when Subtitle configured with "WebVTT" output segments, the mpd has

<AdaptationSet codecs="wvtt" contentType="text" id="3" lang="eng" mimeType="application/mp4"

HbbTv expects only "stpp" (TTML output) as codec for subtitle. So it reported error for webVTT. Is this expected?

This check is implemented not for HbbTV but for DVB DASH specification. As far as I can see in the code the error is printed for DVB profiles.

Could it be that:

the tested MPD contains a DVB profile in the @profiles attribute or
when testing "DVB" was selected from the "Enforce profile(s)" (when clicked on the Settings icon on the webpage)?

If either of them is correct, then the printed error is valid.

Closing as there was no further feedback.
