists, the default audio stream will be transcribed.
