It seems that the player.getVideoData() disappear from the player object. In the official Youtube documentation the method can't be find : Official Youtube Developers Documentation
But this usefull method was used to get datas about video like the title as we can see in this ticket for example : Get YouTube video info from iFrame embed API
It seems it disappears the 2017/11/14 but I don't see release note about this : Official Youtube Developers Documentation
Do you have some informations?
Do you know if we have a new way to get the title of the video (from youtube not in our own html)?
Thanks
Regards
