Hi,

I have a dash + playready contents, both VOD and LIVE, that is claimed to contain close caption tracks and is apparently showing on Android and Web but not on Roku. I am using the Video Scene Graph node for playing these contents. Is there a way to validate if close caption is working on Roku? If not, how to troubleshoot it?

Note this is when close caption options is always on but no subtitle tracks

Are they embedded captions? You have to explicitly point the Roku to the captions track when you set the content node, for example:

```auto
  videoContent = createObject("RoSGNode", "ContentNode")
  videoContent.url = my_media_url
  videoContent.streamformat = "hls"
  videoContent.SubtitleConfig = {TrackName:"eia608/1"}
  m.videoplayer.content = videoContent

```
