Providing subtitles as part of live streaming is important and is required by law is some countries. So people ask adding that capability into Nimble Streamer in addition to VOD subtitles support.
There are cases when source stream which comes into Nimble Streamer already contains subtitles metainformation. So now Nimble allows forwarding CEA-708 subtitles. This means that all outgoing streams for all supported protocols will include subtitles.
This works for both transmuxing and transcoding of H.264 (AVC) content.
Transmuxing support this forwarding by default. Whatever metainformation is inserted into the original stream, it is passed through to all other protocols.
To make this work in Live Transcoder scenarios, you need to enable this feature for outgoing streams. It's a premium add-on for this media server and it has easy-to-use web UI to control transcoding behavior. To install and get a license for it, visit this page.
To enable this feature for particular encoded stream, you need to edit an encoder block for the stream which you want subtitles to be forwarded for.
Click on encoder details icon to open encoder details dialog.
Check the Forward CEA-708 subtitles box and save settings to close the dialog. Then click Save on scenario age to apply it on server.
That's it - the forwarding will start working right after a scenario is saved on server.
Also take a look at DVB subtitles processing and SCTE-35 processing which can also be passed through Live Transcoder.
