ModuleOnTextDataToCEA608 and rollup style

We have been using ModuleOnTextDataToCEA608 to output our own captions.

We add the captions as AMF data using

stream.sendDirect(“onTextData”, amfData);

The captions are present in the output HLS stream (although seem to clear prematurely in the web player we use (theoplayer)).

We would like to try using the ROLL-UP style to see if that gets round this issue.

Is there anyway we can get our subtitles outputted with that style?

We have tried to set VTT as the output format (in Closed Caption properties) however we seem to have empty VTT files in the output stream.

Hope someone can help, thanks
