I am trying to embed some YouTube videos on my website and want to force showing the subtitles. I read about how to do it and now it works but the editor says that there is a mistake "Named entity expected. Got none." It works without mistakes on the website but maybe someone knows how to correct it.
If I place the cc_load_policy=1 right behind the URL as described in most blogs then it does not do what I want which is not showing alternative videos once the video ends or is paused.
thanks for your help!
