This is a feature request.
If a guest visitor has no permission to view a video, the player will not play the video, instead, it will show a warning message as an overlay on the player window:
Sorry, you've no permission to watch this video
Don't you think such a brutal cold statement will make the visitor confused and uncomfortable? He must want to know: why I can not view this video? How can I get enough permission to view it?
However, this warning message can NOT answer above questions.
My suggestion is: make this warning message more friendly by allowing it show
HTML LINK as detailed explanation.
That is to say, we allow HTML format of warning message to replace the current plain text message.
Then, there will be a link inside the message, and the visitor can click on that link, and be brought to an page (maybe an article) where he can find detailed explanation and instruction on how to get proper permission to view that video.
