How to validate if close caption is available in a content
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
