Hi 

I've implemented the closed caption support using WEBVTT format as the source for the subtitles.
The subtitles display fine, including the positioning, however neither the colour or any html entities (<) within the text are displayed.

A snippet of the vtt file is as follows:

WEBVTT

NOTE: MatID = 56966001001001   Title = ************               
NOTE Created by .sng webVTT Encoder module WriteVTT v2016_10_28-1


1
00:00:02.000 --> 00:00:07.000 line:77%  position:50% align:middle
<c.white>This programme contains strong</c>
<c.white>language and adult humour.</c>

Can anyone explain if this format is supported by Roku?

Regards

As of 8.1, the only HTML tags that are handled by the WebVTT parser are <b>, <i>, and <u>. The HTML entities for amp, lt, and gt are all parsed and should result in the correct character showing up in the subtitle output, but there may be a bug here.

Thanks for this. I am certainly not seeing the &lt; entity.

So for example the following embedded tag in the vtt file will not be recognised by the Roku parser : <c.yellow> ? Is there no way of including the style yellow?

At the moment, there's no way to specify color information in a WebVTT file.
